Greenhouse gases are naturally occurring in the Earth's atmosphere and are needed to trap heat to keep the planet warm enough to support life. However, the increased levels of greenhouse gases due to human activities are leading to global warming and climate change, which have negative impacts on the environment and ecosystems. Balancing greenhouse gas levels is important for maintaining a stable and habitable climate on Earth.
