    Please don't play to the southbeach1500 card, Paul. metta8 uses many news sources.

    If this is the beginning of the 6th Mass Extinction at least I'm at the right moment in history. I was gonna die soon anyway. To Hell with everyone who comes (or might have come) after me. Farewell climate change deniers, at least I'll never have to see the consequences.

    That was a reference to woodsmen's threads, cluttering the forums with NYT articles.

    But what about reincarnation, where you come back as a billionaire? icon_razz.gif

    ...They estimate that it would grow to rival the last great catastrophe of the past, when the dinosaurs and much else died out 65m years ago, in as little as three human lifetimes...

    ...the extinctions are being driven by the effects of just one single species, Homo sapiens. Such a mass extinction has not occurred before (with the possible exception, 2.5bn years ago, when a type of microbe evolved photosynthesis to spew out oxygen, a gas that would have been highly toxic to the other microbes living then, and these would have been pushed to the fringes of life on Earth – where they still remain)...

    ...In all, our single species now commandeers somewhere between 25% and 40% of primary productivity on Earth...

    ...measured by mass, humans now make up a third of land vertebrates, and the animals that we keep to eat – cows, pigs, sheep and so on – make up most of the other two thirds. All the wild animals – elephants, giraffes, tigers and so on – are now less than 5% by mass. It’s a measure of how they have been pushed to the fringes by humans...

    Averting a dramatic decay of biodiversity and the subsequent loss of ecosystem services is still possible through intensified conservation efforts, but that window of opportunity is rapidly closing.

    It's science by press conference. Ehrlich hasn't been right about anything yet.

    Just one of the fundamental problems with this "study:" Fossil "species" are based on skeletal structure. Modern "species" are based on color variations, or spot patterns, or just because they're present on some land that you want to grab. They're not the same thing at all as fossil species. A great number of modern "extinctions" are just because the "species" never existed in the first place.

    It's comparing Mack Trucks and Matchbook Toys.

    Or put another way: GIGO
