This document discusses various types of marine pollution including direct discharge, deep sea mining, ship pollution, plastic debris, and oil spills. It describes the sources and effects of these pollutants, which can include hazards to human health, hindrance of marine activities, and damage to wildlife. The document presents solutions like correction and prevention methods. Overall, it provides an overview of the definition, causes, impacts, and potential solutions to the issue of marine pollution.

3.  The term 'pollution' describes the occurrence and
inputs of wastes and the impact of these wastes
on the environment.
 MARINE POLLUTION (UN definition) –
“The introduction by man, directly, or indirectly,
of substances or energy to the marine
environment resulting in deleterious effects such
as: hazards to human health, hindrance to marine
activities, impairment of the quality of seawater
for various uses and reduction of amenities.”

4.  Air pollution
 Water pollution
 Soil pollution
 Noise pollution
 Thermal pollution
 Marine pollution

5. o Direct discharge
o Deep sea mining
o Ship pollution
o Plastic debris
o Oil spill

6. Pollutants enter rivers
and the sea directly from
urban sewerage and indus
trial
waste discharges, someti
mes in the form
of hazardous and toxic
wastes.

7.  Deep sea mining is a relatively new mineral retrieval
process that takes place on the ocean floor.

8.  Ships can pollute
waterways and oceans in
many ways. Oil spills can
have devastating effects.
 Discharge of cargo residues
from bulk carriers can pollute
ports, waterways and oceans.

9.  Marine debris is mainly
discarded human rubbish
which floats on, or is
suspended in the ocean.
 Discarded plastic bags, six
pack rings and other forms of
plastic waste which finish up
in the ocean present dangers to
wildlife and fisheries.

10.  An oil spill is the release
of a liquid petroleum
hydrocarbon into the
environment, especially
marine areas, due to human
activity, and is a form of
pollution.

11.  Contact with crude oil or refined fuel oils. This causes
feathers to collapse and matt and change the insulation
properties of feathers and down.
 The food searching instincts such as diving and swimming
are inhibited.
 Severe irritation of the skin.
 reduced reproduction ability

12. Two main methods
 Correction – costly and time intensive
 Prevention – requires attitude changes
Coastal Scientists believe that prevention is better
than cure since the effects of marine pollution may
be irreversible and we may therefore be creating
everlasting damage to the marine ecosystem.
