The Flint water crisis developed after the City of Flint, Michigan attempted to save millions of dollars by changing its water source from Lake Huron to the Flint River. The Flint water crisis resulted from the Flint River having higher chloride concentration and was more corrosive than the water from Lake Huron. As a result, lead poisoning in water was leaching through the aging pipes.
On July 19th, 1979 two oil tankers collided in the Caribbean sea just off the island of little Tobago causing a widespread oil disaster. Twenty-six members of the crew were killed and over 280,000 tons of oil spilled into the sea. At the time, this collision was considered the worst oil disaster in history and to this day remains one of the few events where oil-tankers have collided with each other.
