* Monitored populations of vertebrates (mammals, birds, amphibians, reptiles and fish) have seen a devastating 69% drop on average since 1970
* Freshwater species populations have suffered an 83% fall
* The report's Living Planet Index shows that there is no time to lose in securing a nature-positive society
* Deforestation, human exploitation, pollution, and climate change were the biggest drivers of the loss
Many scientists believe we are living through the sixth mass extinction – the largest loss of life on Earth since the time of the dinosaurs – and that it is being driven by humans.
Tanya Steele, chief executive at WWF-UK, said: "This report tells us that the worst declines are in the Latin America region, home to the world’s largest rainforest, the Amazon. Deforestation rates there are accelerating, stripping this unique ecosystem not just of trees but of the wildlife that depends on them and of the Amazon’s ability to act as one of our greatest allies in the fight against climate change."
"Despite the science, the catastrophic projections, the impassioned speeches and promises, the burning forests, submerged countries, record temperatures and displaced millions, world leaders continue to sit back and watch our world burn in front of our eyes," said Steele. "The climate and nature crises, their fates entwined, are not some faraway threat our grandchildren will solve with still-to-be-discovered technology."
She added: "We need our new prime minister to show the UK is serious about helping people, nature and the economy to thrive, by ensuring every promise for our world is kept. Falling short will be neither forgotten nor forgiven."
