The Age of Extinction

The Extinction Puzzle

This bird is in danger of dying out.

They are in danger of extinction.

These animals are on the verge of extinction.

How many languages are in danger of dying?

Some wild animals are on the brink of extinction.

Many shark species are threatened with extinction.

Many animal species are on the brink of extinction.

As rocks and mountains die, grains of sand are born.

But does the earth have to wait for our extinction as a species?

The beautiful bird is said to be in danger of dying out.

That species of bird is said to be in danger of dying out.

Present day extinction rates are 100 1000 times greater than the background rate and up to 30 of current species may be extinct by the mid 21st century.

For this reason, some colleagues and I have calculated the rate at which bird species became extinct in the recent past and the rate at which they will likely become extinct in the future.

With the exception of the past five mass extinction events, estimates from the fossil record suggest that an approximate background rate is one extinction per million species years, (1 E MSY).

The extinction rate is 1,000 times higher than normal, and is increasing.

Early European exploration likely continued this rapid pace of extinction.

The title of my talk Shape shifting Dinosaurs The Cause of a Premature Extinction.

We nearly went extinct. We were hanging on by our fingernails.

Freshwater Finless Porpoises which inhabit the Yangtze River are now on the verge of extinction.

And there'd also be an extinction event like fossils would suddenly disappear.

The danger is not at all unprecedented. Species go extinct all the time.

Recently it was pronounced extinct the first documented extinction of a primate since the 1700s.

Nevertheless, future rates of extinction constitute a problem that will be very much harder to solve.

Should report on the Birth Planning Department, it attempted to make the Han race go extinct .

And there's two things that are really evident here to me, is that these extinctions take place when CO2 is going up.

Extinct or endangered species are indicators of a much bigger problem.

Not only are 12 of bird species already in danger of extinction, but more than twice that proportion have small geographical ranges (the key predictor of threat) and mostly live in habitats that are seriously threatened.

And there is one clear measure of how we perform at that task extinction rates.

The herders and the chauris, the yak cow hybrids, disturb and destroy the red panda habitats, though not intentionally. Habitat loss is another major concern for conservationists.

Whale sharks are in danger of going extinct because of hunting, pollution, and habitat destruction.

Karbi is an endangered language spoken by about 41,900 people in the Indian state of Assam in northeastern India.

We added species that are probably extinct, too. With these two adjustments, the extinction rate has been about a 100 times higher than natural over the last two centuries.

With these two adjustments, the extinction rate has been about a 100 times higher than natural over the last two centuries.

Plant and animal species worldwide are vanishing at an unprecedented pace 100 to 1,000 times the natural extinction rate.

And animals, almost on the brink of extinction, can be given a second chance. That's my next book.

We also need a regular scientific process to present the world with the evidence on species abundance and extinction, just as we now have such a process for climate change. Politicians don t listen very well to individual scientists, but they are forced to listen when hundreds of scientists speak with a united voice.

From the promotion of organic food to declarations of the polar bear s imminent demise, the media pelt us with a constant barrage of one sided warnings. The list of urgent concerns is topped by global warming, but also includes terrorism, pesticides, and the loss of biodiversity and seems to have virtually no end.

From the promotion of organic food to declarations of the polar bear s imminent demise, the media pelt us with a constant barrage of one sided warnings.

To get an accurate picture of extinction, we must adjust the total number of extinctions for the length of time science has known bird species.

Our predictions of twenty first century extinctions jump an order of magnitude to 1,000 E MSY.

Although geckos are not classified as either critically endangered, endangered or vulnerable, it is now under threat from over collection which can ultimately lead to vulnerability or extinction

Prioritizing the prevention and cleanup of pollution will not only save lives, but also mitigate climate change and reduce threats to biodiversity.

As a result, more than 10,000 species are threatened with extinction two thirds of all endangered species on the planet.
