Clothing and Pollution/Climate Change
I hope that I am doing my part. I might buy a new pair of jeans every two years or so. The old ones then last many more years as work clothes. Some of my Tee shirts are over 20 years old and I still have underwear with sown in tags. All of my work clothes get multiple days of use before washing, but my wife is one who needs to launder anything that has been worn if only for an hour.
Fast fashion is the issue, coupled with Americans (and a better part of the world) being consumers for the sake of consuming: people thinking they need to replace or buy new trends every season instead of having basics that last year through year, and buying items that won't last for more than a season or two. I don't think as nudists we'll see a day where we stop buying clothes because being clothes-free is a norm - too much change in societal beliefs that have been passed on through generations, so what we can do is try to be smarter consumers about what we buy, not buy just to buy, and be better stewards of the earth while we're here.
There is not enough demand for used clothes and/or clothing materials, hence there is very little profit in recycling clothing. I mean, there are far more consumers buying soda, beer, and canned food. Yet, there is a great demand for scrap metal and glass that we have a profitable way to deal with the waste.
If we had a profitable way to deal with all the unwanted clothing in the world, then there would no longer be a problem with people buying so much clothes.
Many charities are often looking for used clothing in good condition, so anything that is just out of style could be donated.
Doesn't help with what to do with clothing that is really worn out.
One local one runs an annual drive called "Operation Empty Closet" encouraging people to clean out their closets and donate anything in good condition that they do not want.
My closet is already relatively empty, and I suspect the same is true of a lot of other people on this site.
