Unformatted text preview: acid rain with damaging effects: destruction or damage of foliage; great amounts of weathering of continental rocks; the upper ocean organisms are killed. These organisms are responsible for locking up carbon dioxide in their shells (calcium carbonate) that would eventually become limestone. However, the shells will dissolve in the acid water. That along with the "impact winter" (described below) kills off about 90% of all marine nanoplankton species. A majority of the free oxygen from photosynthesis on the Earth is made by nanoplankton. The ozone layer is destroyed by O 3 reacting with NO . The amount of ultraviolet light hitting the surface increases, killing small organisms and plants (key parts of the food chain). The NO 2 causes respiratory damage in larger animals. Harmful elements like Beryllium, Mercury, Thallium, etc. are let loose....
