It sounds like you are taking this for granted and something that can't be changed. In fact there are a lot of initiatives and companies that work on reducing the footprint, using sustainable sources of cotton, paying fair wages, using less harmful dying methods and filtering the water used in production. If you are interested in the topic I'd suggest to start with https://en.wikipedia.org/wiki/Sustainable_fashion.

As for the green washing, there are probably better sources ([1], [2]) for that but you'll find enough if you do a little research yourself.
