It's a nonsensical argument. Why would you throw a jacket out because the zip doesn't work, when you can easily get it replaced or repaired? My home town of Reading has seen two independent tailors set up within five minutes of each other. Both are doing a roaring trade. It seems like we do understand the notion of sustainability.
It's sad that we even have to outsource simple repair work, though. It isn't that long ago that most families had someone that knew how to use a needle and thread. These are essential life skills that seem to have been forgotten over the course of just a generation.
Fortunately, there are people willing and ready to teach us the error of our ways. In a video put together by the excellent folk at Fashion Revolution, knitting guru Katie Jones takes us through the easy ways we can repair or retask tired garments and bring them back out from the back of the wardrobe. It's an inspiring watch, and Katie's enthusiasm is clear.
