Nature doesn't care about you. But that being said, the birds and insects, even the occasional mammal in Quarry Lakes park, are interested - they notice you more than you notice them. The geese just shit and warily walk around you; sparrows curious, hop nearby and then dart into the bushes or up high on tree branches; ground squirrels perch on their hind legs and gaze at you with their big black eyes, always ready to dart into their burrows; dragonflies hover around, often stopping to hover just in front of you, just as hummingbirds often do. If you stop and let them. A month ago or so I saw a red-tail hawk, with a freshly caught rattlesnake in its beak, perched on a tree branch maybe two feet off the ground - uncommonly low for hawks, who prefer to espy their surrounding from on high. Nature will talk to you, if you have the time and awareness to listen. And if you keep your ear buds out. I've climbed, hiked, backpacked and trekked all over the world for decades; never once have I done so with earbuds, or earphones on. I prefer the sounds of my surroundings.
At any rate, the idea "nature" is simply a human construct; there is nothing natural about it. Just like "organic" food; its a shared idea, or not-so-shared, a series of subjective ideas about a space, which satisfy some objective criteria: no concrete? Check. No gardeners or leaf blowers? Check. Are the animals and plants winning? Uhm ... looks like it. If you live in the city, Quarry Lakes looks natural. If you've just come back from a back-country trip to the Sierras, its very much an urban park.
I respect the animal's and plant's rights to existence, and that they are equal to my claim.
