Her mother bequeathed to her a life-long love of nature and the living world that Rachel expressed first as a writer and later as a student of marine biology. Carson graduated from Pennsylvania College for Women (now Chatham University) in 1929, studied at the Woods Hole Marine Biological Laboratory, and received her MA in zoology from Johns Hopkins University in 1932.

She was hired by the U.S. Bureau of Fisheries to write radio scripts during the Depression and supplemented her income writing feature articles on natural history for the Baltimore Sun. She began a fifteen-year career in the federal service as a scientist and editor in 1936 and rose to become Editor-in-Chief of all publications for the U. S. Fish and Wildlife Service.

Rachel spent a lot of time and effort to show the public that misusing pesticides can damage the environment and have long term effects. ]]> 2017-01-16 20:41:55 UTC https://padlet.com/bbuttram/xul9ht1r0x2u/wish/147416101 Why was preserving the environment so important to Rachel? 2017ejohnson https://padlet.com/bbuttram/xul9ht1r0x2u/wish/147416845 2017-01-16 20:48:52 UTC https://padlet.com/bbuttram/xul9ht1r0x2u/wish/147416845 The pesticide they were spraying, DDT, was originally used by the military in WW II to control malaria, typhus, body lice, and bubonic plague. DDT is still used in South America, Africa, and Asia for this purpose. 2020kgrogan https://padlet.com/bbuttram/xul9ht1r0x2u/wish/147677360 http://npic.orst.edu/factsheets/ddtgen.pdf]]> 2017-01-17 20:37:30 UTC https://padlet.com/bbuttram/xul9ht1r0x2u/wish/147677360 What is DDT? 2020bblevins https://padlet.com/bbuttram/xul9ht1r0x2u/wish/147678645 DDT or Dichloro-Diphenyl-Trichloro  is a synthetic pesticide that was used to kill bugs, but DDT killed more than just bugs, it killed many types of birds and animals that were higher on the food chain. After the side effects were noticed DDT was banned in many different states and countries

People started noticing dead robins around town and on college campuses. The manufacturers that made the pesticides reassured the people that the pesticide that was being used was harmless to birds. Clearly, that turned out to not be true. Several facts suggested that robins were also being poisoned, not even by the pesticides as much, but by eating the earthworms.   ]]> 2017-01-17 20:43:53 UTC https://padlet.com/bbuttram/xul9ht1r0x2u/wish/147678780 DDT is highly persistent in the environment.

Similar indications of the dying out of the race come from the world’s only sanctuary for eagles alone, Mount Johnson Island in the Susquehanna River. The island, although only 8 miles above Conowingo Dam and about half a mile out from the Lancaster County shore, retains its primitive wildness. 2019tlangford https://padlet.com/bbuttram/xul9ht1r0x2u/wish/147681522 2017-01-17 20:53:34 UTC https://padlet.com/bbuttram/xul9ht1r0x2u/wish/147681522
