(Apologies to Joyce Kilmer.) As someone absolutely passionate about being a truly green greenie — as mentioned before, if you looked at our house from Google Earth, you would barely see its roof amid all the trees and shrubs we’ve allowed to grow around and over it — I’m skeptical about Hizzoner‘s new “WE (HEART) TREES” campaign, lovingly (and mostly uncritically) previewed in the P-I and Times this morning. One even more fabulous way to slow tree loss would be to apply tougher standards to the rampant infill that’s under way in areas like ours. On the slopes over Lincoln Park, in the past few years, we’ve seen acres of greenery fall to developers’ backhoes (here’s just one example), replaced by oversized houses (do 2 or 3 people really need 3.5K sf?). How about we save a little more greenspace than just what’s left in our parks? Dare to look at an “undeveloped” lot and consider that maybe its highest and best use is to stay “undeveloped.” There’s more to “environmentally critical” than streams and wetlands.
