Two major reports released this month paint a grim portrait of the future for our planet’s wildlife. First, the You do not have permission to view the full content of this post.

The study analyzed population sizes of 4,392 monitored species of mammals, fish, birds, reptiles, and amphibians from 1970 to 2016, reports Karin Brulliard for the You do not have permission to view the full content of this post.

All told, the drastic species decline tracked in this study “signal a fundamentally broken relationship between humans and the natural world,” the WWF notes in a You do not have permission to view the full content of this post.

The WWF report singles out habitat destruction caused by humans as the main threat to the world’s biodiversity. For example, freshwater mammal, bird, amphibian and reptile populations have declined by an average of four percent each year since 1970.

Yet according to the U.N.’s report, the world has collectively failed to reach a single one of those goals in the last decade, reports Catrin Einhorn for the You do not have permission to view the full content of this post.

The U.N. report did contain bright spots. For instance, experts pointed to the efficacy of human-led conservation efforts, such as a program in Pakistan that protects snow leopards and a campaign to save the Japanese crested ibis from extinction, reports Matthew Green for You do not have permission to view the full content of this post.

“Earth’s living systems as a whole are being compromised,” adds Mrema. “And the more humanity exploits nature in unsustainable ways and undermines its contributions to people, the more we undermine our own wellbeing, security and prosperity.”

However, as Rott notes, the report indicates that the ever-growing population of humans has led to an “ecological imbalance,” where society requires more resources to survive than can be produced. According to their models, the researchers conclude: “The human enterprise currently demands 1.56 times more than the amount that Earth can regenerate.”
