Which of the following is the best example of a way human lifestyles affect environmental systems? burning fossil fuels increases the amount of greenhouse gases in the atmosphere. using radioactive materials causes ground pollution when chlorofluorocarbons (cfcs) seep into the ground. deforestation causes water pollution by decreasing water vapor in nearby lakes and rivers. using aerosol sprays increases the amount of ozone (o3) in the atmosphere.

The correct answer is the first statement.

Explanation:

Coal, natural gases, oils, oil rigs, and fossil fuels were made millions of years ago. These fuels contain carbon that was present in the organisms and organic matters when they died, which is the original source of energy.

When we these fuels, it causes too much carbon release in the environment and atmosphere at once. The carbon forms carbon dioxide with oxygen, a greenhouse gas.

Greenhouse gases are responsible for global warming as they trap the Sun's energy in the atmosphere that leads to the rise in temperature.

Thus, the correct answer is the first statement.
