Re: Rethinking Nature Writing (in Los Angeles)

To dismiss LA as a nature-free wasteland is to ignore the stunning backdrop of the San Gabriel Mountains, arguably the most accessible wilderness in the lower 48.

Sadly, most Angelenos barely notice their natural bounty.

Re: Is the Swiffer Eco-Friendly?

I have yet to read on this post or the links that Swiffer contains any toxic chemicals.

I wouldn't dismiss the water-savings of regular swiffing versus regular mopping so easily.

I think this posting went a bit too far in criticizing Zaccai without providing much evidence to refute him.

Re: 1.2 MegaWatts: World's Largest Tidal Turbine To Be Installed

I'm a big fan of tidal power: No carbon, no nuclear waste, no toxic photovoltaic cells, and far less destructive than damming a river for hydroelectricity.

But I can see how these turbines might result in chopped-up whale meat.

I would prefer study of environmental impact compared to an assurance like "I think they can swim fast enough." Birds are pretty fast, and they get chopped up by wind turbines.

Wind turbine on top might not be a bad touch, but I truly doubt they could get another 1.2 megawatts that way. I doubt they could even add another 1% of that.

Still, because tidal turbines work only half the day (when tides are moving), complementing this with wind power is smart.
