As a result of these, pollution forms. A countermeasure technology has sprung up to combat the pollutions. All these technologies aim at reducing the waste material that is introduced in the environment by the human activities. Here are some technological methods that are used to control environmental pollution: 1. Reusing the waste matter: Recycling of waste products is a policy that has been encouraged by governments worldwide. Some of the materials recycled are like papers and polythene bags. Substances like polythene take long time to decompose. Reusing them would save additional waste to the environment that would make it unhealthy. Some items like iron when recycled are cheaper to process than going back to mining ore and processing it, and hence save money too. 2. Purification of dirty water: Dirty water is normally a health hazard. The process of purification is done by use of chemical elements like chlorine salt or mechanical methods. This technology is important since it helps to provide a solution to water shortage. It also helps to save life like in case of an oil spill in an ocean. Crude oil can cause damage and death of both marine flora and fauna. It hinders oxygen from dissolving in water that in turn may result to suffocation of the animals. The oil too clogs the feathers of birds making their predators to kill them easily. This kind of water pollution can result in an unbalanced environment. 3. Treating sewage: Sewage is the waste form of any material. Most of the sewage matter is absolutely poisonous. Some companies release their toxic waste matter to the water sources. This makes the water unsafe for consumption by both humans and marine life. However, there has been invention of technology that allows treatment of the sewage before it is released to water bodies. This technology is being enforced by various environmental agents. 4. Management of solid waste: This kind of waste is taken care of in several methods. It can be reused, treated or disposed properly such that it will not have any impact on the environment. 5. Using friendly renewable energy: Some of the fuels used like crude oil produce smoke that causes respiratory diseases, acid rain and other environmental pollutants. Use of solar energy that can be tapped by use of solar panels can reduce the destruction of the environment. Other sources of energy that technology has made trappable are water that produces hydro-electricity, wind, wood among others. 6. Use of clean energy: The scientists have put a lot of effort to discover some eco-friendly fuels that will help to curb all sorts of environmental pollution. This research has resulted in their unleashing discoveries like use of biogas that leave no waste matter. The car exhausts have been fitted with catalytic converters that reduce the toxic gases that reach the environment. All these efforts are supported by dedicated research in technology that would ensure pollution free environment.
