and experts worry the amazon ecosystem itself is changing. i'm very concerned. previous research have been understanding that the amazon was much more resilient and that our tipping point, leading to the decivilization the large trenches of the forest would happen if about 40% of the amazon was lost and now recent research is pointing towards figures closer to 20% — and we already are at those figures. it appears to be becoming less rainy and the fear is the forest could begin to give way to grassland.
