Air pollution

      A significant portion of industry and transportation burns fossil fuels, such as gasoline. When these fuels burn, chemicals and particulate matter are released into the atmosphere. Although a vast number of substances contribute to air pollution, the most common air pollutants contain carbon, sulfur, and nitrogen. These chemicals interact with one another and with ultraviolet radiation in sunlight in dangerous ways. Smog, usually found in urban areas with large numbers of automobiles, forms when nitrogen oxides react with hydrocarbons in the air to produce aldehydes and ketones. Smog can cause serious health problems.

         Acid rain forms when sulfur dioxide and nitrous oxide transform into sulfuric acid and nitric acid in the atmosphere and come back to Earth in precipitation. Acid rain has made numerous lakes so acidic that they no longer support fish populations. Acid rain is also responsible for the decline of many forest ecosystems worldwide, including Germany’s Black Forest and forests throughout the eastern United States.

Water pollution

           Estimates suggest that nearly 1.5 billion people worldwide lack safe drinking water and that at least 5  million  deaths  per  year  can be attributed to waterborne diseases. Water pollution may come from point sources or  nonpoint  sources. Point  sources  discharge  pollutants from specific  locations,  such as factories, sewage treatment plants, and oil tankers. The technology  exists to monitor and   regulate  point  sources  of pollution,  although  in  some areas this occurs only sporadically. Pollution from nonpoint sources occurs when rainfall or snowmelt moves over and through the ground. As the runoff  moves, it picks up and carries away pollutants, such as pesticides and fertilizers, depositing  the  pollutants  into  lakes,  rivers,  wetlands, coastal  waters,  and even underground sources of drinking water. Pollution arising from nonpoint sources accounts for a majority of the contaminants in streams and lakes.

With almost 80 percent of the  planet  covered by oceans, people have long acted as  if  those  bodies  of water could serve as a limitless dumping ground  for  wastes. However,  raw sewage,  garbage,  and oil spills have begun to overwhelm the diluting capabilities of  the  oceans, and most coastal waters are now polluted,  threatening  marine wildlife. Beaches around the world close regularly, often because the surrounding waters contain high levels of bacteria from sewage disposal.

Simple 5 things which you can do to stop global warming

          1. Reduce, Reuse, Recycle

          2. Use Less Heat and Air Conditioning

          3. Change incandescent bulbs to CFLs bulbs

          4. Turning off lights when you leave a room,office and etc.

          5. Plant Trees :- plants absorb carbon dioxide and give off oxygen.
