Ancients responsible for "serious damage" along coasts

Yesterday, we learned that ancient people may have kicked off global warming with the advent of agriculture. Now there's evidence early man did some "serious damage" to costal ecosystems" tens-of-thousands of years ago with "fairly simple technology." (New York Times)

For example, research indicates early man wiped out otter populations around the Channel Islands (off Los Angeles), which led to a spike in urchin, which took out underwater kelp forests.

So what? It's important to know what costal ecosystems were like before man came in and messed everything up so we know, for example, what to shoot for with preservation efforts. If not, "efforts to preserve or restore important habitats may fail."

I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
