保利教授和泽勒博士认为，我们的海洋出现这些问题，正是因为我们太爱吃健康的金枪鱼的缘故。

The fish is popular not just for its taste but for its health benefits – it is rich in omega-3 fatty acids, which aid heart health.

金枪鱼受欢迎不仅是因为它的美味，还因为它给人体健康带来的益处——金枪鱼富含有益心脏健康的欧米珈-3脂肪酸。

But whilst sushi has a reputation for being low in calories and high in nutrients, we may have overestimated its health value.

不过尽管寿司以低热量高营养著称，我们可能高估了它的健康价值。

In advance of a lecture at the Zoological Society of London lately, Professor Pauly revealed he believes most high-street restaurants serve sushi that contains plastic microbeads, the controversial tiny particles often found in face-scrubs and beauty products.

日前在伦敦动物学学会讲课前，保利教授透露说，他认为多数商业街餐厅卖的寿司里含有塑料微珠，这种有争议性的小颗粒物常见于磨砂洗面奶和美容产品中。

“Microbeads are poison pills which soak up all the pollutants and they are consumed by little fish which are then eaten by tuna,” Professor Pauly explained.

保利教授解释说：“这种小微珠就是毒药丸，它吸收了所有的污染物，先被小鱼吃掉，然后小鱼再被金枪鱼吃掉。”
