This document discusses marine plastic pollution. It begins by noting that oceans cover 71% of the Earth's surface and play an important role in the planet's chemical and biological balance, but that human activity has degraded ocean habitats and caused mass deaths of marine life. It then defines marine pollution and lists various pollutants like sewage, pesticides, plastic waste, and oil as well as their sources and effects. The document concludes by emphasizing the importance of oceans for food and ecosystems and the need to prevent pollution and protect marine environments.

3. INTRODUCTION
 Oceans cover about 71% of the Earth’s surface.
 They play an important role in the chemical and biological balance of the life
on the earth.
 They are vital to our food security, commerce and transportation.
 But human activity has troubled the health of oceans.
 The habitats of marine mammals and fish have been degraded severely, with
pollution responsible for the mass deaths of fish, mammals and corals.

4. MARINE POLLUTION
 It is defined as the discharge of waste substances into the sea resulting in
harm to living resources, hazards to human health, hindrance to fishery and
impairment of quality for use of sea-water.
 Marine pollution is associated with the changes in physical, chemical and
biological conditions of the sea water

5. POLLUTANTS: SOURCES AND THEIR
EFFECTS
 Pollutants can simply define as the materials which cause pollution. The following
are the important pollutants that cause the marine pollution.
 Sewage
 Pesticides
 Plastic wastes
 Metallic wastes
 Oil
 Sediment plumes (by deep sea mining)
 Heat
 Radioactive waste

6. PREVENTION AND CONTROL OF MARINE
POLLUTION
 Removal of phosphorus by electrolysis.
 Adopting appropriate methods to remove heavy metals from the marine water.
 Radioactive wastes can be removed or reduced by the ion-exchange techniques,
precipitation of radio-nuclides.
 The impacts of deep sea mining can be minimize or reduced by using proper
mining techniques.
 Creating awareness on marine pollution.
 Local communities near sea must protect sea.
 Management by government
 Incentives must be offered for conservation.
 Industrial units should be equipped with pollution control instruments

7. CONCLUSION
 Oceans cover the earth’s surface about 71% and play an important role in the
chemical and biological balance of the life on the earth.
 These are rich with marine resources like minerals, oil and marine life and
the sea food supplies meet a substantial food requirement of the world’s
population.
 If the marine life affected by the pollution and if they carry pollutants in its
biomass, the human population may get the impact while consuming such
resources. Hence it is necessary to aware about the marine pollution, and to
protect the marine water from the pollutants. So, necessary to prevent and
control this pollution.
 Let us save our oceans and the huge marine ecosystem.
