Earth’s ecosystems support all life, though collapsed ecosystems would be like stepping outside of the international space station not wearing a space suit. Pop! Bam! Gone!
A recent academic study about signals of ecosystem collapse throughout history fits the space suit analogy. Terrifying truth is exposed: The all-important biosphere is sending out warning signals of impending crises… worldwide. It does not seem possible that ecosystems collapse and life dies off. That’s too hard to believe… but, what if it does collapse?
The Earth’s biodiversity is under attack. We would need to travel back over 65 million years to find rates of species loss as high as we are witnessing today.
Biodiversity increases resilience: more species means each individual species is better able to withstand impacts. Think of decreasing biodiversity as popping out rivets from an aircraft. A few missing rivets here or there will not cause too much harm. But continuing to remove them threatens a collapse in ecosystem functioning. Forests give way to desert. Coral reefs bleach and then die.
It’s already happening! Imagine flying in an aircraft while watching the rivets pop, one by one. At some point in time screaming overrides thinking. But, thank heavens; we’re not quite there yet.
Scientists from University College London and the University of Maryland studied 2,378 archeological sites and discovered that every society for thousands of years gave early clues to its own…
