Human activity and appetites have weakened Earth's resilience, pushing it far beyond the "safe operating space" that keeps the world liveable for most species, including our own, a landmark study said Wednesday.
For biodiversity, for example, if the rate at which species disappear is less than 10 times the average extinction rate over the last 10 million years, that is deemed acceptable.
In reality, however, extinctions are occurring at least 100 times faster than this so-called background rate, and 10 times faster than the planetary boundary limit.
Will the miracle of life actually survive our self-induced extinction?
