Greenhouse gas emissions are gases that trap heat in the atmosphere, contributing to the greenhouse effect and global warming. The primary greenhouse gases include carbon dioxide, methane, and nitrous oxide, which are released through various human activities such as burning fossil fuels, deforestation, and industrial processes.
Reducing greenhouse gas emissions is crucial for mitigating climate change and its impacts on ecosystems and human health. Efforts to decrease these emissions involve transitioning to renewable energy sources, improving energy efficiency, and promoting sustainable practices in agriculture and transportation.
