b) it uses renewable resources. reactivate c) it causes a hole in the ozone.
d) it increases the greenhouse effect.

The correct answer is D. It increases the greenhouse effect

Explanation

The greenhouse effect is a phenomenon whereby certain gases retain part of the energy emitted by the soil after being heated by solar radiation. There is, therefore, a heating effect similar to that occurring in a greenhouse, with an increase in temperature.

Although the greenhouse effect is produced by the action of several components of the planetary atmosphere, the heating process has been accentuated in recent decades by the action of man, with the emission of carbon dioxide, methane, and other gases, produced by the combustion of fossil fuels such as oil and gas. so, a negative effect of the combustion of fossil fuels is that it increases the greenhouse effect. So, the correct answer is D. It increases the greenhouse effect
