Millions of gallons of oil get spilled in water every year. This oil affects the oxygen availability in water and cause breathing problems and death of aquatic animals. This oil can also remove the waxy coating on the feather of seabirds. Without waxy coating, water sips inside the feather and make it hard for seabirds to fly. This inability of flying leads to drowning and death.
