What I should do as a citizen to stop global warming

Regarding the recent years temperatures started to get extreme in the two opposite season “winter and summer”. While we noticed in this winter we had heavy rain that we didn’t used to have it before 10 years that’s one of the signs of global warming in my country .and now we are expecting that this summer will be hotter than the one before. So what can we do? As we all know that CO2 one of the elements that courses global warming, and there are some home machines that produce it for example air condition, So we need to use it less or replace it with another machine such as air fan. Another thing that we can do is to reduce the uses of cars and if the weather is nice we can use bicycle or take a walk. Moreover, when I go to carfour to buy bottles of water even plastic bags when I am done with them these things should be recycled instead of burn it.
