Re: Climate change could mean the extinction of our species
GMOs apparently have a negative effect on the bees, and once man starts genetically engineering the planet many imbalances are created as a result which throws the entire biosphere out of wack and there are many forms of alternative energy that have been surprised by GE and the mega oil corporations for years because of profit and there are underground bio weapon research facilities located throughout the world and yes Trish I agree many mineral mining and lumber practices are poorly regulated

yes Trish, the lengths the foundations and corporations will go to for the sake of year after year profit increases is scary

Re: Climate change could mean the extinction of our species
I am more concerned with mining and lumbering than with bees; the UK over the last century has lost a variety of insects like bees, and birds because the hedges that used to border fields have gone. Gm crops have been used to make new breeds of tobacco but I don't suppose this will stop people smoking. Incidentally, there was an item on the radio about 'City honey' made from bees who hive on rooftops in London. The argument is that the bees don't have access to countryside or gardens, but do have access to London's parks and that this gives their honey a more robust flavour than the more floral honey one associates with rural bees...

Re: Climate change could mean the extinction of our species
Bee colony collapse seems most likely due to a virus where the vector is the varroa mite. The role of some pesticides has also been suggested - ironically GM crops mean less pesticides. It is not a lost of habitat to blame.
Decline in bird populations are probably due to a variety of reasons - including habitat loss, climate changes, monocultures, etc. Since World War II, hedgerows have been removed at a much faster rate than they have been planted. In some parts of the UK 50% of hedgerows have gone, while others are so badly managed that their value to wildlife is much reduced. This process essentially ceased in the mid-90s. The most likely cause for some species, especially those that migrate, is climate change. If you as a bird fly from Africa to Northern Europe to breed in the Summer, you now fly a few 100 miles more to find the right climate. As with all breeding, if the timing is wrong and you are knackered, yo don't breed too well.

Albert Einstein on Bees: "If the bee disappears from the surface of the earth, man would have no more than four years to live. No more bees, no more pollination … no more men!"
And, too, Bats pollinate plants. Hopefully they don't go extinct. (But 99.9999 percent of all life that has ever existed is extinct. The dinosaurs had a good run. Sharks, too. They've been around for oh... roughly 400 million years. We've been around for 2 million in one stage or another. Or 6,000 years depending on how irrational one is --)
Loss of biodiversity is very worrying, too.
As Stavros pointed out: deforestation and mining should worry us.
The acidification of the oceans should worry us.
Mass consumerism should worry us. Mass production, too.
Noam Chomsky was asked: Will we be around in 500 years? He laughed.
This is our culture.... Well, not really. It's difficult to talk to Americans about culture. Because culture isn't Wal-Mart, it isn't McDonald's. It isn't Brad Pitt or Angelina Jolie. It's a set of values. We have no values. (Take, say, indigenous people. They're closely connected with and to nature. We aren't. It explicates a lot. Not valuing nature means we're in a whole heap of trouble.)

Re: Climate change could mean the extinction of our species
I agree with most of this, mostly with regard to birds -but in the case of bees, where does a virus come from? Could it be that some pesticide somewhere or something chemical being used in gardens infects bees? When different species of bee were cross-bred and the result was the 'African Killer Bee' did this also create a virus that most bees are not immune to? I don't know, but this would not be climate change as the factor, but science and nature.

Re: Climate change could mean the extinction of our species
The current hypothesis is that bee colony collapse is due to a viral infection carried by mites...
http://www.guardian.co.uk/environmen...structor-mites
Crossbreeding bees doesn't create viruses. One has to be careful though that the bees you bring in to crossbreed with your home variety aren't already infected. I suppose it's possible that the hybrid bee that you create might be more susceptible to the deliterious effects of infection. But that doesn't seem to be the case here, since all honey bees are at risk, not just certain crossbreeds.
Also chemical pollutants are not likely to produce new viruses though they through selection change the distribution of genes in the gene pool of a particular virus; i.e. they make create an environment where the more virulent strains have a greater reproductive advantage than they previously had. Certain pollutants may also simply render honey bees more susceptible to a virus that's been around for decades. Or chemical pollutants might make colony collapse a more likely response to infection by a virus that's been around awhile. Nothing I've read indicates which if any of these scenarios applies to the current problem. Viruses evolve to exploit natural shifts as well as artificial shifts in their environment.
Pollination is big business in the U.S. and bees are transported over long distances to pollinate fields and orchards. The stress of transportation and the higher chance of being exposed to viruses increases the chance of spreading diseases among honey bees.

Doesn'[t seem to be affecting the Africanized bees.
