Humans and the Environment Unit EQ: How do human activities affect the physical and biological features of the earth? Diane Gioia – Bell’s Crossing Elementary
To Albert Schweitzer who said “Man has lost the capacity to foresee and to forestall. He will end by destroying the earth.”’ -Rachael Carson’s dedication in Silent Spring • “We are the most dangerous species of life on the planet, and every other species, even the earth itself, has cause to fear our power to exterminate. But we are also the only species which, when it chooses to do so, will go to great effort to save what it might destroy.” -Wallace Stegner • The earth does not belong to man; man belongs to the earth. This we know… All things are connected. Whatever befalls the earth befalls the sons of the earth. Man did not weave the web of life, he does to himself… This earth is precious to Him [the Creator], and to harm the earth is to heap contempt upon its creator. -Chief Seattle Suquamish Tribe 19th Century

Pollution • Making the environment unclean with wastes • Gases, chemicals, heat, garbage, and noise • Materials that cause pollution are pollutants
Air pollution • Caused by burning fuels and trash • Industries cause such pollution • Causes lung disease and acid rain
Water pollution • Industrial wastes, sewage, and chemicals dumped into water supply • http://streaming.discoveryeducation.com/search/assetDetail.cfm?guidAssetId=56CAE996-65EF-41CA-9B32-4BB2739AC5E9
