I was just reading this article about the clothing industry and am shocked by the statistics. Most of us are buying and discarding clothes without a thought for the environmental impact, it seems.
Not so very long ago, we used to darn socks; put patches over threadbare elbows; add a strip of fabric to the hems of skirts and trousers when children grew too tall for them; make new clothes out of old ones etc.
Clothes used to be
a) much more expensive, relative to income
b) much higher quality
c) easier to mend, alter and repair
Everyone used to have far fewer clothes and kept them for several years. We need to try to return to that.
I think it will be very difficult to persuade people to buy fewer clothes, unless the government introduces measures to incentivise it. Some possibilities are a tax on clothes (similar to that on motor fuel, cigarettes and alcohol) and/or a tax on manufacturing of clothes. Both of these would increase the cost of buying clothes and might reduce consumption. Neither would be popular!
