Emission refers to the release of substances, particularly gases, into the atmosphere. This process is a significant contributor to air pollution and climate change, as various emissions can trap heat in the atmosphere, leading to global warming. Common sources of emissions include vehicles, industrial processes, and agricultural activities. Efforts to reduce emissions are crucial for improving air quality and mitigating climate change. Strategies such as transitioning to renewable energy sources, enhancing energy efficiency, and implementing stricter regulations on pollutants can help decrease harmful emissions. Understanding and managing emissions is vital for a sustainable future.
