I would assume that the seaweed collects CO2 to grow. Can we harvest and burn it for fuel? Or feed it to something that is willing to eat it, like cattle? Or sink it to the bottom of the ocean in a way that will keep the CO2 sequestered?
I remember seeing something about how a last resort action against climate change would be to seed massive amounts of fertilizer across the ocean to cause a super alage bloom (and fuck everything else living in the ocean). I wonder if this fertilizer abuse may end up saving us from (one) global disaster after all.
Every sane country in the world should be threatening or applying sanctions on Brazil for our insane decisions concerning the Amazon and the potential impact on the whole planet. If the authors are right and this is due to unrestrained exploration in the Amazonas basin, this is not going to change until Bolsonaro is either forced to stop or leaves office.
