A population is all the organisms that both belong to the same group or species and live in the same geographical area . In ecology the population of a certain species in a certain area is estimated using the Lincoln Index . The area that is used to define a sexual population is such that inter-breeding is possible between any pair within the area and more probable than cross-breeding with individuals from other areas. Normally breeding is substantially more common within the area than across the border. [ 1 ] In sociology , population refers to a collection of human beings.
WOA!! World Ovepopulation Awareness
Population is not of concern if there are enough resources to go around. Important resources like water of suitable quality for growing crops, drinking, cooking, and cleanliness, fertile soil for growing food and trees, and fuel for warmth and cooking. Depletion of important resources leads to poverty, disease, malnutrion and often death. Impoverished people are usually forced to destroy their environment in order to survive.Albert Allen Bartlett (born 1923 in Shanghai ) [ 1 ] is an emeritus Professor of Physics at the University of Colorado at Boulder , USA. As of July 2001 [update] Professor Bartlett had lectured over 1,600 times since September, 1969 on Arithmetic, Population, and Energy . [ 2 ] [ 3 ] Bartlett regards the word combination " sustainable growth " as an oxymoron , since even modest annual percentage population increases will inevitably equate to huge exponential growth over sustained periods of time. He therefore regards human overpopulation as "The Greatest Challenge" facing humanity. [ edit ] Career Bartlett joined the faculty of the University of Colorado in Boulder in September 1950.
