Tin 'tức không chịu được'

cứt toàn vi hạt nhựa

EVERY MINUTE, A dumptruckful of plastic plops (rơi tõm) into the world's oceans (đại dương). That's eight million metric tons every year. Once waterborne, whatever doesn't wash ashore eventually breaks down into itty bits (nhỏ xíu). The puniest pieces—the ones smaller than 5 millimeters wide—are called microplastics, and their fates are numerous. Some glob onto an Alaska-sized gyre (vòng xoay)d of plastic debris (mảnh vụn) swirling in the Pacific Ocean. Others sink to a variety of depths, according to their densities, perfusing (đổ khắp, làm tràn ngập; truyền dịch (vào cơ thể)) the world's waters. Still others get ingested (ăn vào bụng) by marine life, including fish and shellfish, which are in turn ingested by other animals, like birds and humans.

All of this is a mess, from an ecological (sinh thái) perspective. But it's that last bit—the microplasticine infiltration (sự thâm nhập) of food webs—that worries not just ecologists but gastroenterologists (bác sĩ chuyên khoa dạ dày-ruột). If microplastics are invading the things we eat, it's possible that they're invading our stomachs (dạ dày) and intestines (ruột), too. But while the matryoshka-nature of food chains certainly suggests that human guts harbor microplastics, nobody's really bothered to look in a systematic way...

  1. Guess what! There are a lot of "plastic" people in the world, so it (sort of) makes sense.

    And then, then are celebrities who have "plastic" surgery.

    None of it gets recycled, does it?
