There's actually (or was?) A kind of equivalent right here on steemit. I heard it was legit but that was the last I heard of it... doesn't exactly have billions of dollars behind it though =/
If you're bored though you could make rice online: http://freerice.com/category
I know of @treeplanter. But stopped using it for myself, as I was scared it counts as upvote bot and would interfer with steemstem curation...
But I will check out how convenient freerice.com is on mobile devices. Definitely something interesting to cklick around on at a bus stop.
You mean the one that made comments that were shaped like trees? I liked the idea, but never knew whether it could be verified as real or not.
Yeah you guys have a better memory than me. Maybe we can combine alipay tree planting with steemit somehow...
I did my part by planting @dysprosium's peppers )
