WAYS TO PREVENT POLLUTION IN ECOSYSTEM

Recycle


  • Recycling is one of the best ways to keep pollution under control. This is because a great deal of ecosystem pollution comes from discarded waste materials. Besides recycling typical household products and containers made from paper, plastic, glass and metal, it's also important to recycle things like cell phones, batteries and computers. In many places this "e-waste" can be taken to a recycling center for disposal in a way that will keep harmful chemicals from ending up in a local ecosystem.









    DRIVELESS


  • According to Washington University in St. Louis, another major source of ecosystem pollution comes from the harmful carbon emissions that every gasoline or diesel car and truck produces. With more stringent fuel economy standards coming to American cars, this problem is being addressed at the highest level. Hybrid and fully electric cars also help reduce emissions.
    However, every driver can participate by driving only when necessary and carpooling or using public transportation more. This puts less carbon into the air and, eventually, the ecosystem.

Buy Green Products

  • Buying green, or environmentally responsible, products is another way to prevent pollution. Green products are those that were made in an environmentally safe way and that can be recycled or disposed of with less impact to ecosystems. In products such as detergents and cleansers, chemical formulas are used that result in less harmful fumes, or in compounds that will dissolve in water or break down easily after a short time, making them harmless to the ecosystems they may enter.
    Green products may also use less packaging or help the maker support an environmental charity or clean-up effort. Research green products, and decide which ones do the most to prevent pollution.

Buy Less

  • Besides buying green, buying less is an excellent way to prevent pollution. Since every item in a store had to be produced, packaged and transported before going on sale, buying fewer products prevents harm to the environment on several levels.
    Buying reusable products, such as reusable grocery bags or cloth towels and napkins, can prevent the need to constantly purchase or use new products in the future. The website DoSomething.org is focused on promoting these sustainable practices.

kind of pollution

Water Pollution

W aterpollution occurs when a body of water is adversely affected due to the addition of large amounts of materials to the water. The sources of water pollution are categorized as being a point source or a non-source point of pollution. Point sources of pollution occur when the polluting substance is emitted directly into the waterway. A pipe spewing toxic chemicals directly into a river is an example. A non-point source occurs when there is runoff of pollutants into a waterway, for instance when fertilizer from a field is carried into a stream by surface runoff.  

Air pollution is the introduction of chemicalsparticulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or cause damage to the natural environment or built environment, into the atmosphere.
The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet EarthStratospheric ozone depletiondue to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems.
Noise pollution is excessive, displeasing human, animal or machine-created environmental noise that disrupts the activity or balance of human or animal life. The word noise comes from the Latin word nauseas, meaning seasickness.
Indoor air pollution and urban air quality are listed as two of the world's worst pollution problems in the 2008 Blacksmith Institute World's
The source of most outdoor noise worldwide is mainly construction and transportation systems, including motor vehicle noise, aircraft noiseand rail noise.[1][2] Poor urban planning may give rise to noise pollution, since side-by-side industrial and residential buildings can result in noise pollution in the residential area.
