On April 26, 1996 the fourth reactor of the Chernobyl power plant surged and exploded, spilling tens of tons of radioactivity into the atmosphere. As the operators decided to run the reactor on low power, the cooling system failed and the temperature soared, bursting pipes and exposing the core to the environment. As the cloud of radiation spread across the majority of Europe the affect of the explosion became extremely harmful. As the initial explosion took place, two workers were killed and in the following days multiple more workers died of acute radiation sickness. A total of close to 500,000 people were evacuated from the surrounding area in attempt to save them from the dangers of radiation. Contamination to human food sources and also to the large areas of pasture around the site would become a major issue to people of the soviet union. Though management was set in place to regulate the contamination, not enough caution was taken. Over 6,000 cases of thyroid cancer are linked directly to Chernobyl and the analyzation of the entire affect is still ongoing. The explosion has also taken a toll on the environment. It is known as the "Zone of Alienation" and humans are not permitted access to the grounds. Everything within a large radius of the plant is highly radioactive and the area will not be compatible for human settlement for at least another 20,000 years. However, the woodland just outside the "Zone of Alienation" is home to some of the most unique and diverse wildlife on Earth.

The Cuyahoga river was once a filthy river contaminated from top to bottom of the river. Not until the national environmental act was passed. There have been 13 river fires from the date of 1868 to 1969. Due to the factories located near the river and dumping all of its wastes into the river it had created a oil layer in the top of the river cause it to get in flamed when trains would pass by. They only decided to pass the act in January 1 1970 after the last river fire. But it was through lots of effort they decided to keep the river clean. From the very first river fire in 1868 to the 1912 where they had a toll of five deaths and the 1952 where the cost to repair everything was up to 1.5 million dollars. After the river was completely dead in 1960 where there was only 2 species of fish left in the river they still decided to keep the river as is. But the 13th river fire the 1969 was the game changer. The fire reaching height of 5 stories after putting out the flames they decide to clean thee river. wasting billions of dollar to purify the river and now up to 60 new species of fish now live in the river.

Donora Pennsylvania was hit by a smog on October 26 in 1948. The smog was caused by the smelting of zinc and melting of metals from plants.The people of Donora Pennsylvania were hit with a fog that trapped the pollutants from the zinc causing a thick white cloud which looked like fog. Soon after the 14,000 resident felt the effects of the smog. People with Pre-existing health conditions, mostly old people, started to die. People of Donora were in a panic trying to evacuate but was unsuccessful because of the smog being to thick for people to drive.Zinc works the company running the smelting plants in Donora finally decided to shut down the plants, this was a smart move because it improved the conditions. The Donora smog incident revived national news coverage people are more aware of air pollution in the United states. This also lead to the United States passing an act called the clean air act of 1955 which gave government funding to the research of air pollution in the U.S.A.

Glacier National Park
The Glacier National Park is located in the state of Montana near the United States-Canada border. Glacier National Park was founded on May 11, 1910 and has since been home to various types of wildlife. The park covers more than 1 million acres of land and includes two mountain ranges, more than 100 lakes, over 1,000 species of plants, and hundreds of animals throughout the entire park. Some of the plants that can be found include the subalpine fir, the purple aster, the moonwort fern, the rock harlequin, and more. Animals such as the bald eagle, the pygmy shrew, the Clark's nutcracker, and the long-toed salamander can also be found roaming around. Most plants throughout the park are described as annual or biennial plants species, meaning that they live up to one or two years. This is due to the fact that plants find it very hard to adapt to its surrounding, specifically the weather. The weather at this location is very unpredictable, during the summers it can get above ninety degrees Fahrenheit and at night it can get get as low as twenty degrees. If you go higher up the mountains it tends to get a bit chillier due to the wind, and so temperatures tend to be at least 10 degrees cooler. This park also contains numerous ecosystems ranging from tundra to prairie.

Yosemite National Park was established in 1890 which was home to the
Ahwahneechee people for thousands of years before settlers arrived in the area. Yosemite National Park is
United States national park lying between Western Sierra of Northern California. Almost 95% of the park of the is classified as wilderness. Yosemite National Park offers an abundance of activities and sightseeing destinations. Yosemite is known for its Waterfalls which includes Yosemite Falls the largest waterfall in North America. Yosemite National Park supports more than 400 species of vertebrates including fish, amphibians, reptiles, birds, and mammals.Three species: grizzly bear, California red legged frog, and foothill yellow legged frog are believed to be extirpated in the park within recent history. An astounding 262 species of birds have been documented in Yosemite. Two Mammals that are being protected from being threatened at Yosemite include the Sierra Nevada Red Fox and the Wolverine.

The Great Pacific Garbage Patch is a body of marine debris and broken down plastic particles concentrated in the centre of the North Pacific Gyre. Also known as the Pacific Trash Vortex, it spans from the West Coast of North America to Japan and is a collection of the Western Garbage Patch closer to Japan and the Eastern Garbage Patch closer to America. Research shows that about 80% of this debris is land-based, 65% of which, is plastic that hasn’t been disposed of properly. Carelessly discarded plastics and other garbages makes its way into the ocean by wind, streams or rivers. Another contributor to this disaster is cargo and passenger ships. Ships lose cargo due to storms and it makes its way into the gyre. The ocean’s currents traps the debris in the center of the gyre, creating what could be perceived as an island of disposable plastic and other types of debris. Its estimated size is said to be twice that of Texas. It has been in existence for over fifty years and in that time, over one million pounds of garbage has been accumulated.
Not only is it an unpleasant sight, marine debris is harmful to marine life. Loggerhead turtles often mistake plastic bags for jellies and can choke on it. Albatrosses mistake plastic resin pellets for eggs and feeds it to their young ones. This causes the birds to die of starvation and/or disruptured organs. The garbage blocks out sunlight from the ocean’s autotrophs that depend on it for food. This then changes the food web and as a result, seafood populations slowly deplete and as seafood becomes scarce, it also becomes expensive. In an effort to clean the mess we’ve made and rid the ocean of this disease, eliminating or limiting our use of disposable plastic and switching to biodegradable resources would be a fantastic start. Throwing away our garbage in the appropriate bins is also another way to help. Recycle and Reuse while there is still have time to choose if we win or lose.
