We need oxygen to breath without oxygen there will be no humans. Animal and wildlife need oxygen to grow. The world looks so much nice with trees. We don't want to have to buy oxygen in plastic bottles that are single use to survive. Do you ,well it's your choice and we only have one earth remember. Life will be better for our children and our grandchildren. Please understand this our fault and we need to make a change before it's too late.Maybe covid was a warning saying we need to get our act together before it's too late. Look I am one 16 year old girl trying to make a difference this is one of the reason I went vegan. Climate change will be so much worst not just different weather. Species will go extinct maybe we will. I don't know what the future holds but we can make a change and hopefully save our wonderful planet before it's too late. As this quote says " go green there is no planet b". Listen you old folk you might be gone  but we still need somewhere to live.If the sun was any further away we would burn. Closer to the moon we would freeze.There is no other solution, just listen to me and Greta Thungburg. We are right and we can not be quiet as we care about where we live. You should too and not blame others , please listen to me before it is too late.
