World Water Day – March 22, 2019
Water is the building block of life. For some, it’s easy to take water for granted..."it just comes out of the faucet anytime you want it." Yet around the globe, there are people who don’t have access to clean, safe drinking water. March 22, World Water Day, is dedicated to drawing attention to the water related issues that affect humans in almost every country. As created by the United Nations, the goal of World Water Day is to bring aide to people who are truly in need.
Try to reduce your water footprint:
Earth is the only known planet in our solar system that humans can live on. No other planet has oceans, Earth is also our only known planet to have bodies of liquid water on its surface and enough oxygen to comfortably breathe. Because we have so much water, Earth is is also referred to as the Blue Planet. The oceans combined with the atmosphere makes our planet look blue from outer space.
About 71 per cent of the Earth's surface is covered with water. Earth is the only planet where water can exist in liquid form on the surface. Less than one percent of Earth's water is drinkable. Most of Earth's water is salty (~ 97%) and over 2/3 of Earth's freshwater is frozen. Earth is the fifth largest planet and the third planet from the Sun.
What is potable water? Water that is suitable or safe for drinking.
Water is not distributed evenly across the Earth. Water can be found in oceans, lakes, rivers, glaciers, underground (ground water), in soil and in Earth's atmosphere. A molecule of water can remain in the ocean for thousands of years. A molecule of water can remain in the atmosphere for as short a time as just a few days.

An estimated 780 million people live without clean, accessible drinking water. Drinking contaminated water can lead to a host of life threatening diseases. Although this may seem like a third world problem, Flint, Michigan showed us that water problems even plague the United States.
Our wildlife also require access to clean water. Every year, countless animals die as a result of water pollution. Pollution can occur in many ways, from physical litter to wastewater and chemical runoff, which causes the water to become toxic to the animals that depend on it for drinking and habitation.
Many of the environmental problems we are coping with are intertwined — such as climate change and ecosystem degradation are related to and sometimes direct causes of water pollution, floods and droughts. — https://nationaltoday.com/world-water-day/

#MountainsMatter: International Mountain Day 2018 Theme
Mountains matter yet they are often forgotten. Mountains play a vital role in providing essential "goods and services", especially water, to our planet. Mountain ecosystems are centers of biological diversity. These ecosystems, however, face severe threats from unsustainable land use practices (ex. overgrazing or non-conservation agriculture), illegal wood extraction, development of large-scale infrastructure (dams, roads) and unsustainable natural resource projects (fossil fuels, mining, & increased hydrocarbons). Our human well-being and livelihoods cannot be sustained without healthy ecosystems. Mountains also provide vulnerability in the "face of climate change", People living among mountains face subsistence challenges brought about by elevation, rough topography and even severe climate. https://adaptation-undp.org/projects/mountain-eba

#MountainsMatter for Water: Think of mountains as the world’s 'water towers’, providing between 60-80% of all freshwater resources for our planet. Reliable resources indicate that glaciers in mountain ranges around the world are retreating and disappearing due to climate change. As many as 600 glaciers have disappeared completely over past decades, affecting water supplies relied on by billions living downstream.

In 2018, we celebrated the 50th Anniversary of the Wild & Scenic Rivers Act. We continue this celebration in 2019 as tribute to the 50th Anniversary of the Little Miami River being named a State and National Scenic River.
#MountainsMatters for Disaster Risk Reduction as climatic variations are triggering disasters. Avalanches, mudflows and landslides are tumbling downstream, stripping bare forests, flooding communities and populations.
#MountainsMatter for Tourism: Mountain destinations attract roughly 15-20% of global tourism; these are areas of important heritage, knowledge and cultural diversity, . Such tourism has potential to affect or foster economic development especially in remote and isolated regions. Unfortunately, many mountain communities are not benefiting and still live in poverty.
#MountainsMatter for Food: Mountain regions are important centers of agricultural biodiversity; they are "home to many of the foods that come to our table"...rice, potatoes, quinoa, tomatoes and barley. Sadly, such regions are home to some of the hungriest peoples in the world given a high vulnerability to food shortages and malnutrition; climate change is directly affecting mountain agriculture.
#MountainsMatter for Youth: Despite magnificent landscapes, rural life in mountainous regions can be "tough", particularly for the youth; abandoning their villages in search of employment elsewhere has lead to an absence of young people. This directly increases labor shortages. Consequently, migration from mountain regions has lead to an increase in abandoned agricultural, land degradation to even forest fires. Consequently, many cultural values and ancient traditions are lost.
#MountainsMatter for Indigenous Peoples: Many mountainous areas host ancient indigenous communities that often posses and maintain unique knowledge, languages and traditions. Mountain peoples have developed unique land-use systems; they posses a wealth of knowledge and strategies that have accumulated over generations, including how to adapt to climate variability.
#MountainsMatter for Biodiversity: Half of the world’s biodiversity hotspots are concentrated in mountains where approximately 25% of terrestrial biological diversity is supported. Mountains are home to many rare wildlife such as gorillas, snow leopards, the majestic tahr and strikingly, beautiful plants such as orchids and lobelias. International Mountain Day is an occasion to create a large social movement that can bring mountain issues "at large".
Take a "step-up" and raise attention to mountains. #MountainsMatter

Winter at Yellowstone National Park indicates fewer crowds, frigid temperatures, and steaming geyser basins, hibernation or even migration. Skis, snowshoes and snowmobiles are often the primary modes of transportation as roads close, rivers and lakes freeze and snowstorms transform the park. One of the most amazing winter sights at the park is the ice dam at Lower Falls. Often growing over 100 feet tall, it’s known as an "astounding natural spectacle".

Geologists create a basic unit called a formation to classify and map layers of rock. Thus, a formation is a rock unit that is distinctive enough in appearance that a geologic mapper can tell it apart from the surrounding rock layers; also, the rock formation must be thick enough and extensive enough to plot on a map.
"Formations are given names that include the geographic name of a permanent feature near the location where the rocks are well exposed. If the formation consists of a single or dominant rock type, such as shale or sandstone, then the rock type is included in the name." - By Christine Wilkerson, Utah Geological Survey "What is A Formation?"

Encompassing a 1,500-mile system of winter trails, the Iditarod National Historic Trail initially connected ancient Alaska Native villages and opened up Alaska for the gold rush; it continues to play a vital role for travel and recreation. This trail is maintained by the Bureau of Land Management and it is often identified with the famous annual Iditarod - sled dog race. This annual race starts each year in March. There are upmost challenges the racer and the 21-dog team face given harsh conditions across rugged but beautiful Alaskan terrain. Meanwhile, dog mushing is the traditional Alaska winter transportation. Dogsledding, or the practice of a musher guiding a team of dogs pulling a sled over ice and snow, may serve multiple purposes. "Whether it’s a casual run along public recreational trails, racing against competitors, or hauling supplies, public lands have much to offer." -https://www.blm.gov/programs/recreation/recreation-activities/alaska

"Student project leads to 1st foam tray recycler in state"
"What began as a Little Miami middle school research project has led to a first-of-its-kind Styrofoam tray recycler in Ohio." Instead of sitting in a landfill for centuries, used Styrofoam school lunch trays are being converted to paving bricks. After undergoing a process called densification (short 10 hour process), the trays are converted into a single square brick that feels like glass or tile but is solid as a rock. Densification involves removing air from Styrofoam and using heat to melt it into a liquid resin that, when cooled, forms bricks from bundling multiple foam lunch trays.
Foam lunch trays turned into reusable products:
Little Miami is the first school district in the state of Ohio to use a StyroGenie machine to create a closed-loop recycling system for the foam trays used in some of the district’s cafeterias. Findings included that this machine presented a possible cost effective path to reduce the schools’ foam tray footprint by more than 90%, reducing trash volume and waste disposal costs.
Save money by decreasing waste removal costs:
"The StyroGenie is a low cost machine that is easy to use and is a responsible choice for the environment. Standing at six feet by four feet, the StyroGenie can hold up to 1200 trays in each cycle. While it takes about ten hours for the trays to be densified, the machine only uses the same amount of electricity as an average hair dryer. In addition, it operates without any moving parts or harmful emissions, making it safe for the environment." -
Little Miami Schools Food Service Director, Rachel Tilford, purchased the StyroGenie machine for the Little Miami District after learning about its existence through a group of middle school students (members of a local First LEGO League team). The team’s challenge in the 2015 competition was to identify a piece of trash to research and invent a solution to "help the trash problem". The students chose Styrofoam cafeteria trays; they researched ways on how to reduce waste in Little Miami lunchrooms. That’s when they found out about the StyroGenie.
View in the News video:
Thank you Mrs. Tilford for taking extra time to meet with Warren County Soil and Water Conservation District and with our LMHS Intern and Volunteer, Ms. Honigford.
We also extend our gratitude to LMJH Principal, Mr. Ryan Cherry, for sharing more about the recycling efforts on a "school wide" basis. We enjoyed learning more about this phenomenal idea and how the idea came about.. We hope more districts can "get on board".
Other StryoGenies in the news - Lake Hills Elementary School, Michigan City,
"The school's trash output in the cafeteria has gone down from 52 to 15 bags a day."
The cost of the StyroGenie for Lake Hills Elementary was $12,000, "but it should pay for itself in two years from refuse disposal savings." Plus, "It's the right thing to do," - STEM coordinator at the school said,
Bricks were painted and placed in the school garden for decorative purposes and for a walkway incentive. The city's street department was contacted for additional use for the bricks.
"In addition to promoting a safe environment, the Styro-Genie shows students what is possible if they open up their minds." Lake Hills Elementary is also preparing kids to be problem solvers and creative thinkers as to solve some of the problems the world might have in the future.

OHIO'S SCENIC RIVERS
Celebrates 50 Years of Conserving
Rivers, lakes and oceans - our blue spaces benefit both our physical and mental well-being. We rely on rivers for clean drinking water and as places of recreation and rejuvenation. Even the sound of moving water has a calming and restoring effect on the mind. Whether you are looking for a peaceful picnic or rest spot by a babbling brook, a scenic river-front hike or a place to paddle, you can find activities along Wild and Scenic Rivers that contribute to your good health.
Wild Scenic Rivers Health & Safety: www.rivers.gov/wsr50/files/health-safety-infographic.pdf
Roughly 65% of our nation’s drinking water comes from rivers and streams. Toxins that contaminate water can harm the human body, meaning that "good health starts with good water chemistry".
Many plants and some animals, such as freshwater mussels, can filter water by removing harmful chemical compounds. Since humans need assistance making sure the water we ingest is clean, protect your own health by understanding the ecosystems responsible for your clean water and helping your local watershed group clean up litter -
thus removing water pollutants.

Rocks and minerals are all around us and used in our everyday lives. They also help us to develop new technologies. Rocks and minerals are used in building material, cars, roads, appliances and even in cosmetics. Humans need to consume minerals on a daily basis in order to maintain a healthy lifestyle that includes strengthening the body. Abiotic features, like rocks and minerals, play a valuable role in our natural systems such as providing soil nutrients in Redwood where the tallest trees in the world grow or provide habitat like the cliffs at Grand Canyon National Park where endangered condors nest. We can learn more about Earth's materials, structure, and systems through studying rocks and minerals.

World Environment Day is a global celebration of nature, a day to reconnect with the places that matter most to you. It is a "People's Day" of action to do something to take care of the earth and be an agent of change. The 2017 theme is connecting people to nature. Our personal connections to the environment fuel our desire to protect and conserve nature for current and future enjoyment. So today, think of your favorite spot outside and go there! Take a moment to breathe in deep and reflect on why this spot of nature resonates with you.
One of my favorite spots to be outdoors in Warren County is Miller Ecological Park. Whether going for a hike or playing with my daughter on the Nature Playscape, I can submerge myself in nature even while still being in the city of Lebanon.
Warren County Park District manages many beautiful areas where you can connect and enjoy the outdoors!
For a list of other wonderful parks throughout Warren County where you can get out into nature, visit https://trekohio.com/warren/
So on this World Environment Day, we encourage everyone to reconnect with the natural world around them, and remember why it is so important for all of us to be responsible stewards of our natural resources!
What is a Fossil?
A fossil is the naturally preserved remains or traces of organisms that lived in the geologic past. There are two main types of fossils; body and trace. Body fossils include the remains of organisms that were once living and trace fossils are the signs that organisms were present (i.e. footprints, tracks, trails, and burrows).
"Any direct evidence of ancient life, including the remains or traces of plants or animals. The term "fossil" does not include any life forms that have been buried since the beginning of historic time." - www.ohiohistorycentral.org/w/Fossil
Ohio's Geologic Timeline:
"Since the oldest sedimentary rocks
in Ohio were deposited first,
they lie below the youngest rocks.
Therefore, if a layer of sedimentary rock
lies on top of another layer of such rock,
the top layer is younger than that beneath it.
This holds true in Ohio EXCEPT in cases
where a force has disturbed the layers
after they were deposited." - www.ohiohistorycentral.org/w/Ohio%27s_Geologic_Timeline
Fossils of Ohio –
A great tool to help identify fossils found throughout Ohio, designed for use by beginners to professionals
Most land in Ohio is private property. Always obtain permission before collecting fossils. Most public lands (local, state, or federal) do not permit fossil collecting, except in designated areas.
Fossils and Fossil Hunting in Ohio
Once covered by vast tropical seas and later by giant glaciers, Ohio's landscape features an abundance of fossils. The glaciated portions of Ohio are home to Ice Age fossils, including plants and ancient mammals. But southwestern and northwestern Ohio boast a wider variety of much older marine fossils, including the official state fossil Isotelus maximus. In fact, the greater Cincinnati region lures paleontologists, fossil collectors, and rock hounds from all across the country and beyond who seek and have discovered some of the best fossil specimens in the world.
Public Sites in Southwest Ohio - Visitors should contact park management staff prior to collecting to obtain any permits and/or rules that may apply.

What are the oldest fossils?
The earliest evidence of life on earth is of marine animals, during the Precambrian era. But there is only sparse evidence of life before the Cambrian era. The oldest known Precambrian rocks, found in Africa and Australia, are believed to be more than three billion years old. The fossils found among them are of the oldest known organisms on earth. Usually, fossils found in these old rocks are microfossils, such as elongated bacteria, Eobacterium and other water environment fossils. Bacteria represents the first stage of recognizable organized life and scientists have found well defined remains of algae and bacteria from nearly two billion years ago.
Where are most fossils found?
The most common fossils are found in sedimentary rock. Sedimentary layers act as evidence of the changing climate or movement of the continents during the passage of time. The Law of Superposition or Steno's law states that in a pile of undisturbed sedimentary rock, the oldest bed will lie at the bottom and the youngest on top. Layers of strata in different locations may have the same composition but carry fossils of a different time period, therefore a technique of zoning or an index fossil is used. Index fossils are specific animals or plants that had a broad geographical distribution but existed for relatively short periods of time. These fossils allow geologists to establish a parallel between layers of sediment. Some excellent guide fossils are ammonites; each species lived for relatively short periods of time but had such a broad geographical distribution. They can be found today in stratigraphic rock layers often separated by great distances. The appearance of the same ammonite in different layers in different localities gives evidence that those layers were deposited at the same time. Each time period is marked by an abundant radiation of many new life forms or the mass extinction of past life forms.
"Many world-famous paleontologists—geologists who study fossils—began their careers as youngsters collecting fossils in their native Ohio. Fossils from Ohio are important constituents of museum collections throughout the United States and Europe." - Fossils Collecting in Ohio ODNR GeoFacts
As previously conveyed, "Fossils" are the remains of an ancient organism or the traces of activity of such an organism. There are two types of fossils: body fossils and trace fossils. Body fossils include preserved remains of an organism (i.e. freezing, drying, petrification, permineralization, bacteria and algea). Trace fossils are the indirect signs of life that give evidence of the organism's presence (i.e. footprints, burrows, trails & other evidence of life processes). www.ucmp.berkeley.edu/paleo/fossils/index.html
What are cast and mold fossils?
Casts and molds are types of fossilization where the physical characteristics of organisms are impressed onto rocks, especially coarse porous rocks such as sandstones. Typically, the hard parts of an organism ( shells of mollusks, skeletal structures of coelenterates, bones and teeth of vertebrate, chitinous exoskeleton of arthropods, trunks of trees, and many sphenophyte ) leave the best impressions. These hard structures are usually composed of calcium carbonate, calcium phosphate, silica, or chitin, and do not decay as easily. The rigidity of the hard body parts also allows the sediment to form around the organism. Soft body parts decay too fast for impressions to form and are not rigid enough for a mold to set around.
The fossilization process begins when the whole organism or hard body part is trapped in sediments. Because most of these body parts are typically composed of substances which are soluble in carbonated water, this entrapment usually occurs in coarse and porous rock such as sandstones. The porous nature of the rock enables the carbonated ground water to permeate and dissolve the original tissue leaving a detailed mold of the organism.
Two types of molds result from this process: external and internal. An external mold is created with the dissolution of the organic which then leaves an empty cavity imprinted with the external details of the organism. An internal mold may form with hollow structures. The "shell" of the organism is filled with various inorganic materials such as sediment or crystals. When the shell dissolves, it leaves an impression of the interior surface of the shells (e.g., muscle scars) on the material.
A cast of the organism can then be made using the two types of molds. Natural casts are formed when minerals are deposited within the mold. Casts can also be synthetically created when the molds are filled or covered with synthetic material, such as latex or plaster of paris, to generate a replica of the organism. In this manner, cast and mold fossilization enables us to "recreate" the structure of the organism. However in the creation of the cast, some details of the skeletal structures are lost.
BRACHIOPODS (Figure 1) “Lampshells” are sea animals with hard shells that were hinged at the rear. The Flood ripped the shells apart, burying piles of them in slabs of limestone.
BRYOZOANS (Figure 2) “Lace corals” were colonies of sea animals that lived together in connected modules, called zooids. The Flood tore apart these colonies, leaving only piles of broken “stems” and “branches.”
CRINOIDS (Figure 3) “Sea lilies” were animals that attached to the seafloor on long columns. The Flood tore apart their bodies, leaving only piles of broken pieces of the stems, called “columnals.”
Types of Fossils:
Fossils undergo a variety of different fossilization processes, depending on the characteristics of the particular organism. There are various levels of fossil preservation, each containing its own clues pertaining to the organism. Fossilization at the cellular level varies in all organic compounds since not all cellular types are equally resistant to decay and decomposition. The same hold at the tissue level, where some tissue types are more susceptible to fossilization. The other two kinds include the organ level and organism level which provide information in the field of morphology and biology of the ancient organism. Although there are an endless number of categories, we will focus on the broader mode of classification.
Permineralization: is the occurrence of decay of organic substances and filling of mineral material into every cavity of the organism, still retaining most information about the fossil.

How are fossils found?
There are certain techniques that paleontologists might exercise to find fossils, but it mostly has to do with chance and luck. However, all paleontologists need a place to start. Paleontologists must have an extensive knowledge of the stromatolites, the different eras, and which environment was most suitable for certain organisms. With this information, a collector can eliminate certain localities in his or her search. For example, if a collector was interested in finding fossils of animals of ancient rocky shores, he or she would eliminate formations and beds in which remains are likely to be rare and poor. Paleontologists can also follow leads that other paleontologists or collectors have left behind in published reports. These clues help narrow the focus of the search. For example, marsh plants are most abundant in shales and sandstones between beds of coal, and coals are found in limy shales and massive limestones, many of which are the remains of ancient reefs. Using these techniques, the process of elimination, and perhaps some luck, paleontologists have retrieved many different fossils and animal remains from a variety of geological areas.
Conditions that lead to fossilization:
There are many conditions that contribute to the formation of fossils. The most common include the possession of hard parts, such as a skeleton or shell, and a rapid burial after death. Besides being tough and hard, the organism must come to rest in a place where it can be buried before it decays or disintegrates. If the organism is not buried deeply and quickly, aerobic bacteria will reduce it to rubble. Water, given enough time, can also dissolve it. For this reason, fossils of some organisms are more rare than others. The skeletons that contain a high percentage of mineral matter are most readily preserved. The soft tissue that is not intimately connected with skeletal parts is least likely to be preserved. Other conditions that lead to fossilization include resting an environment that was biologically inert, areas that are receiving a large, steady supply of sediment (deltas of major rivers), and parts of the earth below sea level compared to those above the sea level. The ideal place to become a fossil is at the bottom of a quiet sea or lake where the prospective fossil is safe from damage and can be covered rapidly with sediment. Clay offers excellent conditions where the sediment protects the tissues and helps to exclude predators and solvent water.
Trammel Fossil Park - "A Rocking Good Time"
"The Corryville Formation is named after the Corryville neighborhood of Cincinnati, near the University of Cincinnati. Fine particles settling out of the seas formed the shale layers that you see in the Corryville. These fine particles resulted from erosion and runoff from the uplifted Appalachian Mountains, east of this region. From the Corryville shale, some of the most rate fossils have been found. In many other local areas, the soft shale has eroded away. Trammel Park is unique in that the Corryville Formation is exposed and undisturbed."- http://local.aaca.org/siraaca/Fossils.htm
What do fossils tell us?
"Different fossils, depending upon how they were preserved, tell us different things. For example, fossils that are preserved in amber give us an extraordinary amount of information about the anatomy of that organism; since the organisms that are preserved in amber, mostly insects, are usually preserved intact without any disintegration of organs, muscles, and coloring. Even bones may tell a great deal about the soft anatomy. For instance, the area where the muscle attaches to the bone leaves marks that indicate size, shape, and functions of these varied organs. Also, the cavities and the the channels in skulls give us an idea of their intelligence, behavior, and their principle features. Certain parts of certain fossils can also tell us about growth, injury, disease, form, function, activities, and instincts. Fossils also record the successive evolutionary diversification of living things, the successive colonization of habitats, and the development of increasingly complex organic communities. Fossils can tell a great deal about their surroundings and the conditions under which they lived. Finally, study of fossils contributes greatly to the study of evolution. They are the only direct record of what has occurred in sequences of reproducing populations and in the course of the time on an evolutionary scale."
Trilobites are a group of extinct arthropods (similar to crustaceans) with a hard shell. They are common in Ordovician rocks in the Cincinnati Arch. Unfortunately, almost all are fragments. Occasionally whole ones are found. The whole trilobites are usually found enrolled. There are over a dozen trilobites found in this strata. The most common two are Flexicalymene and Isotelus.
"This is a typical flexicalymene retrorsa minuens trilobite fossil that can be found at Caesar Creek. Flexicalymene trilobites in the Caesar Creek area are reduced in size and most often found enrolled. They are usually the size of a fingernail or smaller. When searching for them, they superficially look like tiny brachiopods, so take your time, look closely, and you may find one!"
Bryozoans are tiny colonial organisms, often mistaken for corals. The individual bryozoan is usually less than 1 mm in size. Bryozoan colonies can be branching, twiglike, fan-like, or encrusting. The entire colony is referred to as a zoarium. Some bryozoan colonies are smooth and others have monticules or bumps covering them. Each small opening or aperture was the home for an individual bryozoan or zooecium. The small animal seals the hole with a “door” or vestibule. They are difficult to identify without microscopic study. Sometimes the pattern of the apertures, size, or shape is characteristic and can be used for generic identification.
Brachiopods are marine animals that have a shell made of two valves, which usually differ in shape and size. Brachiopods are closely related to the bryozoans. Brachiopod comes from Latin and means "arm" + "foot" and bryzoan means "moss animal"
Brachiopods are solitary marine organisms that live between two valves or “shells.” They are very common in the Cincinnatian rocks of Ohio. They are externally different from the pelecypods (clams) in that the left and right halves of the brachiopod shells are usually mirror images of each other (see picture below). Internally, brachiopods are completely different from the pelecypods. Brachiopods feed with a special filtering organ called the lophophore which is located between the valves and attached to the brachial valve. The pedicle extends through a small opening or hole in the pedicle valve and is used as an anchoring device. The interior of the brachial valve is important in taxonomic differences between various species.
Crinoids are echinoderms that live on a long stalk, or column. Their crown is similar to an upside down starfish. Cross sections of the column usually have a tiny star within them. Columns and columnals are the most common parts found, although occasionally a crown or calyx can be found. It is rare to find the entire crinoid preserved. Crinoids are classified taxonomically by the characteristics of their crown, which makes identification of individual columns and columnals difficult unless the crown is attached.
Crinoids are a sort of sea lily, an animal which attaches itself to the ocean floor, has a columnar stem and a flowery type of head. Crinoid comes from a Latin phrase that means "like a lily"
The gastropods, or snails, are extremely diverse inhabiting marine, fresh water and terrestrial environments. Their shell can coil in a conical (conispiral) or in in single plane (planispiral).
Cephalopods are members of the phylum Mollusca and include squid, octopi and the pearly nautilus. Cincinnatian cephalopods were straight shelled squids. The siphuncle connects the cameras (chambers) together. The squid could pass air to the chambers via the siphuncle to make it float higher in the water or sink as it swam.
Phylum Cnidaria contains the corals, jellyfish, and anemones. Corals can be solitary or colonial. Corals have a rich fossil record because they excreted a hard calcium carbonate exoskeleton that preserves well. The Cincinnatian solitary corals are quite large, and are “horn” or “tooth” shaped. Individuals in the colonial corals are usually quite small, coralites being 1-3 mm in diameter.
Fossils of preserved remains can be:
Trace fossils are evidence left of past animal behavior. Some examples include:
Index fossils (sometimes called guide fossils) are a special category of fossils that only occur in a specific location(s), therefore are often used to identify and define specific geologic periods (or faunal stages).
What is Amber?
Amber is fossilized resin of a coniferous tree of early Tertiary. One of the differences between resin and sap is the latter's solubility in water since most of it is water from the xylem (water transporting system) of the tree.
In this type of fossilization, the organism is entrapped in a biologically inert environment and preserved as a whole. Intact insects are often found in amber, though they may be altered slightly. Many physical and chemical agents of abiotic environment (the oxidative air and temperature) and biotic factors (bacteria and scavengers) accelerate the decomposition of a dead organism. Avoidance of these factors aids in preserving the organism and in the amber formation.
The Process of Amber Formation:
Organisms fall or drop into the resin when it first exudes out of the tree. Essential oils, called Oleoresins, compose most of the first deposited resin. This substance is volatile and is often lost through the years. Additional resin then falls on top and gives the organism its typical suspended appearance. The resin then hardens through a process called polymerization and becomes less vulnerable to destruction. This hardened resin, called copal, has a higher chance of being fossilized than pliable resin.
As the copal ages, concentration of the essential oil decreases while the copal progressively oxidizes the resin and polymerization continues. The copal slowly turns into amber millions of years after the first entombment of the organism. The only way to differentiate between the two elements would be to put them through many physical and chemical tests such as UV light testing, burning, and various other tests.
The most famous examples of amber have come from the Baltic Sea region (Germany, Poland, Lithuania, Denmark, the former Soviet Union, Great Britain, Estonia, Latvia, and Holland). Because of the presence of microscopic air bubbles, Baltic amber tends to appear cloudy or milky. The hue varies with quantity and quality of the bubbles.

The Apple and The Earth:
Carefully peel an apple in quarters (4/4).
In comparison, three-fourths (3/4) of the apple represents the amount of water on Earth and one-fourth (1/4) represents Earth's total land surface.
Yet, one-eighth (1/8) of this slice of land is "Uninhabitable and Non-Arable Land" - approx. 1/8 of the Earth's surface is inhospitable to people and to crops. This includes areas such as polar regions, deserts, swamps, and high or rocky mountains.
The other one-eighth (1/8) represents one-half (1/2) of Earth's surface in which people live, but cannot necessarily grow food.
If this one-eighth (1/8) of the apple is sliced into 4 even cross-sections, consider that three out of thirty-two (3/32) slices represent land in which people can live but cannot grow food. "Some of it use to be arable, but isn't any longer because it has been developed or turned into cities, suburbs, highways, etc., so it can no longer be formed. Governments have earmarked other areas, such as parks, nature preserves and other public lands to remain undeveloped forever".
This leaves 1/32 remaining, which we will call our "most valuable part" - our "topsoil". Topsoil is our dark nutrient-rich soil that holds moisture and feeds us by feeding our crops. "Currently, 90% of U.S. croplands lose soil above the 'sustainable rate'."
Some Facts About Farmland:
"Erosion by wind and water is the most serious cause of soil loss and degradation. Although it is a natural process, erosion is accelerated greatly by things like construction, deforestation, and unsustainable practices in farming and animal grazing.
In the U.S., soil is now eroding at 17 times the rate at which it forms (via 2014). The soil erosion rate is estimated to be double in Asia, Africa, and South America. In order to feed the nearly 80 million humans added to the population annually, 12 million acres of new land must be put into production.
More than 25 million acres of productive arable land are severely degraded and abandoned worldwide every year—that’s an area the size of the states of Ohio, Indiana, Illinois, Michigan, Wisconsin, and Minnesota put together."
How can we preserve farmland?
By not building on arable land: Land covered up by buildings, highways, and other forms of development can't be used for growing crops. In the U.S., nearly 2.2 million acres of land are converted to urban and other uses each year. About 25% of that land is former cropland.
By eating lower on the food chain: While over a billion people suffer from malnutrition or starvation, meat production requires a disproportionate amount of grain input. Producing a pound of beef in a feed lot requires seven pounds of grain, a pound of pork requires four, and a pound of poultry requires two pounds of grain. The land that is used to produce grain for consumption by animals is unavailable for growing grain for human consumption.
By reducing pollution: Pollution impairs the ability of the land and the seas to provide food that's both sufficient in quantity and free of contaminants.
By stabilizing human population growth: Food supply is an excellent example of the relationship between any resource and the size and consumption patterns of the population that depends on it. Simply put, the more people there are to feed, the less food there is to go around.
