Some people think international car-free days are an effective way of reducing air pollution; however, others think there are some other ways. Discuss both views and give your opinion

While

international car-free days are thought to effectively reduce the level of

air

pollution, some other people believe there are alternatives that are

also

effective. I will discuss both of these views in my essay below. On the one hand, it is true that exhaust fumes from cars are majorly responsible for polluting the

air

as they contain a relatively high proportion of pollutants

such

as CO2. By having some days without cars on the road, no harmful smoke will be released into the atmosphere, and

this

will

therefore

improve

air

quality.

This

policy is extremely effective in big cities around the world. Take Beijing, the city known for its dirty

air

and its atmosphere covered with smog,

for example

. Since

this

car-free policy was strictly operated, the

air

quality of the city has greatly improved.

On the other hand

, local governments should encourage the use of public transport like subways because it produces a smaller quantity of pollutants and is less likely to damage the

air

.

Also

, the disposal of waste, especially plastic waste that emits toxic fumes if burned carelessly, at landfills should be closely monitored. The final and most effective way is to use sustainable and environmentally energy sources.

For example

, solar or wind power, to replace fossil fuels in the long term. In my view, those measures are all effective in addressing the problem of

air

pollution, but only to a certain extent.

Such

a problem needs to be dealt with by different approaches and I always feel that if there is only one way being implemented, it will not be enough.
