Question

multiple choice 1 point
which factor contributes most to modern extinction rates?
genetic mutations
natural climate cycles
habitat destruction and climate change caused by humans
reduced solar energy

Explanation:

Human - caused habitat destruction (e.g., deforestation for agriculture, urbanization) and climate change (due to greenhouse gas emissions) disrupt ecosystems. Species lose living spaces and face altered environmental conditions (temperature, precipitation changes). Genetic mutations and natural climate cycles occur naturally but at slower, more manageable (historically) paces. Reduced solar energy is not a major modern - era extinction driver compared to human activities.

Answer:

Habitat destruction and climate change caused by humans
