Answer 2

Answer:

Yes, it is.

Explanation:

Dumping involves depositing all the waste materials from factories and industries, tankers and ships and sewerage waste materials into the oceans and seas. Some of the materials emitted by the industrial wastes and sewage wastes contain materials like mercury, cryolite and DDT. Certain industrial wastage also includes radioactive materials. Even small amounts of these substances tend to have negative effects. The scale and the magnitude of the ocean dumping are not just vast but are so huge, that our entire civilisation could be wiped out with the intensity of careless dumping. The discharge of ballast water also causes the problem by way of ocean waste.
