What is Oil Spill?
- Oil spill can be defined as “uncontrolled release of crude oil, gasoline, fuels, or other oil by-products” into environment. It can pollute land, air, or water; however, the term is mostly used for oceanic oil spills.
- They have become a major environmental hazard because of intensified petroleum exploration & production on continental shelves and transportation of huge amounts of oils in vessels.
Impact of Oil spills
- In ocean, oil spills are harmful to aquatic life as it prevents sunlight from penetrating into sea and reduces dissolved oxygen level.
- Crude oil damages insulating and waterproofing properties of feathers and fur of birds. Thus, it can decrease body temperature to below-normal levels.
- Oil spills can damage habitat and reproductive rate of animals.
