More than 15,000 scientists from around the world have signed a terrifying letter warning of an imminent apocalypse.
The message is called “Warning to Humanity” and is an ominous vision of the grim fate awaiting our planet.
The message updates an original Warning from the Union of Concerned Scientists, which was made in 1992.
Now the global scientific community’s view of the future is even bleaker.
Apart from the hole in the ozone layer, which has now been stabilised, every one of the major threats identified in 1992 has worsened.
Runaway consumption of precious resources by an exploding population remains the biggest danger facing humankind, say the scientists.
They urge “scientists, media influencers and lay citizens” to put pressure on governments to reverse the trend.
A host of environmental calamities are highlighted in the warning notice, including catastrophic climate change, deforestation, mass species extinction, ocean “dead zones”, and lack of access to fresh water.
Writing in the online international journal BioScience, the scientists led by top US ecologist Professor William Ripple, from Oregon State University, said: “Humanity is now being given a second notice … We are jeopardising our future by not reining in our intense but geographically and demographically uneven material consumption and by not perceiving continued rapid population growth as a primary driver behind many ecological and even societal threats.
“By failing to adequately limit population growth, reassess the role of an economy rooted in growth, reduce greenhouse gases, incentivise renewable energy, protect habitat, restore ecosystems, curb pollution, halt defaunation, and constrain invasive alien species, humanity is not taking the urgent steps needed to safeguard our imperilled biosphere.”
In their original warning, scientists including most of the world’s Nobel Laureates argued that human impacts on the natural world were likely to lead to “vast human misery”.
The new notice, written as an open-letter “viewpoint” article, won the support of 15,364 scientists from 184 countries who agreed to offer their names as signatories.
