Humans reached a point, a long time ago, when they stopped behaving like other animals--a distinct human ecosystem, the city, was born
Outside the city, we still foraged and hunted like other animals do--it was in cities that agriculture and all other technology emerged
The city is still a half-born ecosystem, still in development, far from ideal--what would it look like if finished?
In an ecosystem, most waste products from one part are reused in another part; the only real "inputs" are water and sunlight
That is, a rainforest doesn't need anything shipped in from a desert, and vice versa--everything they need is in the soil, + water and light
Not actually true. The Amazon imports 22,000 tons of minerals in the form of wind-blown dust from the Sahara desert each year.
I was wondering if someone would bring this up...either re: windblown dust, or glacial/riverine sediment
If it help you can picture the stratosphere like a giant cargo train network. :)
