A new study led by researchers at the University of Oxford has used the fossil record to better understand what factors make animals more vulnerable to extinction from climate change. The results, published today in the journal Science, could help to identify species most at risk today from human-driven climate change.

Plastic waste in aquatic environments may be severely disrupting the reproductive behavior of marine animals. 

The ivory-billed woodpecker, along with 22 other species of birds, fish, mussels and other wildlife, is set to be declared extinct and removed from the endangered species list, US federal wildlife officials announced Wednesday.

There is hardly any other food that pollutes our environment and the climate as badly as meat. However, no government in the world currently has a concept of how meat consumption and production can be significantly reduced. But if the sector continues to grow as it has up to now, almost 360 million tons of meat will be produced and consumed worldwide in 2030. With ecological effects that are hard to imagine.

Wild relatives of some of the world’s most important crops, including potatoes, avocados and vanilla, are threatened with extinction, according to a study. Vanilla, an orchid native to South and Central America, is facing the highest risk of extinction, with all eight wild species found in the region listed as endangered or critically endangered on the International Union for the Conservation of Nature’s (IUCN) red list of threatened plants and animals.

Climate change is a critical factor affecting biodiversity. However, the quantitative relationship between temperature change and extinction is unclear. Here, we analyze magnitudes and rates of temperature change and extinction rates of marine fossils through the past 450 million years (Myr). The results show that both the rate and magnitude of temperature change are significantly positively correlated with the extinction rate of marine animals.

More than 1 billion marine animals along Canada’s Pacific coast are likely to have died from last week’s record heatwave, experts warn, highlighting the vulnerability of ecosystems unaccustomed to extreme temperatures.

The root cause of pandemics – the destruction of nature – is being ignored, scientists have warned. The focus of world leaders on responding to future outbreaks overlooks the far cheaper and more effective strategy of stopping the spillover of disease from animals to humans in the first place, they have said. The razing of forests and hunting of wildlife is increasingly bringing animals and the microbes they harbour into contact with people and livestock. About 70% of new infectious diseases have come from animals, including Covid-19, Sars, bird flu, Ebola and HIV.

According to a new study from the Aarhus University in Denmark, humans will continue to wipe out mammalian species for the next 50 years, so much so that Earth will need three to five million years to recover its evolutionary diversity.
