Air pollution is the main cause of global environmental threat. The air is polluted by any substances: gaseous, solid and liquid. Air pollution is the most dangerous of all types of pollution.

The main sources of air pollution are industrialization and a growing population, the energy industry, the transport industry, and natural sources.

One way to solve this problem is to save on electricity and fuel to help reduce air pollution. This movement will reduce the use of electricity and fuel, which will reduce the amount of air emitted and reduce air pollution. Power plants need fuel to generate electricity to improve people’s lives. Reducing the corresponding power consumption will help reduce the number of discharges in electrical factories. It is important to note that people can start with simple things to help reduce their energy use. They can turn off the lights and reduce air usage. Thus, saving electricity is an effective way to reduce air pollution.

Another effective way to help the environment is to grow more trees. Trees are capable of producing oxygen, a substance that contributes to air pollution. In addition, carbon dioxide, the most important source of global warming, can be taken up and then converted into oxygen by trees.

Also, using public transport instead of driving a car can reduce air pollution. People are increasing the use of bicycles and the subway, which reduces the number of empty cars, which reduces air pollution. Bicycles do not emit exhaust gases, which is beneficial for the air environment. Also, by riding a bike or walking instead of driving, you can do excise taxes, which are good for people’s health. On the contrary, the use of public transport can improve the air environment.

The graph shows the amount of money spent on different modes of transportation in one of the countries from 2016 to 2020.

              As we can see from the graph, the most money was spent on privately owned cars in 2018. The least money was spent on trains in 2016. We see a gradual increase in the amount of money to use trains from 2016 to 2018. Then from 2019 there is a slight decline.

In terms of the use of air transport, we see a sharp increase in the amount of money used from 2016 to 2018. In 2019, the use of money for privately owned cars, air transport and trains was the same.

We can make conclusion that privately owned cars remain the most attractive mode of transport among those listed. The role of trains first increased, and then decreased. Air transport is less popular than privately owned cars.
