北极下起“塑料雪”！人间最后一片净土也面临威胁……

人类每周摄入微塑料的量=一张信用卡

微塑料是任何长度小于5毫米的塑料碎片。

Microplastics are not a specific kind of plastic, but rather any type of plastic fragment that is less than 5 mm in length. They enter natural ecosystems from a variety of sources, including cosmetics, clothing, and industrial processes.

微塑料不是一种特殊的塑料，而是任何长度小于5毫米的塑料碎片，它们通过各种来源进入自然生态系统，包括化妆品、服装和工业过程。

ecosystem ['ekoʊ.sɪstəm] n.生态系统

不仅是自然界，人类在生活中也会摄入大量微塑料。

有研究指出，从全球范围来看，我们每周平均摄入5克（微）塑料，相当于一张信用卡。

Globally, we are ingesting an average of 5 grams of plastic every week, the equivalent of a credit card.

其中，饮用水是人类微塑料摄入的最大来源。

It found that the average person consumes as many as 1,769 particles of plastic every week just by drinking water—bottled or from the tap.

研究发现，仅通过饮用瓶装水或自来水，人类平均每周就会摄入1769个塑料微粒。

虽然现有研究仍然无法确定微塑料会对人体会造成什么危害，但微塑料的大量存在仍然值得引起我们的警惕。

Plastic is not a particularly harmful material, however there is the potential that it does significant harm. Further research is needed into the impact of long-term plastic exposure. But if microplastics are shown to damage human health, it will be very difficult to remove them from the environment.
