The sixth mass extinction of global wildlife already under way is seriously threatening the world’s food supplies, according to experts.
There are tens of thousands of wild or rarely cultivated species that could provide a richly varied range of nutritious foods, resistant to disease and tolerant of the changing environment. But the destruction of wild areas, pollution and overhunting has started a mass extinction of species on Earth. The focus to date has been on wild animals – half of which have been lost in the last 40 years – but the new report reveals that the same pressures are endangering humanity’s food supply, with at least 1,000 cultivated species already endangered.
Researchers in England believe at least 150 studies on evolution and biodiversity penned since 2007 stand on shaky scientific ground — built on poor analysis and flawed assumptions.
The authors of a new study, published in the journal Methods in Ecology and Evolution, argue recent attempts to “correct” the fossil record have further perverted it.
Just when climate change demands a more diverse and adaptable food system, resilient to changing conditions, agriculture is being dragged further down an ever-narrowing agroindustrial route.
Habitat destruction has reduced the variety of plants and animals to the point that ecological systems could become unable to function properly, with risks for agriculture and human health, say scientists.
A new study suggests our knowledge of Earth’s biodiversity is extremely limited. According to the numbers recently crunched by scientists at Indiana University, 99.999 percent of the planet’s species remain undiscovered.
International efforts to meet targets to stem the loss of wildlife and habitats are failing miserably, according to a UN report.
The Global Biodiversity Outlook 4, published as nearly 200 countries meet on Monday in South Korea in a bid to tackle biodiversity loss, paints a damning picture of governments’ efforts to meet a set of targets agreed in 2010 to slow the destruction of species’ habitats, cut pollution and stop overfishing by the end of the decade.
