Black dots show where dead zones have been observed, but their size is unknown.───黑点代表那些已经观测到的但面积还未确定的死亡区域。

Synthetic fertilisers eventually run into rivers and oceans, creating "dead zones".───人造化肥农药最终流入河流和大海，富集成为死亡区域。

Hundreds of the world's coastal regions have dead zones.───世界上有着死寂之区的海岸地带有数百处。

Dead zones form when big balloons of phytoplankton at the surface trigger large quantities of organic matter, which then sink to the bottom.───当浮游植物大量爆发时，在其表面会触发大量的有机物质聚集，然后（浮游植残骸）下沉到水底，死亡带就会形成。

Such fertilizer leaching is responsible for dead zones across the world, like the one at the mouth of the Mississippi River currently.───这些肥料的浸出是造成世界多个死亡区的罪魁祸首，比如眼下的密西西比河口。

Pollution-fed algae, which deprive other living marine life of oxygen, are the cause of most of the world's dead zones.───富营养藻类夺走了海洋生物的养分，是全球大部分死区的成因。

Marine dead zones form when nitrogen and phosphorus pollution concentrates in near-coast waters through a process called eutrophication.───氮，磷污染通过被称为富营养化的这个过程，在近海岸水域集中泛滥，从而形成海洋死区。

This can trigger toxic algal blooms and a rising number of oxygen deficient 'dead zones'.───这可以导致有毒的赤潮出现，使缺氧“死亡区”的数量不断增加。

Many human activities on land trigger the seasonal appearance of dead zones. Fertilizers run off lawns and farmland.───陆地上许多人类的活动引发季节性死亡区的出现，从草坪和农田中流失的肥料。

Oceans were rapidly warming and acidifying, water circulation was being altered and dead zones within the ocean depths were expanding, said the report.

The Mississippi River watershed drains directly into the Gulf of Mexico, where dead zones frequently occur.

"Dead Zones" occur around the world, from the Chesapeake Bay to the Baltic Sea.

Massive releases of methane from arctic seafloors could create oxygen-poor dead zones, acidify the seas and disrupt ecosystems in broad parts of the northern oceans, new preliminary analyses suggest.

"Dead zones" with almost no oxygen already make up around 2 per cent of the oceans by area, and they could expand seven-fold.
