We’re in the middle of what environmentalists call a “biodiversity crisis,” with some scientists going so far as to suggest we’re heading toward another mass extinction event. Whatever you want to call it, climate change and human-caused habitat loss are causing a measurable reduction to wildlife populations around the globe.

Naturally, Peter Thiel is an investor in the company that came up with the idea.

​​From above, the closed Tulsequah Chief mine in northwest B.C. seems small as it sits by the Tulsequah River a few kilometers from the waterway’s confluence with the Taku River. But up close, the site is an “open, oozing wound,” said Guy Archibald, executive director of the Southeast Alaska Indigenous Transboundary Commission. “There’s bright orange water running down the hill, running into this huge pond of bright orange water that just overflows into the river.”

Louisiana officials announced they discovered the hatchlings of the world’s smallest sea turtle species on an island just off the coast of New Orleans for the first time in 75 years.

Kemp's ridley sea turtles have hatched in Louisiana's wilds, officials say, in a victory for barrier island restoration. The tiny turtle is also believed to be the world's most endangered.

Sir David Attenborough is set to host a new nature series for the BBC tentatively titled “Wild Isles.” The five-part series will introduce viewers to fauna and flora across Britain and Ireland, focusing on four main areas: woodlands, grasslands, freshwater and marine.  

Bee populations are declining. More than half of the bat species in the United States are in severe decline or listed as endangered. And international scientists recently announced the monarch butterfly is perilously close to extinction.

The recent addition of the monarch butterfly to the International Union for Conservation of Nature’s Red List of Threatened Species captured the attention of the media and public across North America. Rightly so. This brightly coloured butterfly is easy to recognize and one of the few endangered species you might find right in your backyard. But the monarch is just the latest to be added to a growing group of wild species found in Canada that are at risk of disappearing forever.

Wild tigers in Nepal have clawed their way back from the brink of extinction. There are now almost three times as many wild tigers in the country as there were in 2009, according to the Nepalese government.

The unexpected discovery of a 16th-century horse tooth in modern-day Haiti has provided credence for an age-old folk story about the origin of feral horses on an island off Maryland and Virginia.

A colony of bats was later discovered in the man's Illinois home, and he refused treatment despite the warnings.

Australia’s wildlife is increasingly threatened with extinction. One key driver of this is habitat clearing and fragmentation. An associated factor is the expansion of our road network, particularly the upgrade and duplication of our highways.

Latest figures show native birds have increased by 51 percent on Wellington's Miramar Peninsula. This includes a whopping 550 percent rise in the pīwakawaka / fantail population of, a 275 percent increase in riroriro / grey warblers, and a 49 percent increase in tūī.

They’ve been absent in the UK wild for thousands of years, but now a special project has welcomed these “woolly bulldozers” home.

The number of tigers in the wild has gone up dramatically since 2015 — largely because of improvements in monitoring them, but the species remains endangered.

In San Francisco’s salty South Bay, an ambitious wetlands restoration project is seeking to balance a return to the ecological past with the realities of a changing future.

There are 40% more tigers in the wild than previously thought, with as many as 5,578 around, though they remain an endangered species, according to a leading conservationist group. The jump in numbers was due to improved monitoring, with the population thought to be stable or increasing, said the International Union for Conservation of Nature (IUCN). Habitat protection projects showed that “recovery is possible”.

With close to a million species now threatened with extinction, it's not often you hear about a conservation success story. But as we first reported in November, the mountain gorillas of the East African nation of Rwanda are just that.

Some bats buzz like wasps and bees when grasped, and the sound seems to deter predatory owls. The findings reveal what may be the first known case of a mammal mimicking an insect, researchers report May 9 in Current Biology.
