Between a quarter and a third of the world's wildlife has been lost since 1970, according to data compiled by the Zoological Society of London.
Populations of land-based species fell by 25%, marine by 28% and freshwater by 29%, it says.
Humans are wiping out about 1% of all other species every year, and one of the "great extinction episodes" in the Earth's history is under way, it says.
Pollution, farming and urban expansion, over-fishing and hunting are blamed.

I have returned and watched patiently for a reply, and then waited for a week and a half more for a decent response to the manifold questions which you seem disinclined to answer.
I refuse to continue to dignify this thread with an ongoing tab in my Firefox window when I have so many more pressing uses for my online time. If you ever feel inclined to engage again you are welcome to find me at Deltoid. Tim Lambert has an ongoing Open Thread that is appropriate for this purpose.
I am sure that you know how to find it...

I won't bother to link. You can easily google, although I'm sure that you know the way...
