Time for change

I think we should all stand up to global warming and save our planet even "small changes add up" like you can ride your bike instead of taking your car or walking to the store that is nearby instead of using your car. Some people say why should we do anything? We are all going to die anyway but why not do something so all of our generations can have a good life, Why not do something to save our human kind, the animals, the plants and especially our earth.
