Data shows that dead zones in the oceans continue to increase. Researchers have identified 479 dead zones currently, with the largest ones near the US, Japan, and northern Europe. Fifty years ago there were only 49 identified ocean dead zones. The number has grown by over 977%. If the dead zones continue increasing at this rate, there will be over three thousand dead zones by 2060, the environmental group Ian Somerhalder Foundation (ISF) warned.
根据数据显示：海洋中的死亡区正在持续增加。研究人员目前已确认479处死亡区，最大的几个死亡区在美国、日本和北欧附近。50年前只有49处已确认的死亡区，这个数字以超过977%的比率成长。如果死亡区持续以此种比率成长，2060年前将有超过3千处死亡区，环保组织伊恩，萨莫海尔德基金会为此提出警告。
A dead zone is an area of water with less oxygen than normal, which kills sea life. Most dead zones are caused by global warming, fertilizer run off, overfishing, and pollution. These factors cause excessive algae growth. When the algae die, they use up oxygen in the water and release toxic gas.
死亡区是水中含氧量低于正常值的区域，该区域将扼杀海洋生物。大多数死亡区是由于全球暖化、肥料溢流、渔业过度捕捞以及污染所造成。这些因素造成藻类过度生长；然而当藻类死亡时，它们用尽水中的氧气并释放有毒气体。
Countless ocean organisms are lost to the dead zones each year, according to the famous magazine Scientific American. This greatly impacts the fishing industry and human populations that rely on seafood. The United Nations has promoted reducing industrial pollution to reverse the growth of dead zones.
著名杂志《科学人》表示：每年都有许多海洋生物因死亡区而丧命。这件事对渔业和依赖海鲜的人口影响甚巨。联合国已推动减少工业污染来逆转死亡区的数量增加。
