Halden explains thus "Today, there's a complete mismatch between the useful lifespan of the products we consume and their persistence in the environment." ie consider the 25 minutes your grocery shopping spent in that plastic bag you chose to put it in to carry it home vs the potentially immeasurable time that the microplastics that plastic bag will break down into in a few years will be in existence, causing harm. What seems sensible? Use the plastic bag? Or don’t use the plastic bag? There are bamboo, linen, paper etc options that work just the same and can be reused.
