Humanity thinks of itself differently to all other life on Earth, but even we are not immune to the laws of nature. One expert has said that all life on Earth eventually goes extinct, and humans are no different.
Nick Longrich, a senior lecturer at the University of Bath, said humans are “inevitably” heading to extinction, and it is a matter of when, not if.
One just needs to look at all of humanity’s relatives – such as Neanderthals, Denisovans and Homo erectus – to determine that we will eventually follow the same path.
He wrote for The Conversation: “Will our species go extinct? The short answer is yes. The fossil record shows everything goes extinct, eventually. Almost all species that ever lived, over 99.9 percent, are extinct.
“Some left descendants. Most – plesiosaurs, trilobites, Brontosaurus – didn’t.
“That’s also true of other human species. Neanderthals, Denisovans, Homo erectus all vanished, leaving just Homo sapiens.
“Humans have vulnerabilities. Large, warm-blooded animals like us don’t handle ecological disruptions well.
“Small, cold-blooded turtles and snakes can last months without food, so they survived.
Humans have made habitats virtually everywhere across the planet in many different conditions – something which the rest of the animal kingdom has not accomplished.
Mr Longrich said: “Geographically widespread organisms fare better during catastrophes such as an asteroid impact, and between mass extinction events.
“Large geographic range means a species doesn’t put all its eggs in one basket. If one habitat is destroyed, it can survive in another.
“Polar bears and pandas, with small ranges, are endangered. Brown bears and red foxes, with huge ranges, aren’t.
“Humans have the largest geographic range of any mammal, inhabiting all continents, remote oceanic islands, in habitats as diverse as deserts, tundra, and rainforest.
“But this adaptability sometimes makes us our own worst enemies, too clever for our own good.
“Changing the world sometimes means changing it for the worse, creating new dangers: nuclear weapons, pollution, overpopulation, climate change, pandemics.
“So we’ve mitigated these risks with nuclear treaties, pollution controls, family planning, cheap solar power, vaccines. We’ve escaped every trap we set for ourselves.
