Effect of pollution on dolphins

Where most of it comes from
Most of the pollution in the water comes from the boats. So if you own a boat try to keep it cleaned and in proper working order
Production and Manufacturing plants are biggest source of thermal pollution. When heated water returns to the river or ocean, the water temperature rises sharply. That's why animals in the ocean migrate
The warm water can also cause particular species of organisms to migrate to suitable environment that would cater to its requirements for survival. This can result in loss for those species that depend on them for their daily food as their food chain.
Water pollution happens when chemicals or dangerous foreign substances are introduced to water, including chemicals, sewage, pesticides and fertilizers from agricultural runoff, or metals like lead or mercury.
