Thank you for publishing this article, which documents the alarming effects of climate change in one of the world's most biodiverse regions: The Amazon rainforest.
However, there is are two critical facts missing from the article which we should all be aware of.
It is widely believed that the Amazon forest produces some 20 per cent of the world's oxygen which much of life on this planet depends and is estimated to hold roughly one-fifth of world's fresh water supply.
If the Amazon forest is destroyed, we do risk a crisis of truly Biblical proportions which may be irreversible as massive releases of carbon dioxide into the atmosphere (from fires and drought-related death) will not be easily removed and may spiral into a vicious cycle causing runaway heating until the Earth achieves a new equilibrium point which may not sustain life on this planet any further. We also risk forever losing the as yet unknown biological secrets of this incredibly dense ecosystem that may hold biochemical clues to solving diseases such as cancer.
We should all be alarmed by the effects of climate change as we rapidly alter Earth's natural homeostasis that has required millennia and longer for nature to create.
