Earth population to reach 7 billions in three years

The Earth population will reach 7 billion people by 2012 and there will be about 9 billion people living on our plant in 2050.
According to a UN forecast, population growth will continue being observed in Asian and African countries including India, Pakistan, Nigeria, Ethiopia, Tanzania, China and Bangladesh.

The population of the USA is expected to reach 403 million people in 2050 (it is 314 millions now). The growth will be possible because of a great increase in the birth rate and immigrants. About a million people will arrive in this country every year, reports ITAR-TASS.
