How do oil spills occur?

उत्तर
Oil spills occur when large quantities of oil are discharged into oceans or seas during drilling operations, cleaning of tankers and leaks from pipelines and storage tanks, an accident or explosion on a tanker or an offshore drilling rig. Most cases of oil spills are almost always a severe case of man-made disaster as they cause long term damage to the ocean and its marine life.
