And this is what's changing our ocean chemistry.

这就是改变我们海洋化学的原因。

Ocean chemistry was changing a bunch in the Ediacaran, so this kind of growth flexibility probably helped rangeomorphs survive.

埃迪卡拉纪的海洋化学发生了巨大变化，因此这种生长灵活性可能帮助了类胚生物生存。

And it's likely to be a lot less risky than changing the ocean's chemistry or engineering the ocean, because we'd actually be working with the natural systems instead of against them.

并且，相较于改变海洋的化学特性和海洋结构，利用海藻的风险更低，因为事实上，我们不是在和自然系统对抗，而是与它们合作。

But on top the local problem of nutrient runoff is the larger issue of global warming.Scientists believe the increase in prevalence and toxicity of Dinophysis is linked to changing ocean chemistry and warming waters.

但除了当地的养分流失问题之外，全球变暖也是一个更大的问题。科学家们认为，海龙藻的流行和毒性增加与海洋化学变化和海水变暖有关。

And a study out this week in Nature Ecology and Evolution suggests a reason why: they may have been among the first organisms to change their size and shape because of changing ocean chemistry.

本周发表在《自然生态学与进化》杂志上的一项研究提出了一个原因：由于海洋化学的变化，它们可能是最早改变大小和形状的生物之一。
