SAVE THE FISHIES! About the key questions


Hey guys, i've got something to add in about the key questions.

1) What are the causes of water pollution?
Pollutants being emitted directly into a water body results in a "point source", such as a pipe from an industrial facility leaking toxics directly into the water. Pollutants being indirectly transported to the water such as run off from fertilizers flowing in to a larger body of water by rain results in a type of polution called "nonpoint source". Another cause of water pollution happens when oil, gasoline and additives gets spilled due to a leak in a major oil tanker. This usually gets a lot of coverage and press due to it's effects on marine animals, local fisherman and coastal businesses. Oils can also seep into the waterways through the groundwater as a result of a leak or small spill.
For additional the causes of water pollution are:

• Chemical and industrial processes that produce waste that is injected into deep groundwater sources

• Sediment build up as a result of clear cutting

• Personal care products and household cleaning products such as bleach, fabric softener, lotion, perfume and hair dye

• Sewage

• Heat from power plants that causes water pollution by killing fish and marine organisms.

• Carbon Dioxide which causes acidification in oceans
