Key questions
Air quality tells us how healthy the air is to breathe. If the air quality is bad then it has more harmful things in it. Good air quality tells us that there is less pollution and it is better for us to breathe.
The air that we breathe is made up many different gases. Some of which are natural and essential for life. Air pollutants can be released from natural sources such as volcanoes, but humans are responsible for a large proportion of the pollution in our air today.
A lot of things that make our lives more comfortable such as cars, electricity and heating create pollutants but make the air dirty. Sometimes we cannot see air pollution but other times it can be seen in the form of smoke or dirt.
The release of air pollutants must be kept to a minimum, as some of the pollutants can be harmful, not only to us humans but to wildlife and our environment.
If you are sensitive to air pollution you might start to cough or find it difficult or painful to breathe when air pollution is high, especially if you are running around outside or playing sport. Some people might not be affected at all.
We could all help to reduce pollution from vehicles by using our cars less. Instead of using a car for short trips to school or to the shops, try to walk or ride a bike.By changing our behaviour and following the advice below, we can all make a positive impact on air quality.
