this problem but the common factor is the human race. The human race has to put controls in place and take care of the environment‚ so the required resources do not become extinct. What causes Overpopulation?

Right now there is estimated to be 6.765 billion people in the world. Based on several causes of overpopulation this

Discuss the ways in which distinctive ecologies can develop along routeways (10 marks) Routeways such as roads‚ railways and canals can provide habitats for many species of plant and insect life because they often act as protected areas in which ecological succession can occur. There are several ways in which this can happen. One way in which ecologies can develop along routeways is that plant seeds‚ e.g. Oxford ragwort or buddleia‚ that have become windborne can be transported along by cars or trains

POPULATION GROWTH AND ENVIRONMENTAL DEGRADATION IN INDIA Introduction The rapid population growth and economic development in country are degrading the environment through the uncontrolled growth of urbanization and industrialization‚ expansion and intensification of agriculture‚ and the destruction of natural habitats. One of the major causes of environmental degradation in India could be attributed to rapid growth of population‚ which is adversely affecting the natural resources and environment

The word “Population Growth” has its origin from the latin words ‘Populus’ meaning people. According to ecological term; “population is group of people of the same species occupying a particular space”. Population is subdivided further into demes or local population which is group of interbreeding organism in demes; they share a common gene pool. Population density is defined as a number of individual per unit area or per unit volume of environment. When the size of the individual is uniform the

Population should be controlled for a number of reasons. Firstly‚ the resources are limited and are running out. Secondly‚ shortage of finances is a result. However‚ it is considered an unethical practice in some religions and abortion is strictly prohibited. Moreoever‚ it adds to the GDP as more is demanded consumed and produced. Beginning on this topic‚ first and foremost reason as to why population should be controlled is because natural resources are running out. Not everybody has access

common models of population growth is the exponential model. These models use functions of the torm p(t) : po€rt‚ wherep6 is the initial population and r > 0 is the rate constant. Because exponential models describe unbounded growth‚ they are unrealistic over long periods of time. Due to shortages of space and resources‚ all populations must eventually have decreasing grovtrth rates. Logistic growth models allow for exponential growth when the population is small. However‚ as the population approaches
