We have to accept that we are the Earth's most active agent of change and that we are not in control. Things get out of hand, we lose interest, we cannot manage every outcome. Amid the chaos, there are lovely things and terrible things, there is squill and there is buckthorn. We disparage the buckthorn and admire the squill, while doing little about either or choosing one over the other because it charms us. This weakness keeps us interesting. We despise buckthorn because it is so bland, so visually unpalatable, as much or more than for its aggressive growth. Then, we justify time consuming, expensive, aggressive eradication with ennobling gestures toward native purity.
The radical streak in Nature abhors a museum. We are nature. The way we change the land is nature while we are here, and for some years after. We are the buckthorn and the squill amongst the oaks and the orchids.
