ANT101H5 Lecture Notes - Lecture 22: Habitat Destruction, Chlorofluorocarbon, Staphylococcus
Document Summary
The geological epoch during which human behavior became one of the earth"s major geomorphological and geological processes. Carbon dioxide (most destructive produced from non renewable fossil fuels) Sea ice reflects back into space about 80% of the sunlight that hits it. This will lead to the extinction of several species including polar bears who rely on sea ice for their survival. Others see melting sea ice as a financial opportunity increased sea transport and drilling for oil. Weather will increasingly become unpredictable and more extreme and destructive events. Coral reefs are the most diverse marine ecosystems on earth important food source. 20-25 % of animal protein consumed by humans comes from a marine environment. In the last 570 million years there have been at least 15 million extinction events, two of which altered all of the earth"s ecosystems. 1st 250 mya resulted from climate change merging of earth"s landmasses into one super-continent.
