Question

Quizplus · Accepted Answer

Burning fossil fuels, such as coal, oil, and gas, releases carbon dioxide into the atmosphere. This process is the primary source of carbon dioxide emissions, contributing to climate change. While deforestation and rotting plant debris can also release carbon dioxide, their contribution is far less significant compared to burning fossil fuels. Animals also exhale carbon dioxide as a byproduct of respiration, but their emissions are considered part of the natural carbon cycle and are not considered a primary source of emissions.
