The story reads...:

Mass species extinction ''is under way''

PARIS: Earth''s animal and plant species are vanishing at unprecedented rates, evidence that the planet is facing a tsunami of mass extinction, experts gathering for a global conservation conference have warned.
Whether through habitat loss, pollution, hunting, or indirectly by global warming, humans are squarely to blame for what may be the first major die-off in 65 million years, they say.

From Sunday, more than 8000 ministers, UN officials, NGOs, scientists and business chiefs will brainstorm for 10 days in the Spanish city of Barcelona on how to brake this loss and steer the world onto a path of sustainable development.

The World Conservation Congress, held every four years, will also release an update on Monday of the famous Red List on biodiversity, deemed the global standard for conservation monitoring.

“The evidence is overwhelming - and we have really good data now - that what we are seeing is probably a mass extinction,” the sixth in 450 million years, said Michael Hoffman, a mammal expert at IUCN who worked extensively on the Red List.

The current pace of dieoff is 100 to 1000 times higher than the so-called “background rate” of extinction - the average rate, over millions of years, at which species bite the dust.

“Species extinctions across all these groups will have very far-reaching consequences on human beings,” he said.

The Red List will include the most comprehensive study ever made on the survival status of Earth''s more than 5000 mammals species.

The new biodiversity “bible” is the fruit of 1700 experts, and scientists who took part in the effort say it will make for grim reading.

The 2007 edition already shows more than a third of 41,000 species surveyed are facing extinction: a quarter of all mammals, one out of eight birds, one out of three amphibians, and 70 percent of plants.

Our closest evolutionary cousins, primates, are especially vulnerable.

Hunted for food and traditional medicines, their habitat dwindling, more than 70 percent of known species in Asia, for example, are under threat.

Science has identified more than 1.9 million species to date. If microbial organisms are included, this is probably only a tenth of the life forms on Earth.

“Biodiversity is disappearing at an accelerated rhythm and we have to act quickly to slow and prevent the extinction crisis,” said Julia Marton-Lefevre, director-general of the International Union for Conservation of Nature, organiser of the October 5-14 congress.

more junk science.
We don''t even begin to understand just how many of them there are so how can we know how many have been going extinct.

I''m trying really hard to feel comforted by your comment, strmrdr.
This list of extinctions is just of species that we KNOW of, is it not?
The story does state that

"Science has identified more than 1.9 million species to date. If microbial organisms are included, this is probably only a tenth of the life forms on Earth."

and that

"The 2007 edition already shows more than a third of 41,000 species surveyed are facing extinction: a quarter of all mammals, one out of eight birds, one out of three amphibians, and 70 percent of plants."

Either way, I feel my rejection of the subject is basically me wanting to ''hide under the pillow''. After all, what can I do?

Bye bye world *sniffs*

Storm, we may not know exactly how many beetle species there are, but we have a pretty good handle how many species are out there. We have been documenting species before Darwin was a household name. And now humans are in every part of the earth. When you hear about a new fish or monkey you hear about it because it IS news. Animal and plant species are the true jewels of our planet. It hurts my heart to think that the animals my kids look at in books, not just species you haven''t heard of but snow leopards, chimpanzees, gorillas, elephants, and yes polar bears may only exist in storybooks by the time my grandchildren are around.

If you accept Darwin then you have to accept that species go extinct and have been since the beginning of time. Survival of the fittest ya know.

fyi polar bear populations are increasing not going down.

The environmental lobby has been hijacked by nuts with money that finance junk science.
They have 0 credibility with anyone who actually takes the time to study the issues.

Case in point Mars is experiencing global warming.
I spose man caused that to eh?

Storm, yes, species go extinct all the time. However the rate of extinctions has gone way up. Many scientists believe we are in the midst of a 6th major extinction, any way you count it (even the most conservative scientists in this area). The extinctions are not soly due to changes in climate change, also human related habitat and ecosystem loss and deterioration, poaching, and air and water pollution. People think that the earth''s resources are bountiful and limitless and that''s how we''ve been treating them. It is clear we are using up resources such as water and land faster than they can recover. We are messing with incredibly complex interrelationships, things we don''t fully understand, and once a habitat is lost, it is lost forever.

I am with you Lara, it is very disturbing. You are like me 10 years ago. I used to collect clippings of the news regarding this but I stopped because it is so overwhelming.

It is interesting that you have raised the example of global warming. Australia is having a ''moral moment'' over global warming, our newly elected Labor Prime Minister is campaigning hard internationally for a tax on industries that produce carbon.

So the papers are full of pro- and anti- global warming science pieces. Generally though, the populist press and the general public overwhelmingly speak of global warming as a man made phenomenon. The government is running ads about the political/tax changes that are coming as a result of the global warming policies.

I am skeptical of global warming being a totally man made phenomenon. I also think that a lot of climate change problems are caused by countries right outside Australia''s jurisdiction - clearing rainforests in Brazil, for example, has a huge impact environmentally, yet what are our taxes going to do about that?

I think this extinction register is a different example of science. Partly because the losses are actually recorded, in a kind of ledger, and the information is less theoretical, and more specific.

I guess extrapolating that list of lost species into a kind of graph of future losses is a bit speculative. But... that''s what specialists in any field do, is it not? That''s how planning happens, in any area of industry or government. It is the integrity of the data - and the length of time that data has been collected - that gives a real pattern for future estimates...?
