One of the things that's happened because of this is that, since 1969, the country of Nigeria, or the part of Nigeria that pumps oil, which is the delta -- which is two times the size of Maryland -- has had thousands of oil spills a year.
这也导致了另一件事的发生。 自一九六九年起， 尼日利亚，或者说尼日利亚的产油区， 也就是三角洲--面积约为马里兰州两倍大小-- 每年发生数千起石油泄漏事件。
