If you log onto Temu, you might see something like a fuzzy rug that normally costs $85 being advertised for $3. This should hopefully send a signal to your brain: This is not the same quality that the $85 rug is made of.
With plenty of synthetic materials being manufactured by Temu, this type of low-quality stuff is terrible for the environment. According to the National Library of Medicine, synthetic fabrics are “more polluting than natural textiles because they do not decompose easily.”
