Tehran has more than half of the country's basic industries such as electrical, textile, automotive, cement, chemicals and other industries, as well as many theaters, schools, universities, parks and museums.
The most important problems facing Tehran today are the suffocating traffic crises and high pollution in the atmosphere, resulting in respiratory problems for the Tehran's people.
