Human Population Growth and the Environment
This paper describes the human population growth and its implications on the environment. It explains the trends of the world human population since its origin, the limit concept known as carrying capacity and the effect of rampant continued growth from the carrying capacity. It is floodlit at how the size of the population contributes to environment degradation, and why the population size counts when attempting environmental restoration projects.
Human population is the total of the number of people whose habitation is the earth. The world human population constrains the balance of the factors of population increase and those of population decrease. These factors are birth, death, emigration and immigration. Birth and immigration constitute the population increasing factors while death and emigration constitute the decreasing factors. The study of the population, its density, size, and behavior refer to as demography. The historical trend in human population theoretically describes majorly in phases based on the influencing factors for each phase. The most traceable eras are the early agricultural revolution, Christian era and industrial revolution. This era of agricultural enumeration came with improved agricultural tools and modern methods of cultivation that combined maximization of land and labor for output, thus consequently increasing the population due to food security and the desperate need for labor.
The Christian era traces eight thousand years later after the agricultural revolution. The earth’s population had risen up to three hundred million. This acute growth, however, became fitful and slow, due to the plague epidemics and other catastrophes of the middle ages. By the year 1750, which is arguably the beginning of the industrial revolution mushroomed in Britain, the world population had a staggering over eight hundred million. Population projection is a scientific technology that involves the use of fertility rates, mortality rates and trends in migration to predict the human population over a given timeline.
The changes and trends in human population over time has had impacts and conversely impacted on by changes in technology, the growth of the field of medicine, the diversification of cultural space and nutritional approaches and methods. Population and general demographic sets of data used in models described to relate to technological dates, justifications and also future projections. Differed models of reason have developed based on their approach schemes. Approach in terms of technological advancement based on labor intensive resources views weighing changes in human population as a cause for technological advancement. Other opposing models, which explain technological advancement in terms of land or space, find population increment as a barrier to technological advancement. The world human population trends have tremendous
