But I take issue with this quote:
> The holy grail of sustainability is a closed-loop system. “With leather, nature has created its own sort of closed-loop system,” says Hustvedt. “The carcass of an animal can decay in the ground and nurture plants that are eaten by the next generation of animal.”
Yes, and that's great for the environment if you look past all of the environmental harm created by raising the animals needed for that leather. But CO2 and methane production, deforestation, runoff from factory farms... all of these consequences take a serious toll on the environment.
There are a lot of bad choices for clothing - cotton is notorious for requiring a lot of pesticides to grow as well. And that many clothes are made in sweatshops in poorer countries, not uncommonly made with child labor. And it's all shipped across the ocean using fossil fuels.
It doesn't have to be this way though.
