Humans have destroyed a tenth of Earth’s remaining wilderness in the last 25 years and there may be none left within a century if trends continue, according to an authoritative new study.
Researchers found a vast area the size of two Alaskas – 3.3m square kilometres – had been tarnished by human activities between 1993 and today, which experts said was a “shockingly bad” and “profoundly large number”.
The largest chunk of wilderness in the Amazon basin shrank from 1.8m sq km to 1.3m sq km, while the Ucayali moist forests in the west of the Amazon, home to more than 600 bird species and primates including emperor tamarins, was badly affected.
The Amazon accounted for nearly a third of the “catastrophic” loss, showing huge tracts of pristine rainforest are still being disrupted despite the Brazilian government slowing deforestation rates in recent years.
