World Population Day

According to the United Nations July 11 in 1987 the world population was about 5 billion people — that day was provisionally identified five billion Day (Five Billion Day). Two years later, in 1989, the UN established the International Festival — World Population Day (World Population Day), which is celebrated annually on July 11.

The rapid growth of the world population was in the 60's of significant concern of United Nations. The world's population from 1960 to 1999 more than doubled, going to the October 1999 level of 6 billions.

Although the growth rate began to decline — from 2 percent to 1.3 percent between 1969 and 1999 — an absolute increase is now almost 77 million people a year, with 95 percent of that increase was the share of developing countries.

In the 20th anniversary of the Day of the five billion — 11 July 2007 — the world's population was about 6.7 billion people.

According to the United Nations in 2050 the world will be living from 7.9 to 10.9 million people, and most likely 9.3 billion, which depends to some extent on the effectiveness of family planning programs.

Extensive and intensive UN work in the field of population, especially its authoritative assessments and forecasts of population size and dynamics of change, served as a substantial strengthening of the national base of long-term planning that can incorporate demographic statistics in the context of development planning and to make informed decisions in the socio-economic field.

In the 21st century has become particularly acute considered the issue of global warming on Earth, caused by the general increase in population and the extensive human activity. Last often has a negative impact on terrestrial resources and the environment, leading to irreversible consequences.
