Detailed explanation-1: -Crude oil pollution occurs when the liquid form of petroleum leaks into an ecosystem due to anthropogenic (human) causes. Oil pollution most commonly occurs in the form of oil spills. Oil spills release a large amount of oil into marine and coastal waterways, with devastating consequences.
Detailed explanation-2: -Kemp’s ridley, green, loggerhead, hawksbill, and leatherback sea turtles were affected. Oil on turtles restricts their movements, causing them to become exhausted, exposing them to harsh temperatures, and making them vulnerable to predators.
Detailed explanation-3: -Oil destroys the insulating ability of fur-bearing mammals, such as sea otters, and the water repellency of a bird’s feathers, thus exposing these creatures to the harsh elements. Without the ability to repel water and insulate from the cold water, birds and mammals will die from hypothermia.
