    Silent Spring is a book that Rachel Carson wrote in 1960 and was only the beginning of the environmental movement. During the same time there were many several major environmental events that were occurring. These environmental events include oil spills along southern California’s and Massachusetts coasts. Extinctions of many species were also taking place, for animals such as whales, song-birds, and elephants. James Lovelock was also an important individual in the 1960s. Lovelock came up with the Gia hypothesis. The Gia hypothesis proposes that the environment at the global level has been profoundly changed by life over the history of life on Earth and the changes tend to improve the chances for the continuation of life. Life of all shapes and sizes affects the environment at a global level, and the environment of our planet differs from a lifeless one.…

    I'm passionate about science, specifically the science that revolves around how our planet works. I live in an area that is a geological hot spot, I’m only miles away from Crater Lake and I live near the Cascadia Subduction Zone. I began to learn that earthquakes and natural disasters were a phenomenon that I wanted to learn more about. So I challenged myself by taking 4 and half years worth of science credits. My junior year I took Chemistry and Physics, and my senior year I continued building credit by taking AP Environmental Science. Each year I strived to earn good grades so that I could have an opportunity to continue my education. I want to earn a bachelor's degree in Earth Science and continue on to an advanced degree. My career goal…

Some is also released through lightning and forest fires.Carbon monoxide is formed by incomplete combustion of most matter. Vehicle exhaust and many other combustion process produce Carbon monoxide. It is also a indoor pollutant when exhaust systems on natural gas heaters misfunction. Carbon dioxide is produced from complete combustion of most matter such as biomass and fossil fuels. Particulate matter is released when fossil fuels and bio fuel is burned. Also it is released with activities that involve movement of dust or sand. Lead is released from old paint, gasoline additive and combustion of fossil fuels. Tropospheric ozone is a secondary pollutant and is made by water,sunlight,oxygen,nitrogen oxides and VOCs.…
