the amount of production that the industry puts into churning hundreds of thousands of short-lived, unsustainable, fast products could have been used to create so many much more reliable and long-lived ones. imagine how much metal and silicon we wasted on iphones that die after a year or two when we could've made a phone that lasts for decades and is regularly updated/can be DIY modified.
or like, have you heard of fast fashion? so many jeans and hoodies, t shirts and bras that tear apart after a few months. so much material and labor wasted.
