How oil pollution affects the Mississippi and Niger deltas
Oil spills are leakages of petroleum onto the surface of a large body of water. Oil spills can happen in rivers, bays, and the ocean and are most often caused
by accidents that involve pipelines, tankers, and drilling rigs. These accidents can happen due to natural disasters like hurricanes or storm surges, but also due to
terrorists and illegal dumping, or people making mistakes and being careless.
