What human activities cause water pollution?
The causes of freshwater pollution are varied and include industrial wastes, sewage, runoff from farmland, cities, and factory effluents, and the build-up of sediment. Emissions from factories and vehicles are released into the air.
How can we prevent marine habitat destruction?
Ongoing efforts to safeguard ocean habitats include the creation of gigantic marine sanctuaries where development is curtailed and fishing is prohibited. Laws banning the dumping of sewage and chemicals into the ocean and policies that foster better stewardship of wetlands are having positive effects.
How can aquatic resources be protected and conserved?
One such option that has potential to protect freshwater environments from numerous threats is the use of freshwater protected areas (FPAs). FPAs are portions of the freshwater environment partitioned to minimize disturbances and allow natural processes to govern populations and ecosystems.
