Kinds of Pollution
Pollution is classified into three categories: air pollution, water pollution and sound pollution.
The type of pollution dictates which animals are affected. Most often, classified pollution types affect animals in all parts of the environment. An example of this would be how water pollution has negative and detrimental consequences on birds.
Air Pollution
The caustic emissions from vehicles and manufacturing processes are responsible for the majority of air pollution in the atmosphere. These kinds of emissions change the natural balance of gases in our air. Deforestation plays a major role in the contribution of air pollution because with less trees, the oxygen in our atmosphere is diminished, leaving the detrimental gases to dominate. Live trees eliminate destructive carbon dioxide from the air and create an environment necessary to house forest creatures.
Air pollution is directly responsible for the hole in the ozone layer. The ozone layer, the upper-most portion of the earth's atmosphere, protects the planet from the sun's destructive ultraviolet rays.
The abundance of carbon dioxide and methane, known as greenhouse gases, create a barrier around the planet, trapping in the sun's heat. Called global warming, this is responsible for melting the polar ice caps. Prey animals of the North and South polar regions are losing hunting grounds. The animals that count on the ice for life support experiencing widespread mortality.
Water Pollution
Water pollution is a direct result of industrial and domestic waste being disposed in our rivers and oceans. These hazardous wastes make our soft water hard by introducing large amounts of magnesium and calcium salts. The contaminated water becomes lethal and unable to support many animal and aquatic species. The earth's fresh water supply is only 3 percent of the total available water. Pollution is gradually lowering that number every year.
Sound Pollution
The majority of sound pollution comes from industrialized activity. Other examples of sound pollution include loud music, vehicles, airplanes, railroads, amplified music and construction work. According to the Environment and People website, sound pollution, also known as noise pollution, does irreversible damage to the ears and sensory perception of all living animals. Noise pollution disturbs the natural existence of the planetary ecosystem by forcing animals to relocate, which disrupts their natural disposition. For instance, sea turtles return to the same shoreline year after year to lay their eggs. Human-generated noise will force a sea turtle to seek other accommodations or terminate her egg-laying procedure.
