The air we breathe

Air is a mixture of many gases. When we breathe in air, we take in oxygen and give out carbon dioxide. Without oxygen, we would most surely die. Air is essential for both plants and animals.

Poisonous gases are emitted in to the air by factories and vehicles. The air is filled with poisonous gases and if this continues very soon we may not have any pure air to breathe.

People suffering from asthma have difficulty breathing polluted air. Air pollution has resulted in many children developing respiratory problems. Many countries are facing the phenomenon of acid rain which is caused by the human emissions of sulfur and nitrogen compounds which react in the air.

If more people would use public transport, there would be lesser emission of pollutants into the air. Use of vehicles that run on electricity would contribute significantly to the control of air pollution.
