This Land Is the Only Land There Is, Robinson Meyer, The Atlantic:

the human demand for food, meat, clothes, and warmth now consumes at least 25 percent of the net product of photosynthesis on land. The free-wheeling, far-reaching maw of our material metabolism—that thing we normally call the global economy—devours as many as one out of every three sugar molecules made by dirt-bound plants, on net … we have roughly hooked one out of every four of [plants] into our planetary system of consumption and speculative exchange

I was immediately reminded of my post on biomass: “humans … will harvest roughly 17 percent of what the biosphere grows this year”.

We are the aliens ravaging the Earth.
