Global warming is the biggest issue globally 
we as humans know that we are responsible for this then also there is not much change in our ways."we have not occupied the earth from our forefathers but we have borrowed it from our children".this is the best quote to support that global warming should be stopped . It causes so much harm to our environment that our earth will not have much time left.we shoul atleast think about our next generations or our children that how will they survive in those adverse conditions . we as humans should start taking care of our mother earth from this instance and pledge not to pollute our mother earth ever again.
