Idea I had

Remember in 2014 when people were posting video’s of them emptying a bucket of ice over their head everywhere for ALS and people all around the world started doing it and nominating their friends? What if we started something similar, like for example someone plants a tree, posts pictures of it on social media and nominates their friends to do the same. The main excuse people have when you ask them why they don’t eat less meat or something like that is that one person isn’t going to save the world. This challenge fixes that problem, as planting just one tree and nominating your friends who in turn nominate other people can create a huge chain reaction. I’m just curious to know if something like this is doable and what you guys think about this idea.
