New study finds Almost half the world's species are seeing rapid population declines

We need to reduce our population and refocus it in the cities. The rest of the world needs to be off limits and for animals only. We either wake up to this reality or our planet turns to shit.
Humans have already wiped out huge numbers of species and pushed many more to the brink – with some scientists saying we are entering a “sixth mass extinction” event, this time driven by humans.
The main factor is the destruction of wild landscapes to make way for farms, towns, cities and roads, but climate change is also an important driver of species decline and is predicted to have an increasingly worse impact as the world warms.
The study’s authors analyzed more than 70,000 species across the globe – spanning mammals, birds, reptiles, amphibians, fish and insects – to determine whether their populations have been growing, shrinking or remaining steady over time.
They found 48% of these species are declining in population size, with fewer than 3% seeing increases, according to the study published Monday in the journal Biological Reviews.
For decades, the extinction crisis has been defined by “conservation categories” – labels that the International Union for Conservation of Nature, a United Nations committee, assigns to each species they assess at a given moment in time, Pincheira-Donoso said.
Based on that method, the IUCN’s Red List of Threatened Species classifies about 28% of species as under threat of extinction.
“What our study shows is not whether species are currently classed as threatened or not, but instead, whether their population sizes are becoming rapidly and progressively smaller or not,” Pincheira-Donoso said. Downward trends in population over time are a precursor to extinctions.
According to this assessment, 33% of the species currently classed as “non-threatened” on the IUCN Red List are in fact declining towards extinction.
