We humans think we're so smart: We figured out how to farm and cultivate, and no other species did. I say, big whoop -- those systems also create problems, from cow-fart pollution to overproduction. To lots of people, that's just the way it has to be. But what if hunter/gatherers had had such a lazy attitude?
Luckily, many academics, farmers, environmentalists, and others are putting their giant brains together to come up with a system that might make sense for the entire planet. The idea is to emulate healthy natural ecosystems. At Permaculture Fundamentals, a full-day seminar, ecological biologist David Blume explains the theory, starting at 9 a.m. at Strybing Arboretum & Botanical Gardens, Ninth Ave. & Lincoln, Golden Gate Park, S.F. Admission is $90; call 661-1316 or visit www.strybing.org for required preregistration. -- Hiya Swanhuyser

Feel the mist starting at 11 a.m. at Mount Tamalpais State Park (exact meeting location revealed to those who reserve a spot), 801 Panoramic Hwy., Mill Valley.

Being Green Take the environment home
When your home needs sprucing up, you could visit the nearest big-box retailer to buy particle board (full of formaldehyde and other dangerous chemicals), traditional carpeting (which emits a shocking amount of greenhouse gas carbon dioxide during its tenure on your floor), and other environmentally unfriendly products. Or you could renovate your home with ecologically sustainable fittings from energy-efficient light bulbs to flooring made of recycled tires or salvaged lumber.
Jennifer Roberts, author of the how-to book A Good Green Home of Your Own, along with special guest speakers, spell out the finer points of green design at "Good Green Homes: Creating Better Homes for a Healthier Planet," starting at 6 p.m. at the Mechanics' Institute Library, 57 Post (at Market), S.F. Admission is free-$5; call 393-0101 or visit www.milibrary.org. -- Joyce Slaton
