Environment of Pakistan
This article discusses topics related to the environment of Pakistan
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution.
Pakistan's coastline, which stretches over 1,046 km, is facing severe pollution due to a combination of industrial, port, municipal, and transportation activities in the area. The coastline is being overwhelmed with water-borne pollution being discharged in the shipping process into the marine environment. A recent study found that some of the marine life was contaminated with lead, which if consumed by humans through seafood, has been linked to anemia, kidney failure and brain damage. In fact, the study also discovered that even the mangrove forests protecting the feeder creeks from sea erosion as well as a source of sustenance for fishermen are threatened by this pollution.
The Air pollution is the release of chemicals and particulates into the atmosphere. Common gaseous pollutants include carbon monoxide, sulfur dioxide, chlorofluorocarbons (CFCs) and nitrogen oxides produced by industry and motor vehicles. Photochemical ozone and smog are created as nitrogen oxides and hydrocarbons react to sunlight. Particulate matter, or fine dust is characterized by their micrometre size PM10 to PM2.5. The air in Karachi is rapidly polluted by automobile smoke, especially Rickshaws and Buses, industrial emissions, open burning of garbage, house fires, and other particles but the government and environment organizations seems non-serious to tackle the issue timely.
