Also how fast or slow the population increases over a specific period of time‚ and where the distribution is and why. Population of developing countries

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

After watching the programme‚ I realise that it is everybody ’s essential responsibility to confront and address the problems of an expanding world population.

Increasing importance has been placed upon population and population growth over the course of the past few centuries. Scientists are frenetically searching for the solution to this issue‚ and their outcomes are bleak.

ST The population of our planet will quickly reach a point where there will not be adequate amount of resources to support life on Earth. Population control must be enforced to avoid such a catastrophic occurrence. Many economic‚ social and environmental problems are either affiliated with or are increased due to overpopulation. With an exponentially increasing world population‚ the problems created by overpopulation grow correspondingly. In order to stabilize the massive population‚ the world
