Question

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

Explanation:

Solar and hydroelectric power are low-carbon renewable energy sources that do not produce human-generated CO₂. Photosynthesis is a natural process that absorbs CO₂, not releases it. Burning fossil fuels (like coal, oil, and natural gas) for energy, transportation, and industry is the largest human-caused source of atmospheric carbon dioxide.

Answer:

burning fossil fuels
