In an article published in the journal Bioscience, 15,364 scientists warned that we are "jeopardizing our future" and that "immediate action" is needed to "safeguard our imperiled biosphere."
"Soon it will be too late to shift course away from our failing trajectory, and time is running out," the scientists say.
The article is meant to be an update on a 1992 notice — ominously titled "World Scientists' Warning to Humanity" and signed by 1,700 leading scientists — that predicted environmental catastrophes to come if humans remained on the current course.
But the 1992 statement was wildly off the mark in its dire predictions.
Back then, the world's leading scientists said that, if current trends continued, air pollution would get worse, water supplies would run short, the world's supply of fish would sharply decline because of dying oceans, land would become less productive, vast acres of forests would be "gone in a few years," mass extinctions would limit the ability to develop new medicines, and unchecked population growth would cause more to live in poverty and suffer malnutrition.
