The movie Silkwood was about a company that was producing dangerous chemicals such as plutonium. A woman by the the name of Karen Silkwood become aware of the unethical issues that were going on at the chemical plant she was working at. Being that the company knew they were producing chemicals that were harmful to the environment and the workers , which caused many of them to leave the plants or have the chemicals painfully scrubbed off of them. Karen Silkwood later died in a car accident.
In my opinion, these same issues arise in our society today with industrial companies that know their plant is producing harmful chemicals and they do not want to change their ways of production because of loss monetary gains. The movie was interesting I thought it goes to show how far environmental policies have come about due to media, grassroot movements, and governmental policies being implemented.

Mitochondrial Eve is defined as the woman who is the matrilineal most recent common ancestor for all living humans. It is believed that most of the ancestors of Mitochondrial Eve originated from the region of East Africa. This idea further confirms that all humans have some type of Mitochondrial DNA in their body. Mitochondrial Eve is thought to be a woman that lived in eastern Africa about 140,000 years ago. The concept is distinct from most recent common ancestor because the number of ancestors one has goes up exponentially as one travels back into time, the most recent shared common ancestor of all humanity lived more recently, probably less than 100,000 years ago. But due to sexual recombination of nuclear DNA, every living person today has only a fraction of shared genetic material with that common ancestor.

The organism I chose to do my ecological niche on is the beaver. In a beavers ecological niche, one might find trees branches, ponds , and other organisms (foxes, coyotes, and wolves) near wetlands. Beavers use the trees as a sources of nutrients while their dam building provides as a habit for other organisms in a niche; such as fish, frogs. and water plants. Overall, the ecological niche of a beaver is define as providing habitat for other animals through their dam building as well being prey for other animals.

The biome that I found to be the most interesting was the cold desert biome. The cold desert consist of species such as; jack rabbits, kangaroo rabbits, pocket mice, antelope, lizards, and coyotes. On average, the temperature for the cold desert located in Antarctica is between -2 and 4 degrees Celsius. During the summer the temperature shows very little change with temperatures being between 21-26 degrees Celsius. This biome also receives a bit snow, in the winter there can be as much as 15-26 amount of snow. I chose this biome because the desert is an interesting place to me and I have never heard of a "cold" desert.
