Which of the following is the best example of a way human lifestyles affect environmental systems? (2 points) using radioactive materials causes ground pollution as it causes methane to seep into the ground. burning fossil fuels causes water pollution by decreasing the amount of water vapor in the atmosphere. deforestation causes acid rain by decreasing carbon dioxide (co2) in the atmosphere. using aerosols that contain chlorofluorocarbons (cfcs) decreases the amount of protective ozone (o3).

The correct answer is option Using aerosols that contain chlorofluorocarbons (CFCs) decreases the amount of protective ozone (O3).

The aerosols, which contain CFCs or chlorofluorocarbons can cause the depletion of the ozone layer. The CFCs can get dissolved in the atmosphere and react with the ozone, which causes the depletion of the ozone molecules in the oxygen molecules. The ozone is the protective layer, which prevent the UV rays coming from the sun to enter in the atmosphere of the earth.
