I've been using Ecosia for over a year now. Took about a week to get used to but I'm getting good results and if they actually do what they promise I'm doing something good for the world :)

I'm having trouble finding it on their website but I watched a regenerative agricultural guy two days ago say ecosia was giving out grants to people like himself. He had a permanent polyculture of mostly food, not trees, but it was neat.

I didn't know about this - thanks!
