Planting trees is in the same category of solutions as recycling. In theory you could plant a quadrillion trees, but realistically it won’t happen and instead the initiative will be used as a way to increase our consumption and destruction of the planet even more.
Reduce, reuse and recycle was the original term. Everyone over indexed on recycling and completely abandoned the first two. (Instead we went the other way and started individually wrapping bananas in plastic)
