6. Why are some greenhouse gases necessary?
1 answer
Some greenhouse gases, such as carbon dioxide and water vapor, are necessary because they help regulate the Earth's temperature by trapping heat in the atmosphere. This natural greenhouse effect is essential for maintaining a stable climate and allowing life to exist on Earth. Without these greenhouse gases, the Earth would be much colder and uninhabitable. However, human activities, such as burning fossil fuels, have contributed to an increase in greenhouse gas concentrations, leading to global warming and climate change. It is important to find a balance in greenhouse gas levels to maintain a healthy and sustainable environment.
