A combination of many dangers, with the main danger being the pesticide DDT, the bald eagle was on the verge of extinction. Yet, through conservation measure applied by the United States government the bald eagle cam back from the brink and was taken off of the endangered species list in 2007.
The main downfall of the bald eagle was the pesticide DDT. DDT otherwise known andichlorodiphenyltrichoorethane, would not dissolve in water or break down in the environment.

The Condor was then added to the endangered species list of the United States. Moreover, Condor comes under the category of critically endangered (CR) species which is the most severe category under conservation status subjected to species at the highest risk of extinction.

    “It is my conviction that killing under the cloak of war is nothing but an act of murder,” Albert Einstein. The Vietnam War was a war that America did not need. America believed they were doing good. They believed that they were protecting the people of Vietnam. America did not realise that they were only making a bad situation worse. America stopped nothing. They didn’t stop communism; they didn’t save the people of Vietnam. America caused the number of casualties in Vietnam to increase and had their own people killed. They caused diseases and destroyed the environment with the help of Agent Orange. America sent soldiers on a mission with a result of hundreds of civilians murdered. America did not help anyone.
