When production processes threaten or cause damage to the environment, the cost of necessary environmental measures should be borne by the producer and not society at large, giving incentives to reduce pollution.

Pollution

The introduction by man, directly or indirectly, of substances or energy into the marine environment, including estuaries, which results or is likely to result in such deleterious effects as harm to living resources and marine life, hazards to human health, hindrance to marine activities, including fishing and other legitimate uses of the sea, impairment of quality for use of sea water and reduction of amenities (UN Convention on the Law of the Sea 1982).
