How can ground pollutants affect the local fresh water supply?

• The chemicals evaporate underground and come back in the rain water, filling lakes and rivers with toxic chemicals.

• Erosion of soil causes those chemicals to leak into the ground water supply and end up in lakes and rivers

• The chemicals absorb down their concentration gradient and eventually move to lakes and rivers

• When plants are harvested the soil and excess plant parts are dumped into the water supply

When certain chemicals such as CFC (chlorofluorocarbons) react with Ozone (O3), ozone breaks down to O2 (oxygen gas). Why would this have a negative impact on the climate?

• More oxygen causes more storms

• More oxygen in the atmosphere increases plant growth

• Ozone is part of what protects us from harmful UV radiation.

• More oxygen leads to increased human overpopulation and desertification

Which of the following is most likely to cause desertification?

• Cows digesting plants and releasing methane to break down ozone

• Lack of vegetation causing increased soil erosion, which displaces water from a region

• greater human population in a region causing flooding

• More traffic in a soil rich region would kick up dust clouds which cause lightning storms
