Many animal species are on the brink of extinction.

Many shark species are threatened with extinction.

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

Just like every species has an important gift to give to the ecosystem, and the extinction of any species hurts everybody.

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

For the 10,000 bird species, there should only be one extinction in each century.

Every year, more species many of them not even named become threatened with extinction or go extinct.

As for biodiversity, the most important species threatened with extinction today is the human race.

The Age of Extinction

Of the world's species, 12 of birds, 24 of mammals, and 30 of fish are either vulnerable or in immediate danger of extinction.

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).

Senator Manny Villar is worried that the frenzied gecko hunting could lead to the extinction of the species in the country

So what it tells us actually is that there's actually a risk of extinction of this species because its population is so small.

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

What are catastrophic effects? A three degree centigrade climate change rise that will result in 50 percent species extinction.

Flora includes 909 species, including 645 species of vascular plants, 151 species of fungi, 48 species of lichens, 65 species of moss.

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.

They are in danger of extinction.

Extinction is a part of evolution.

Blue fin tuna is heading for commercial, if not outright, extinction, as are a host of other economically and ecologically important marine species.

There are 62 species of mammals, more than 270 species of birds, 39 species of fishes, 6 species of reptile and 9 species of amphibians.

The Extinction Puzzle

The Last Extinction

It is feared that these new hydroelectric dams could lead to the extinction of many of the fish species that are endemic to the river.

To avoid such uncertainties, my colleagues and I introduced the extinction rate the number of extinctions per year per species or, to make the numbers more reasonable, extinctions per million species years E MSY.

Global demand for fish consumption is growing, and so, too, is the global capacity to catch fish, driving some species to the point of extinction.

In the case of sharks and rays, a recent survey indicates that close to one third of the 64 ocean living species are on the verge of extinction.

For example, they hoped that certain species of fish like the New Zealand snapper would return because they had been fished to the brink of commercial extinction.

Ongoing loss is driving fears of mass extinction.

These animals are on the verge of extinction.

Many kinds of animals are threatened with extinction.

Tropical forests, for example, hold the majority of bird species and likely most other kinds of species too. If present trends of deforestation continue, we project bird extinction rates to climb to 1,500 E MSY by the last decades of this century.

Some, such as E. O. Wilson of Harvard University, predict that human destruction of the biosphere could cause the extinction of one half of all species in the next 100 years.

And livestock production uses 30 of the earth s land surface that once was home to wildlife, thereby playing a critical role in biodiversity loss and species extinction.

In 1992, when the world s governments first promised to address man made global warming, they also vowed to head off the human induced extinction of other species.

Some wild animals are on the verge of extinction.

Some wild animals are on the brink of extinction.

For example, we may regret that we can no longer see some species of wild animal that has been hunted to extinction by people who lived centuries ago.

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.

The Wealth of Species

A seminal 1998 study led by David Wilcove, now an ecologist at Princeton, cites invasive species as the second leading cause of extinction in the U.S., after habitat loss.

Early European exploration likely continued this rapid pace of extinction.

There's six million species of insects on this planet, six million species.

Kerala's fauna are notable for their diversity and high rates of endemism it includes 102 species of mammals (56 of which are endemic), 476 species of birds, 202 species of freshwater fishes, 169 species of reptiles (139 of them endemic), and 89 species of amphibians (86 endemic).

Amber Mountain National Park is home to a huge number of endemic species. So far, there have been reported sightings of 77 different species of birds, seven species of lemurs, and 24 species of amphibians.
