Urban centers are filled with motorized transport and other sources of pollutants like waste from the large populations of people, or emissions from factories. The urban centers have very few or even totally missing green spaces with higher amount of pollutants that are so harmful for citizens. For a long time, lung cancers, chronic obstructive pulmonary diseases and asthma are just a few diseases common among urban dwellers.

We are living in the life of technology and the Internet. Despite some good affairs, it seems to me that modern lifestyle changed in a negative way.

One the one hand, a majority of people consider that technology is the vigorous factor in modern lifestyle. It provides easier and faster life. Furthermore, because of the well-developed technology, people gain more advantages in life.

On the other hand, this modern life has some disadvantages. One of the most complained problems is loneliness. Besides, people become more dependent on new technology. Even if the calculator is a good invention, man no longer makes mental calculation and no longer works his memory.

In conclusion, in spite of the fact that modern lifestyle gave us some barely adequate opportunities, there are much more disadvantages comparing within the past.
