Yes because at some point we will have to face the fact that the environment is changing and some kind of action has to be taken for the sake of our health and our children.
Without a healthy environment we wouldn't be able to make the most out of the cryptocurrencies we have right now. Imagine a Fallout-like scenario where they use bottle caps as modes of payment. That could be our inevitable fate come the day that our planet give up on us. Everything we have invested for will be for naught and the worst is it's our children and grandchildren who will suffer from an unbearable environment. So I don't mind throwing in a few of my cryptos to fund movements that promote the environment's welfare.
