Question

which of the following is a way to mitigate global warming?
a. develop practical ways of dealing with the effects of climate change.
b. invest in alternative energy sources that do not burn fossil fuels.
c. invest in water sources that do not depend on climate.
d. identify crops that can be grown under different climate conditions.

Explanation:

Global warming is mainly caused by the emission of greenhouse gases, especially from burning fossil fuels. Mitigation focuses on reducing the root - cause emissions.

• Option A: Dealing with climate change effects is adaptation, not mitigation.
• Option B: Alternative energy sources (like solar, wind) that don't burn fossil fuels reduce greenhouse gas emissions, which is a mitigation strategy.
• Option C: Investing in water sources is more about water security and may be an adaptation measure (if related to climate - induced water scarcity), not mitigation.
• Option D: Identifying climate - resilient crops is an adaptation strategy for agriculture, not mitigation.

Answer:

B. Invest in alternative energy sources that do not burn fossil fuels.
