"Humanity is “on the precipice” of shattering Earth’s limits, and will suffer
huge costs if we fail to act on biodiversity loss, experts warn. This week,
world leaders meet in Cali, Colombia, for the Cop16 UN biodiversity conference
to discuss action on the global crisis. As they prepare for negotiations,
scientists and experts around the world have warned that the stakes are high,
and there is “no time to waste”.
“We are already locked in for significant damage, and we’re heading in a
direction that will see more,” says Tom Oliver, professor of applied ecology at
the University of Reading. “I really worry that negative changes could be very
rapid.”
Since 1970, some studies estimate wildlife populations have declined on average
by 73%, with huge numbers lost in the decades and centuries before. Passenger
pigeons, the Carolina parakeets and Floreana giant tortoises are among the many
species humans have obliterated. “It’s shameful that our single species is
driving the extinction of thousands of others,” says Oliver.
The biodiversity crisis is not just about other species – humans also rely on
the natural world for food, clean water and air to breathe. Oliver says: “I
think we will, certainly, in the next 15 to 20 years, see continued food
crises, and the real risk of multiple breadbasket failures … that’s in addition
to a lot of the other risks that might impact us through fresh-water pollution,
ocean acidification, wildfire and algal blooms, and so on.”"
