美国科学家近日发布研究报告称,因海底没有或者只有很少氧气无法支持海底鱼虾生存,由人为原因造成的墨西哥湾“死区”的面积大小已相当于美国康涅狄格州,形成了世界上第二大死亡区。这片“死区”形成的原因是因为过量营养物质从密西西比河沿岸的农场流出,并最终排入墨西哥湾。这些营养物质进入墨西哥湾后,促进了海藻等有机物过度生长,后者在生长过程中不断地消耗水中的氧气,最终使其他生物无法生存。毫无疑问,在农业生产过程中产生的农业面源污染 US scientists recently released a research report said that due to the sea there is little or no oxygen can not support the survival of fish and shrimp underwater, the Gulf of Mexico caused by man-made “dead space” has the size of the size of Connecticut, the United States formed the world The second largest death zone. This “dead zone” was created because of excess nutrients flowing from farms on the Mississippi River and eventually to the Gulf of Mexico. After entering the Gulf of Mexico, these nutrients promote the overgrowth of organisms such as seaweed, which continue to consume oxygen from the water during their growth, eventually rendering other organisms untenable. There is no doubt that the agricultural non-point source pollution produced in the process of agricultural production
