WASHINGTON (AP) — Species of plants and animals are becoming extinct at least 1,000 times faster than they did before humans arrived on the scene, and the world is on the brink of a sixth great extinction, a new study says.

The study looks at past and present rates of extinction and finds a lower rate in the past than scientists had thought. Species are now disappearing from Earth about 10 times faster than biologists had believed, said the study's lead author, biologist Stuart Pimm of Duke University.

"We are on the verge of the sixth extinction," Pimm said from research at the Dry Tortugas. "Whether we avoid it or not will depend on our actions."

The work, published Thursday by the journal Science, was hailed as a landmark study by outside experts.

Pimm's study focused on the rate, not the number, of species disappearing from Earth. It calculated a "death rate" of how many species become extinct each year out of 1 million species.

In 1995, Pimm found that the pre-human rate of extinctions on Earth was about 1. But taking into account new research, Pimm and his colleagues refined that background rate to about 0.1.

Now, that death rate is about 100 to 1,000, Pimm said.

If the plant that is called Broccoli becomes extinct, I shalt not cry.

 lol!  I know, but I don't understand how anyone can work out how fast plants and animals became extinct before Humans came onto the scene  study 

I am worried about our bluebells though  flower

Well, I think I will see it, since my plan is to live forever and it's going really well so far.

Sad, isn't it, how we humans are dominating the planet so much that forests are fast disappearing, which is accelerating climate change, and many animals and birds are fast becoming extinct. Future generations will look at animals in zoos and marvel at how they used to roam wild. It will be beyond their belief.

In Britain, hundreds of miles of hedgerows have been cut down, and many species of birds and animals have become extinct, or dangerously near extinction.
