I am the nursery of the sea.

我是海洋生物的栖息地。

And then the deeper you go, you find less and less.

然后越往深处去，你会发现这些海洋生物会越来越少。

Their methods do not attempt to estimate the actual biomass (the amount of living biological matter) of fish species in particular parts of the ocean, but rather changes in that biomass over time.

他们的方法不是为了试图估算特定区域的海洋中实际动物总数（活着生物的总数），而是研究单位面积中海洋生物数量的变化。

Dicing with death, they breathe air pumped through hose pipes in a desperate bid to catch the last remaining sea life.

渔民们潜入海底以死相搏，他们呼吸通过软管抽过来的空气，孤注一掷，来捕捉仅存的海洋生物。

That means a higher proportion of what is in the sea is being caught, so the real difference between present and past is likely to be worse than the one recorded by changes in catch sizes.

这意味着同50前相比可以捕获更多的海洋生物，所以现在和过去的真正差距可能会比之前在捕获区记录的数据所显示的更糟糕。

The archipelago is celebrated for its rich marine life and underwater coral reefs.

这个群岛以其丰富的海洋生物和水下珊瑚礁而闻名。

While it provides no impediment to water traffic and marine life can pass through freely, it also catches plastic waste of all sizes.

它不仅不会妨碍水上交通，海洋生物可以自由通行，也能收集各的塑料垃圾。

I watched an excellent program about the symbiosis of sea creatures.

我观看了一档有关海洋生物共生关系的优秀节目。

These creatures are eaten by the fish that we eventually consume.

这些海洋生物会被鱼吃掉，而我们最终会把鱼吃掉。

And environmentalists fear its arrival could endanger other types of marine life.

环保主义者担心它们的到来会危及其他类型的海洋生物。

And Marine life experts believe a harmful algae bloom is to blame.

海洋生物专家认为，有害的藻类量繁殖是罪魁祸首。

And anything that eats in the ocean will inadvertently eat plastic.

所以，海洋生物总会无意中吃到塑料。

This in turn would damage sensitive marine life like coral and microscopic organisms, and lead to things like bleaching and mass die-offs.

这进而会危害敏感的海洋生物，如珊瑚和微生物，并导致它们褪色和规模死亡。

It's incredibly rich marine life we're seeing here, It's a sort of a living carpet.

我们在这里看到的海洋生物非常丰富，就像一块活地毯。

Were they interested in the marine animals? Not particularly.

它们会海洋生物感兴趣吗？也没有。

But just a million years after that, four out of five of the world’s marine species

五分之四的海洋生物都消失了。

So we don't have anything that can entangle marine life and what happens is that the current flows underneath it while the plastic which floats will remain in this zone in front of the clean-up system.

因此，没有任何东西会缠住海洋生物，水流在下方流动，而漂浮的塑料将固定在该系统的前方区域中。

So jellyfish and other marine life are easier to spot.

所以更容易发现水母和其他海洋生物。

This sea creature would have been a totally unfamiliar sight in the inland regions where the image is found and may have been the inspiration behind the early paintings.

内陆发现了这完全陌生的海洋生物的图像，同时它可能激发了早期绘画的灵感。

The waters off Ecuador are believed to hold the world's largest population of what?

世界上最多的什么海洋生物位于厄瓜多尔附近海域呢？
