Air Pollution
Most of the air we breathe is not pure. It contains harmful substances called pollutants. These pollutants cause air pollution. Air pollution is causing lots of damage not only to us but also to animals and plants. More and more people are being affected by air pollution. The kids can't even play outside sometimes. They may suffer from asthma and other breathing problems.
Air pollution can be reduced by planting more trees. Trees use the carbon dioxide present in air for the process of photosynthesis. This way they help in decreasing the level of carbon di oxide in air. Trees also help in bringing rain which helps in cleansing the atmosphere. Factories are equipped with tall chimneys which carry smoke and waste gases high up into the air.
