The soft sound of bees buzzing among flowers signals warm weather throughout the world. But in many places, those sounds are fading. And it’s not just honeybees that are struggling. Native bees, including bumblebees, are also becoming scarce. Factors such as climate change and habitat loss may be partly to blame. But a new study points to the threat posed by a common pesticide. Bumblebees exposed to this chemical had a harder time learning. And it was true even when bees ate pesticide-laced food only as larvae.

A “substantial” recovery of life in the oceans could be achieved by 2050 if major threats such as climate change are dealt with, a study has said. The oceans are important sources of food, water and clean energy and key for tackling global warming as they store heat and carbon, but many marine species, habitats and ecosystems have suffered catastrophic declines.

Many plant species are in danger of extinction. But scientists at the UK’s Royal Botanic Gardens at Kew are working with industry to find real-world solutions.

The interstellar object (alternatively a comet or an asteroid) that killed the dinosaurs when it slammed into Earth didn't work alone. Researchers have shown previously that its after-effects, such as tidal waves and earthquakes, played an important role in the mass extinctions of three-fourths of plant and animal life. Now, new research suggests that one of the most important factors was the soot-rich smoke from fires sparked by the collision.

They died of thirst on a remote Alaskan island. By Bryson Masse.

The thylacine, or Tasmanian tiger, believed extinct, had the quick wit of a killer new research reveals. By Gemma Tarlach.

At the end of the last Ice Age, most large animals in North America were wiped out, and others transformed themselves. Yet one has survived virtually unchanged to the present day. Where cars now drive along congested roads in the heart of modern Los Angeles, sabre-toothed cats once roamed. They stalked prey that ranged from hoofed mammals to creatures resembling elephants. The ferocious cats competed with dire wolves, American lions and short-faced bears.

World population keeps increasing. Humanity spreads all over the world just like a cancer, causes other species to go extinct, and changes the face of the earth. The net population in the world continues to increase at an alarming rate.

The world is hurtling towards the first mass extinction of animal life since the dinosaurs were wiped out 65 million years ago, according to the most comprehensive survey of wildlife ever carried out. By 2020, the populations of mammals, birds, fish, reptiles and other vertebrate species are on course to have fallen by more than two-thirds over a period of just 50 years, the Living Planet report found.

Stephen Hawking is one of many scientists who see the possible near-term demise of our species. Spend that 401k! By Phil Torres.

Penguin populations around the world are in decline and now New Zealand's Yellow-eyed penguins slip toward extinction. At their rate of decline, Yellow-eyed penguins will vanish from the Otago Peninsula of New Zealand in about 40 years.

Global Warming is the root cause because of which the 1st mammal species goes extinct. The Bramble Cay Melomys is the 1st mammal to go extinct.

'Extinction rates for birds, mammals and amphibians are similar to the five global mass-extinction events of the past 500 million years that probably resulted from meteorite impacts, massive volcanism and other cataclysmic forces'

When six massive endangered animals turn up dead in the span of a few weeks, conservationists do everything they can to find out why. Although they seemed otherwise healthy, the North American right whales were all recently found dead in the Gulf of St. Lawrence in Canada. Now, Fisheries and Oceans Canada, the Marine Animal Response Society, the Canadian Coast Guard, and others are working together to find out why the whales died.

When plant and animal species go extinct, it's usually a clear sign that humans have messed up. We've over-hunted, destroyed habitats, polluted waterways, and altered the climate by burning fossil fuels, wiping species off the planet for good. We tend to study extinctions to understand just how much we have disrupted the planet's ecosystems. But in a new scientific study published on Monday, scientists said we're not paying nearly enough attention to the "prelude" to global extinction...

Shark fins and manta ray gills found for sale in stores and markets in Vancouver and in China just a few years ago belonged mainly to species that are now listed as at-risk and banned for trade, DNA testing shows. Researchers led by Dirk Steinke at the University of Guelph found that 71 per cent of more than 100 samples tested belonged to species that are considered at risk of extinction, including the whale shark, the largest fish in the world. It has been listed as "vulnerable" by the International Union of Conservation since 2003.

Has the chilling threat of extinction worn off at last for the long-endangered snow leopard? Not exactly - but the iconic big cats' conservation status has been improved from "endangered" to "vulnerable". The decision was announced by the International Union for Conservation of Nature (IUCN) - the global standard for assessing extinction risk.

According to several scientists, Earth is on the brink of a mass extinction of species including flora and fauna, mainly because of the human activity. This is a serious case or is all about propaganda released by the new world order? Which is finally the truth? We are all familiar with the theory of the extinction of the dinosaurs took place 66 million years ago. According to this theory, an asteroid crashed into Earth and led to the extinction of a vast proportion of living beings. On the contrary, few know that another 5 times in the past, life on the planet came very close to extinction.

The abundance of flying insects has plunged by three-quarters over the past 25 years, according to a new study that has shocked scientists. Insects are an integral part of life on Earth as both pollinators and prey for other wildlife and it was known that some species such as butterflies were declining. But the newly revealed scale of the losses to all insects has prompted warnings that the world is “on course for ecological Armageddon”, with profound impacts on human society.

A bird group named the Vegaviidae, which resembled modern loons and geese, is the first identified with members that lived before and after the Cretaceous extinction
