中略
Microplastics, which are smaller than 5 millimeters in diameter, come from plastic waste in the sea or other locations that are broken down by weather, degradation and wear and tear. Researchers warn that their pollution is spreading globally. Microplastics have been detected in the bodies of marine species and drinking water worldwide.

今回取り上げるのは、wear and tear です。直訳すると「着ると涙」ですが、これでは意味が通じないため調べてみました。
LDOCEには、“damage caused by continuous use over a long period” とあり、例文として“check the equipment for wear and tear”とありました。『ウィズダム英和辞典』には「（日常の使用による）傷み、劣化、消耗」と載っており、“normal wear and tear” で「通常の使用による傷み」となるそうです。
記事では “weather, degradation and wear and tear” で、「風化や劣化、傷み」と解釈できると思われます。（Otoyo）
