Why High Birth rates?

Population explosion

From 1750 to the present day the world's population has been constantly increasing. In 1750 the population was less than 1 billion, then it was slowly increasing to 1.2 billion in 1850 and 2.7 an 1950. From 1950 to 2012 the population started to rise at a faster rate. By 1975 it reached about 4 billion and 2000 about 6 billion. This is called population explosion.

Population growth takes place when birth rates are higher than death rates (natural increase). In most continents of the world this is what is happening. The fastest rates of growth are actually happening in the poorest continents like Africa, Asia and South America. However, in Europe death rates are actually higher than birth rates so natural decrease is taking place.
