Breath easy! Air pollution
Air pollution happens when solid and liquid particles (called aerosols) and certain gases end up in our air.
These particles and gases can be bad for the planet and for our health
Many aerosols enter the atmosphere when we burn fossil fuels like coal and petrol, and wood. These particles can come from many sources, including car exhaust, factories and even wildfires.
We can reduce air pollution by using more fuel efficient things in our house (like fridges and televisions) and driving electric cars that aren't powered by fossil fuels.
