Antarctica's plastic threat 科学家称塑料污染已威胁南极海域 本集内容 Antarctica's plastic threat 科学家称微塑料污染已给南极海域造成威胁 学习要点和“the environment 环境”有关的词汇 边看边答 Scientists use a 'manta' to collect samples. What is it? This is the most remote continent on Earth. It looks pristine, but today there's new evidence that microplastics are now reaching even these waters and perhaps more disturbingly there is also pollution from airborne chemicals in freshly fallen snow. 这是地球上最偏远的大陆。它虽然看起来一尘不染，但现在新证据显示，微塑料已蔓延到了这片海域，也许令人更加不安的是，在刚落下的雪片中也含有弥漫在空气中化学污染物。 We were with scientists on board a Greenpeace ship in January as they began testing waters off the Antarctic Peninsula. Very little data exists. It's a question of picking a tiny bit of the Southern Ocean and lowering in a manta, a trawling device. Any microplastics should find their way into the net. 今年一月，我们和一组着手测试南极半岛周边水质的科学家一起登上了绿色和平组织的一艘船。相关数据微乎其微。问题的关键是选南冰洋中很小的一部分，把形似蝠鲼的拖网装置放入水里。这样，任何微塑料成分都会被收入网中。 |
