Oil Pollution
Akopọ
The world still runs on oil, and every day enormous quantities are drilled from beneath the seabed and carried across the oceans in giant tankers. Most of it arrives safely. But when something goes wrong, the results can be catastrophic: a single spill can blacken hundreds of kilometres of coast, kill countless seabirds and fish, and damage ecosystems for years. Oil pollution is one of the most visible and emotive of all environmental disasters.
In this lesson you will learn what causes oil to enter the sea, how a spill spreads and devastates marine and coastal life, and the two sides of the response: preventing spills in the first place through better ships and rules, and minimising the damage when one happens, using booms, skimmers, dispersants and controlled burning. Named disasters such as Deepwater Horizon will make the scale of the problem real.
