While my city has destroyed the environment of the majority of animals, there are some notable exceptions. Crows, ravens, pigeons, rabbits, squirrels--all of these animals seem to flourish in a city environment. They live in a much higher concentration than the animals you see outside of the city. Over time I think the story is going to change. These are just the first animals that have adapted well to a city lifestyle, and they will be selected for as time goes on. If we could lose our obsession with monocultures, i.e. grass lawns, I think a lot of the world's biodiversity could be preserved. Are there any notable startups devoted to making our cities more habitable for plants and animals?
