Amazon rainforest is approaching a tipping point of transitioning to a savannah
"Deforestation and climate change, via increasing dry-season length and drought frequency, may already have pushed the Amazon close to a critical threshold of rainforest dieback.... We find that more than three-quarters of the Amazon rainforest has been losing resilience since the early 2000s, consistent with the approach to a critical transition. Resilience is being lost faster in regions with less rainfall and in parts of the rainforest that are closer to human activity."
Conservation of Earth's biodiversity is embedded in Indigenous fire stewardship
"Indigenous peoples comprise 5% of the world population but protect approximately 85% of its biodiversity through stewardship of indigenous-managed lands. ... Supporting indigenous-led fire stewardship can assist with reviving important cultural practices while protecting human communities from increasingly severe wildfires, enhancing biodiversity, and increasing ecosystem heterogeneity."
Wildlife populations have plummeted by two-thirds in 50 years
Natural areas that used to support biodiversity and have been converted for farming are the biggest reason for the population decline of thousands of species around the world. The WWF study has found that the average population size has dropped by 68% worldwide between 1970 and 2016.
