The population of Mexico is currently 92,000,000. In Mexico City in 1950, the population was 3,100,000. Now it is 15,600,000 - a growth of 12,500,000 in 50 years. Mexico's population has more than tripled since 1950. The population in the year 2020 is expected to be 130,645,000 if it increases at expected rates.
Overpopulation is a huge problem.
This overpopulation leads to the even greater problem of pollution. The pollution problem is so terrible that in a few decades chances are that Mexico will be uninhabitable. Car exhaust, factory emissions and residential gas tanks are harmful and lead to eye and respiratory problems, affecting the overall health of Mexicans dramatically. People in Mexico City usually have to drive with their headlights on at noon to see through the smog. Pollution is killing fish, a major source of income for individuals.
