Oil leakage and petroleum products into sea water due to accidents of ships and oil tankers or leakage of pipe lines and storage tanks. They occur when oil is being produced from offshore well and may happen due to transportation by pipes and tanks, oil refineries, petrochemical plants, etc.
Damage caused by oil spills :
- Fish, birds, reptiles, and amphibians living in cannot breathe and die. The oil penetrates the bird's feathers and they cannot Toy, and affect their insulation and damages the reproductive system.
- It interrupts the food chain which may cause the extinction of species.
