Question

Quizplus · Accepted Answer

Carbon dioxide is primarily released by the burning of fossil fuels such as coal, oil, and natural gas. Livestock also contribute to greenhouse gas emissions, particularly through the production of methane, but this is not the primary gas responsible for the greenhouse effect. Rising ocean temperatures and desertification can also contribute to greenhouse gas emissions, but they do not directly release carbon dioxide.
