Six of nine planetary boundaries—climate change, deforestation, biodiversity loss, synthetic chemicals including plastics, freshwater depletion, and nitrogen use—are already deep in the red zone, an international team of 29 scientists reported.
In a recent study, more than 40 international scientists assessed the planet’s capacity to provide a safe future. What they concluded is that Earth would fail in 7 of the 8 boundaries for a safe planet.
An international study led by the University of Queensland has found that human behavior is dramatically affecting a region of 2.3 million square miles - around twice the size of Alaska.
