Hello this is Your Opinion speaking here,and I think you should plant some trees or donate.You may think that a tree is expensive,but if you donate to Mr.Beast it's one dollar each tree.Mr.Beast has planted 15 million trees so far,but the goal is 20 million trees.You can search #teamtrees in Google and YouTube.Trees can stop pollution and can be relaxing and calming to be around,and these new trees can be new homes to animals and  new food.So planting a couple of trees can save everyone.
