Explain the concept of greenhouse gas emissions.

Greenhouse gas emissions refer to the release of gases into the atmosphere that contribute to the greenhouse effect and global warming. These gases, such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), trap heat from the sun and prevent it from escaping back into space, leading to an increase in the Earth's temperature. The main sources of greenhouse gas emissions include burning fossil fuels for energy, deforestation, industrial processes, and agricultural activities. The excessive accumulation of greenhouse gases in the atmosphere is a major environmental concern as it leads to climate change and various adverse effects on ecosystems, weather patterns, and human health. Efforts are being made globally to reduce greenhouse gas emissions through measures like transitioning to renewable energy sources, improving energy efficiency, and implementing sustainable practices.
