Human beings have lived on earth for tens of thousands of years, and during most of that
time their numbers were small. Before agriculture was developed about 10,000 years ago, the
death rate was high partly because of a limited food supply But after people began to grow
crops and raise animals for food, the death rate fell. And the population of the world slowly
grew.
The population of the world is not spread evenly over the earth. The average number of
people who live in an area or territory is called the population density. The most crowded
continents are Asia and Europe. Cities are more densely populated than rural areas.
Food and population cannot be separated. An adequate supply of food is one of the
human needs. Overcrowding has a bad effect on life.
A main cause of fanvine today is drought - a long period without rainfall. Crops wither
and die, and animals strave. Drought is almost impossible to control. In recent years, famine
has occurred in several african countries, including some in north eastern Africa.
