What Causes Acid Rain?





Even without air pollution, the carbon monoxide occuring naturally in the air makes rain slightly acidic. But in recent years, air pollution has increased the acidity of rain and snow to the point where precipitation has turned into a deadly threat to

numerous organisms ranging from fish to forests.


When cars and factories burn fossil fuels, they release into the atmosphere pollutants such as sulphur and nitrogen oxides, halogen compound and a variety of hydrocarbons. These pollutants react with the moisture in the air to form highly acidic substances such as sulphuric acid, nitric acid and hydrochloric acid. Raindrops and snowflakes then deliver these acids to rivers, lakes and forests, making the soil and water inhospitable to life.

First, particles of sand, mud and grit sink and settle in a tank and then the water passes to filter beds where any remaining dirt and some of the bacteria are

Sea Pollution- A Threat to Marine Life

Image
The sea is polluted in different ways. Sometimes, things are dumped or split right into it. Waste and chemicals are also washed into it from homes, factories and farms. The water people use in their homes gets dirty. Sewers carry much of this waste water away. Many factories get rid of their waste in a similar way. Most of this waste water ends up in rivers, lakes and oceans. If it is not cleaned first, it can pollute the water. Fertilizers and other agricultural chemicals are sprayed on crops. When they are washed into rivers by rain, they reach the sea and pollute it. Offshore oil rigs pump up oil from beneath the seabed. Sometimes, oil leaks into the ocean from these operations and pollutes the sea. Oil tankers are another cause of water pollution . If one of these ships has an accident, it can crack open and split oil into the water. How we can help? Our  modern need for
