Review of related Literature As can be seen in Figure 1‚ the world’s population grew very slowly until about 1750. There was a long period of stationary growth (no growth) until 1000 B.C.E.‚ when the world’s population was approximately 300 million; this was followed by a period of slow growth from 1000 B.C.E. to approximately 1750‚ at which time global population was an estimated 800 million. Until this time‚ the world’s population was kept in check by high death rates‚ which were due to the combined

Abstract The population dynamics of Daphnia magna are observed under three different conditions; low‚ medium‚ and high density. The effects of different population densities on the survivorship and reproduction of Daphnia are observed over a two-week period within a lab environment. Over the two week period‚ the numbers of parent Daphnia alive and dead are recorded daily‚ along with the amount of offspring produced each day. From the main parameter investigated‚ the net reproductive rate‚ the

1.Introduction Population growth is one of the major environmental issues today. Some people argue‚ that rapidly growing population is not only problem and humans will not destroy life-support system on which we all depend.

Should Government Attempt to Control Human Population Growth? Human population grows‚ and it has been calculated that by the year 2050 there will be over 9 billion people in the world. As a result of that the amount of land per person will have dropped to less than one square inch. It is clear that population growth must stop in some close future due to various factors (Issitt‚ 1). Shortage in food and water‚ limited energy‚ pollution‚ death of plants and animals‚ and many more other shortages
