Population Explosion:
The quick and dramatic increase in world population has occurred over the last few hundred years. The world’s population rose from 1.65 billion in the year 1900 to 3.02 billion in the year 1960 and reached 6.1 billion in 2000. Therefore the size of the population almost quadrupled in the span of 100 years, a historically unprecedented rate of raise. This sudden raise in population is termed as Population Explosion or Population Trap or Population Bomb.Reasons for the Explosion:
The most important reason for slow and fluctuating population growth previous to early 1800’s was the occurrence of diseases like diphtheria, small pox, measles and scarlet fever. Additionally, epidemics of diseases like cholera, typhoid fever, and plague removed large number of adults. Famines also were not abnormal. Biologically speaking, previous to 1800’s the population was fundamentally in a dynamic balance with natural enemies and other aspects of ecological resistance. High reproductive rates were mostly balanced by high mortality.As in the 19th century:• Discoveries of vaccination give protections to most of the infectious agents• Discovery of antibiotics is a main breakthrough in the medical history,• Enhancements in agricultural methods,• Enhancements in the nutrition and• Better sanitation and individual hygieneBrought about impressive reductions in mortality, particularly among infants and children. The birth rate has remained very high. Therefore the human population entered into exponential growth, as they were free from natural enemies and other ecological restraints.
