As has been known, greenhouse gases such as carbon dioxide, Freon gas and methane gas are affecting the causes of global warming. The Earth is getting hotter every year, and that's why it's causing a lot of weather changes. Therefore, we should try to reduce greenhouse gas emissions, and also make efforts to catch the gas that has already been released and turn it into another substance. I think there should be a lot of projects for the environment like HiveMind.
