Amazon rainforest nears tipping point that may see it become savannah

More than three-quarters of the world's largest rainforest has become less resilient to drought since the early 2000s, with areas near humans and with lower rainfall being the worst hit

The Amazon rainforest is nearing a tipping point that will see it transform into savannah, according to researchers who have found that the biodiversity hotspot has lost resilience in the past two decades.
Previous studies have warned that the world’s largest rainforest, which acts as a vital brake on climate change, is approaching a critical threshold. But most past research has relied on projections using models, not real world observations.
The Amazon contains between 90 and 140 billion metric tons of carbon
It’s everywhere: in the rain, snow, our food, our waters, even in the human placenta! Mercury is poisoning life on Earth.
ARE YOU AWARE Artisanal miners' gold ore processing produces 20% of the world's supply of gold used in our jewellery, iPad’s, iPhone, computers, and other electronics devices and is the world's largest anthropogenic source of deadly mercury pollution overtaking coal fired plants mercury emissions in 2017?
Artisanal miners' ore processing uses mercury, a deadly neurotoxin and precursor to an even deadlier neurotoxin Methylmercury @ 100 times more potent than elemental mercury to extract liberated gold from crushed or milled ore by forming an amalgam which is vaporized leaving the gold while releasing 2,000 tonnes of mercury to our atmosphere annually .
Mercury pollution is documented in 2021 by Oxford University earth scientists to stay airborne up to one year then precipitates back to Earth in the form of rain and snow.
The morbid irony lies in the fact the same vaporized mercury is polluting the air we all breathe, contaminating our drinking water, polluting the Oceans we swim, poisoning the fish we consume especially tuna where mercury bioaccumulates the most causing health issues, and global biodiversity destruction.
But finally there's hope!
