which factor contributes most to modern extinction rates?
genetic mutations
habitat destruction and climate change caused by humans
reduced solar energy
natural climate cycles

Explanation:

Human - caused habitat destruction and climate change have a significant impact on modern extinction rates. Genetic mutations are a natural process that occurs over long periods and do not contribute as much to modern extinction rates. Reduced solar energy is not a major factor in modern extinction rates. Natural climate cycles also occur over long periods and do not contribute as much to modern extinction rates as human - caused factors.

Answer:

Habitat destruction and climate change caused by humans
