how to help slow down and stop global warming

Hi my name is Joshua Smith and plan on spreading awareness to global warming because the more people know the more likely it will have substantial effect because if one person can get what 20, 30, 50, 100 people to help then how big of a effect will it be if 20 do it then 30 then 50 then 100 do because maybe at the start it may only get to so many people but that number will multiply quickly as other schools join in to take part in it and the radius of people that see it will increase as well as the number of creators then the question is how long would a effort like this would have to go until the media takes a large part which will bring it to so many more eyes making a far bigger effect and all that you would have to do is to spread the word and contribute to the cause by reducing even if it's just the little things it will add up quickly like driving less and cycling more and having a balanced diet both of which will help improve your life as well as helping to stop global warming because alone we can't do much but together we can do anything.
