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.

​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/

​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".

Starry Night:  ​The Milky Way glows in the sky over a geologic formation known as Monument Rocks in Gove County, Kansas. The Milky Way is best viewed on moonless summer nights, far from the light pollution created by cities and towns.  Astronomers believe our galaxy contains about 200 billion stars.

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

​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.

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.

Green Umbrella’s Local Food Action Team (LFAT) is working to strengthen our regional food system by encouraging all consumers to take the 10% Shift: Eat Local Challenge.

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.

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.

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.

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.

• Compressions: the two-dimensional compression which retains organic matter of the organism.
• Impressions: the two-dimensional imprint most commonly found in silt or clay, without organic material present.
• Casts & Molds: caused by deposits of sediment in cavities of organism, resulting in a three dimensional model.
• Compactions: preservation of organic material with slight volume reduction.
• Molecular fossils: deals with chemical data, preserving organic material, but providing no information concerning the structure of the organism.
• Freezing: ideal fossils that are rare, everything up to internal organs are preserved in cold storage.
• Amber: biological specimen that is encased in the hardened resin of a tree, in which the entire body may be preserved.
• Drying & Desiccation: fossils that have been thoroughly dried.
• Wax & Asphalt: almost as good as freezing, but with the usage of natural paraffin.
• Coprolites & Gastroliths: these categories deal with the indigestable remnants of meals.
• Trace fossils: typically formed when an organism moves over the surface of soft sediment and leaves an impression of its movement behind.

​"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.

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.

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.

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.
