By 2050, up to 47% of the world's largest tropical forest could reach a point of no return and transform into steppe. More than a third of what remains of the Amazon rainforest is degraded by human activities.
Scientists are recording an increase in the mortality rate of trees, a sign in particular of water stress which could “ trigger the collapse of the forest’s ecosystems. The consequences of such a scenario would be felt around the world. But researchers insist it is not yet too late to avoid the point ofno return.
