Smog in Big Cities

Smog in Big Cities

Population growth in big cities increases times two annually. In some years, more people will need transport, jobs on the industrial enterprises, and food that is grown with the aid of chemical fertilizer. The birth rate and health of the future inhabitants of metropolises depend on the urban environmental conditions. How can humanity prevent this massive disaster?


Smog is an air pollution and turbidity because of build-up harmful chemical compounds in the environment. The ways of addressing the problem of atmospheric pollution are simple. To prevent smog, it’s important to start with our own – to install the air purifying filters on the vehicles that do not let corrosive gases through, to abandon the conditioners of hybrid secretion, to use natural raw materials, and to exclude smoking.

Acid Rain

Acid Rain is a sediment with the increased acid concentration in atmosphere. The reasons for acid rains:

  • Volcanic eruptions.
  • The burning of coal.
  • Fires.
  • Weather changes.

It’s possible to track the level of environment damage if exploring the indicators of hydrogen (pH). The lower its level, the more chance the species will die.

Regional Ecological Problems and Their Possible Solution

Mines, paint and varnish factories, etc. should be located over the territory of the city, in the area where natural resources are poor. Workers on the plants should undergo medical examinations regularly, and they should be revitalized at the State’s expense.

Farmers, rural population often use fertilizers to accelerate growth of fruit and vegetables. Plenty of those substances contain ammonia – toxic volatile compound that escapes into the air. It’s necessary to implement natural fertilizers in agriculture that will enrich soil but not pollute ecosystem.
It not be forgotten that billions of lives depend on the ongoing generation. Before it’s not too late, one can stick car keys in a drawer, walk, give up smoking, take part in strikes and struggle for closing or changing the principles of enterprises.
