Question

what is the main source of human - generated carbon dioxide in the atmosphere? (1 point) using solar power using hydroelectric power photosynthesis burning fossil fuels

Explanation:

Solar and hydroelectric power are renewable, low-carbon energy sources that do not produce significant CO₂. Photosynthesis absorbs CO₂ from the atmosphere, rather than releasing it. Burning fossil fuels (coal, oil, natural gas) releases stored carbon as CO₂, which is the largest human-caused source of atmospheric carbon dioxide.

Answer:

burning fossil fuels
