Air pollution is a big problem in big cities. Evidence shows that air pollution may cause serious
health problems for humans and animals. We will get more health problems if we do not lower
the air pollution levels. There are some simple actions we can take to reduce air pollution.
First, get familiar with bus or train routes in your city and start to replace your motorbike travel
with a bus trip at least once a week. The frequent use of public transportation can help reduce
emissions that cause air pollution. You can even walk or bike for short distances.
Second, try to use less packaging. Factories can badly affect air quality when producing plastic,
foil and cardboard for packaging. Whatever you are shopping for, remember to choose items with
as little packaging as possible. If you have no choice, go for recyclable packaging.
Another good way to reduce air pollution is to manage your household waste. Reusing, recycling
and composting can help reduce a significant amount of garbage. That means that less garbage
will end up in landfills which are major sources of air pollution.
