Question

what is the problem with fossil fuels?
the amount of land required is large, and they are nonrenewable.
they are expensive to process and cause significant environmental damage.
extraction and use cause environmental damage, and depletion is likely.
they are renewable and cause greenhouse gas production.

Explanation:

Fossil fuels are nonrenewable, so their depletion is inevitable with continued use. Their extraction (e.g., mining, drilling) and combustion (releasing greenhouse gases, pollutants) cause significant environmental harm. Other options are incorrect: large land use is not a primary issue, they are not expensive to process relative to some alternatives, and they are not renewable.

Answer:

Extraction and use cause environmental damage, and depletion is likely.
