A three-year UN-backed study from the Intergovernmental Science-Policy Platform On Biodiversity and Ecosystem Services has grim implications for the future of humanity.

Nature is in freefall and the planet’s support systems are so stretched that we face widespread species extinctions and mass human migration unless urgent action is taken. That’s the warning hundreds of scientists are preparing to give, and it’s stark . . .

. . . The study from the Intergovernmental Science-Policy Platform On Biodiversity and Ecosystem Services (IPBES), expected to run to over 8,000 pages, is being compiled by more than 500 experts in 50 countries. It is the greatest attempt yet to assess the state of life on Earth and will show how tens of thousands of species are at high risk of extinction, how countries are using nature at a rate that far exceeds its ability to renew itself, and how nature’s ability to contribute food and fresh water to a growing human population is being compromised in every region on earth.

The world’s insects are hurtling down the path to extinction, threatening a “catastrophic collapse of nature’s ecosystems”, according to the first global scientific review.

More than 40% of insect species are declining and a third are endangered, the analysis found. The rate of extinction is eight times faster than that of mammals, birds and reptiles. The total mass of insects is falling by a precipitous 2.5% a year, according to the best data available, suggesting they could vanish within a century.

The population of the planet's vertebrates has dropped an average of 60 percent since 1970, according to a report by the WWF conservation organization.

The most striking decline in vertebrate population was in the tropics in South and Central America, with an 89 percent loss compared to 1970. Freshwater species have also significantly fallen — down 83 percent in that period.

The Living Planet Index, provided by the Zoological Society of London (ZSL) and included in the WWF Living Planet 2018 report, tracked the population of mammals, birds, fish, reptiles and amphibians around the world between 1970 and 2014, the latest year for which data was available.

Three-quarters of flying insects in nature reserves across Germany have vanished in 25 years, with serious implications for all life on Earth, scientists say

The abundance of flying insects has plunged by three-quarters over the past 25 years, according to a new study that has shocked scientists.

Insects are an integral part of life on Earth as both pollinators and prey for other wildlife and it was known that some species such as butterflies were declining. But the newly revealed scale of the losses to all insects has prompted warnings that the world is “on course for ecological Armageddon”, with profound impacts on human society.
