How can carbon dioxide be released into the atmosphere?

• A. By planting trees
• B. By burning fossil fuels
• C. By recycling plastic
• D. By using renewable energy sources

Answer: (B)

Releasing carbon dioxide into the atmosphere primarily occurs through processes that involve the combustion of carbon-based materials. Burning fossil fuels, such as coal, oil, and natural gas, is one of the significant sources of carbon dioxide emissions. When these fuels are burned for energy, whether in power plants, vehicles, or industrial processes, they react with oxygen in the atmosphere, resulting in carbon dioxide as a byproduct. This increase in atmospheric carbon dioxide contributes to the greenhouse effect and is a driving factor in climate change. In contrast, planting trees, recycling plastic, and using renewable energy sources are actions that help reduce or mitigate carbon emissions. Trees absorb carbon dioxide during photosynthesis, while recycling plastic reduces waste and the energy consumption associated with producing new materials. Renewable energy sources, such as wind, solar, and hydroelectric power, generate electricity without releasing carbon dioxide into the atmosphere, thus playing a crucial role in combating climate change.
