Fashion is a deeply irrational market that preys on the worst of human nature. There are companies selling cotton t-shirts with a logo on them for 500 dollars. You might say ok, if people are dumb enough to buy that then that's not my problem. So now there are companies creating the environmental cost of destroying viable products just to sustain this kind of grifting.

On top of that I think that society, as a general principle, should demand more product transparency in the form of regulation. What are the actual environmental costs of a certain product? Where are the components coming from? What kind of production process did that industry adopt? All this should be clear in the description of a product.

The way things are right now the incentives are geared towards trying to industrialize and sell the worst kind of product for the highest price and offload to society as an externality the environmental and social costs of doing so.
