南希·拉巴莱斯: 墨西哥湾的“死亡区”

墨西哥湾的“死亡区”

海洋学专家南希·拉巴莱斯持续研究了墨西哥湾的“死亡区”——很不吉利的名字，这里的水中没有足够的氧气供生命存活。墨西哥湾拥有世界上第二大的死亡区，除了杀死鱼类与甲壳类动物以外，它也终结了这里的渔业活动。拉巴莱斯告诉了我们“死亡区”的形成原因，以及我们怎么改善这个不利局面，来复原美国的这一自然宝藏。

Oxygen-starved "dead zones" in the Gulf of Mexico now cover an area as large as New Jersey, killing off fish, crabs, and entire fisheries. These zones are fueled by runoff from Midwest farms, where triple the nitrogen and double the phosphorus now flow into the Mississippi River compared to the 1950s. Changing agricultural practices and personal choices can help reduce this pollution. The challenge is bridging science with policy and inspiring collective action across the country.
