It's pretty meaningless when on the higher level you have multi billion dollar corporations bribing politicians so that this can happen. These politicians do not care because they live far away from where the fire is rapidly destroying more and more nature. All they have always cared about is to be corrupt. The whole country suffers from the leadership of these criminals.
It's not just corporations, small-scale farmers burn the forests too, and they don't even have to bribe politicians, because the current leadership of Brazil thinks that any environmental concerns are just communist propaganda or something. This is why some countries have actually pulled out their funds that were donated to prevent fires. So, this blockchain crypto charity will be absolutely useless, since it's a political problem first.
