2.1 Shipping activity can constitute an environmental
hazard to the marine environment in general and consequently even
more so to environmentally and/or ecologically sensitive areas. Environmental
hazards associated with shipping include:
-
.1 operational discharges;
-
.2 accidental or intentional pollution; and
-
.3 physical damage to marine habitats or organisms.
2.2 Adverse effects and damage may occur to the
marine environment and the living resources of the sea as a result
of shipping activities. With the increase in global trade, shipping
activities are also increasing, thus including greater potential for
adverse effects and damage. In the course of routine operations, accidents,
and wilful acts of pollution, ships may release a wide variety of
substances either directly into the marine environment or indirectly
through the atmosphere. Such releases include oil and oily mixtures,
noxious liquid substances, sewage, garbage, noxious solid substances,
anti-fouling systems, harmful aquatic organisms and pathogens, and
even noise. In addition, ships may cause harm to marine organisms
and their habitats through physical impact. These impacts may include
the smothering of habitats, contamination by anti-fouling systems
or other substances through groundings, and ship strikes of marine
mammals.
