This article explains pollution and water pollution in detail. The marine pollution is of three kinds - the land based, air based and by maritime transportation. The land-based pollutants are industrial wastes from the discharged untreated waters of the industries, fertilizer and pesticide run off from agriculture, municipals sewerage by the increase in population. Use of plastics contributes to the marine pollution in a bigger way. Accidental oil spills, and negligence of the transporters of the oil have a dangerous impact on aqua life. Jellyfish, birds, whales and other organisms eat the plastic mistaking it as food and die. Other smaller organisms entangle in the plastic rope and die. Swimmers are affected by infectious diseases and toxin-related illness. Alternatively, indigenous organisms that may have increased in number or virulence as a result of ecologic imbalance can cause negative health effects. Coral reefs and mangroves which are very much necessary for the environment are deteriorated by man in pursuance of economic development. They are to be protected.
