The environment has being degraded in many ways. According to the CIA World Factbook, our biggest issues include 1) pollution 2) loss of vegetation 3) loss of wildlife 4) soil deterioration and 5) global warming. Humans have caused much pollution, whether it be smog in the air, garbage in the water, acid rain, or toxic substances. We have eliminated vegetation through overgrazing of livestock, deforestation, and desertification. Animals have gone extinct or become endangered due to overhunting, poaching, and habitat destruction. We have degraded, depleted, and eroded soil, making it unusable in some areas. And finally, by releasing greenhouse gases, we have contributed to global warming.
