Our Earths population is getting bigger and bigger everyday. More people being added means more CO2 is being added and that is a huge pollutant to our Earth. Every year three billion metric tons of CO2 are added to the atmosphere every year (“Global Climate Change” ). Pollution has increased atmospheric
