Luckily, the Earth’s sixth mass extinction has one thing going for it that the others didn’t-humans. Even radical land restoration efforts may therefore fail to end population declines by 2030.” “Model projections indicate that both increases and declines are expected for future bird and mammal abundance, with populations up to 2050 still responding to environmental changes that have already happened. “Using data for birds and mammals from around the world, we show that population trends are best explained by past changes in temperature and anthropogenic land use,” the study concludes.
Report: Global Catastrophic Event Coming. “This work shows that time is even shorter than had been thought.” “There is wide recognition that time is short for the integrated, ambitious actions needed to stop biodiversity loss by 2050,” writes Natural History Museum zoologist Richard Cornford along with other scientists. A study published in Proceedings of the Royal Society B: Biological Sciences last week concludes that not only is the sixth extinction real, it may be further along that we expected. And the actions of that species-both past and present-have big, long-lasting consequences. While extinctions on Earth might be old hat, this is the first threat to biodiversity caused by a single species living on the planet itself. Most scientists agree that we are now living through a sixth mass extinction, but this one isn’t caused by world-ending space rocks or lava-belching volcanoes-it’s caused by us. Everyone knows the cataclysmic, asteroid-sized drama that consigned the dinosaurs to oblivion, and 200 million years before that fiery inferno, all life on Earth was nearly ended thanks to unending volcanic eruptions. Stretched across its 4.6-billion-year history, the planet’s undergone five of them. The Earth is no stranger to mass extinctions. Despite this time lag, a concentrated, global conservation effort to reverse this trend is more pressing than ever. 
A new study says that there may be a time lag between when humans implement environmental actions and when these actions affect animals, meaning that effects of this mass extinction could be “locked in” up until 2050.Scientists agree that the Earth is currently undergoing the sixth mass extinction in its 4.6-billion-year history.
