POPSBark Beetles Kill Millions of Acres of Trees Hoping to keep their forests from completely dying, to earn money by selling dead and infected trees and to mitigate fire risks, landowners are scrambling to cut the pines. If enough are cut — up to 75 percent — it might leave some behind that, with less competition for water, can survive.

POPSBees Can Count To Four They really have a lot of the capacities that we so-called higher human beings possess. This, from an insect! Yet humans still treat animals as second-class citizens of this planet. Let's hope we still have bees around in the future. The bee die-off, or "colony collapse disorder" has still not been resolved. We need them, more than they need us, that's for sure.

POPSFossils tell of mass exodus from sea Creatures could develop some protection from the sun in the water, but the land was wide open, and predators were yet to get anywhere the efficiency of ocean based predators. They can understand why shelled arthropods had the protection to survive, but can't understand the survival of soft bodied things like worms and Molluscs? then perhaps they can explain why a slug like creature evolved a shell and branched unto the Snail genotype. i don't imagine life is safe anywhere for exposed slugs and worms, and solar radiation, particularly UV Light can accelerate development. and change. Perhaps they were moving to the place that was the least dangerous.
