Preview: ... ery physical, chemical or biological process generates some pollution and there is no way to avoid it. v We damage the atmosphere by releasing greenhouse gases, when we drive cars or use electricity. v We pollute water with chemicals and waste products from factories. What we attempt to do is find ways by changing our lifestyle to minimize the pollution. As we become more sophisticated and rich we learn how to do just that, today in theUSwe see cleaner air, cleaner water, micro-miniaturization, better packaging, sophisticated recycling and agricultural innovations. Ways that global warming might affect our ecosystems: Global warming refers to the risingaverage temperatureofEarth's atmosphere and oceans and its projected continuation. In the last 100 years, Earth's average surface temperature increased by about 0.8 °Celsius (1.4 °Fahrenheit) with about two thirds of the increase occurring over just the last three decades. Warming of theclimate systemis unequivocal, and scientists are more than 90% certain most of it is caused by increasing concentrations ofgreenhouse gasesproduced by human activities such asdeforestationand burningfossil fuel. These findings are recognized by the national science academies of all the major industrialized countries. There are two major effects of global warming: v Increase of temperature on the earth by about 3° to 5° C (5.4° to 9° Fahrenheit) by the year 2100. v Rise of sea levels by at least25 meters(82 feet) by the year 2100.
