Global warming is caused by the greenhouse effect. The main things that humans can do to decrease the impact of global warming in the future and now are to make sure that the things you do don’t harm the environment. Some of these things include stopping usage of aerosol cans which has decreased over time with companies using a spritz spray instead of aerosol. Second, you can recycle. Recycling can help reduce the greenhouse effect.
Third, plant a tree. When you plant a tree, oxygen is released from the tree and that will help the environment. Another thing you can do is to conserve electricity. When you conserve electricity, you are conserving energy. Finally, you can conserve electricity by using less heat and air from the air conditioning.
