Coming from a person that also believes in conservation efforts I find I get more interaction with my posts If your can tie both crypto and conservation together like CO2 coin or this neat game from google play which from what I can tell is actually both paying users crypto (I have withdrawn crypto this parts real) and allows users to contribute to conservation efforts such as amazon rainforest conservation ocean clean up, Energy alternatives research and much more. This seems to be legitimate from what I could tell from their website and the conservation groups they mention are real.

This is something small that helps the planet, like some of the small life changes you suggested its a way to make watching ads for a faucet something many in the crypto circle do already also help the planet a little to. I wont include a referral unless you want one the game is called Green Karma on play store made by Phoneum ( could not picked a worse name but check them out before you dismiss them)

Nice to see someone else who cares about the planet have such a High earning article
