more and more contaminated and

also

will propose some solutions to handle the problems of

air

contamination in big

cities

. One of the important causes of

air

pollution is the significant increase of private traffic transportation means in big

cities

,

such

as motorbikes, cars, that dispose of a large amount of carbon dioxide and other poisonous gases affecting directly to the

atmosphere

, resulting in

air

contamination. Another factor

that is

determined widely is the development of construction activities. These construction activities could generate a huge amount of dusks at a low

atmosphere

level that affects directly the living environment of people.

This

problem has become more popular in big

cities

of developing countries in which demands on building infrastructure systems and high buildings are increasing dramatically in recent years

In addition

, the number of people living in big

cities

has become more crowded for their living and working demands, resulting in discharging wastes and rubbish that could produce greenhouse gases into the

air

. In order to solve these problems caused by the factors mentioned above, there are some following beneficial solutions.

Firstly

, the government should have specific strategies to reduce private transportation types

such

as motorbikes, cars by developing public vehicles and using green energy sources to replace fossil energy sources in order to reduce greenhouse gas emissions.

Secondly

, the construction activities in central places should be limited to reduce the discharge of dusks into the

atmosphere

. In conclusion,

air

pollution is still a currently serious problem in many big

cities

throughout the world and

this

problem is caused by different factors but most of the causes for

this

are from people.
