What is population in biology?

Population is defined as the total individuals of a species in a given geographical area. While populations of a species acquire different areas are called sister populations in a geographical area, the population is further divisible into subgroups called demes. The population present in an area are capable of interbreeding among themselves. The chances of interbreeding are more between individuals of same deme than between different demes of that population which is further reduced between populations of sister populations. An individual usually interact with their closest neighbors, but if at some other point in the life cycle widespread movements occurs such as a dispersal stage, the deme is much larger than such neighbor interactions. The description of a population requires three parameters numbers and kinds of the species in an area or space and time. On Earth, various biotic interaction and effect of abiotic factors population can be dispersed:

Why does the biotic community disperse?

This dispersal of biotic community also occurs on the basis of availability of food and abiotic parts of environment interact with the biotic community. Habit of food and interaction between food chain also helps the population to survive in any area which is termed as food web; the individuals get more options of food than traditional way in its habitat.

Why do cities grow?

In past few years, cities grow due to the rapid increase in world population and the migration of people from villages to cities. In the developing countries, the population growth has been more unstable& some cities are facing unplanned and uncontrolled settlements (e.g. slums) at the densely populated areas. Human beings have maximum population on earth although it decreases with high death rate due to illnesses, infections, famines; accidents and war but comparatively fertility rates should be high for species survival. Many factors affect the rate of change of population. As number of individual increases, the problems related to it are also increased. The main reasons that affect growth of population are the natality, mortality, immigration and migration. The natality is the ratio between births and individuals in given population and time. The mortality is the ratio of number of deaths to individuals present in given area and time. Migration is the number of people enters in or out of an area. The rate of change of population size is affected by these factors in a particular region. Overpopulation has been initiated due to the increase in birth rates and the decrease in death rates in present time due to better medical facilities and progresses in the field of medicine. Movement of people to developed countries for better job opportunities, war, and natural disasters like hurricanes, cyclones, earthquakes etc. There is great pressure on the natural resources (water, land) due to overpopulation. Among all the natural resources, Land is the most important one. All agriculture, animal and forestry productions depend on the land productivity. The entire land ecosystem, which composed of soil, water and plant, and soil biodiversity, is used to fulfil the community demand for food, energy, water requirement. The unmanageable use of land is the main reason for destruction of our environment. For the sustainable development of an area, regular monitoring of land cover/ land use changes is essential. Overpopulation, consumption, overuse, wastage and misuse of resources have strained the earth’s carrying capacity. The demands that put pressure on our environment are also alter the future of sustainability on earth. Regular monitoring of urban land cover/ land use changes is necessary for sustainable development of an area. In India, increase in population size due to unplanned activities which leads to urbanization that reduces the agricultural land. This is also having serious impacts on the resources base of the region. The development of urban area takes place either in radial way nearby a developed city or linearly along the highways. Life of Indians depends on agriculture and similar activities in rural areas. As per Indian census during 2011, the population of country is 1,210,193,422 (Provisional Census, 2011). The Indian populations increased with a decadal growth of 17.64%. In this chapter, the impacts of increased population on land use types and availability of land for agriculture, industry, construction of dams, water bodies etc. and in turn their impact on environment will be discussed.

How has human overpopulation affected the ecosystem?

Human overpopulation is a major driving force behind the loss of ecosystems , such as rainforests, coral reefs, wetlands and Arctic ice. Rainforests once covered 14% of the Earth’s land surface, now they cover a bare 6% and experts estimate that the last remaining rainforests could be consumed in less than 40 years and certainly by the end of the century at the current rate of deforestation. Due mainly to warming temperatures, acidifying oceans and pollution, close to 30% of the ocean’s reefs have already vanished since 1980, including half of the reefs in the Caribbean and 90% of the Philippines’ coral reefs , and scientists forecast that Australia’s Great Barrier Reef may be dead by the year 2050 and all coral reefs could be gone by the end of the century. Furthermore, the area of permanent ice cover is now declining at a rate of 11.5% per decade, relative to the 1979 to 2000 average. If this trend continues, summers in the Arctic could become ice-free in as few as 4 years or in the next 30 years. Wetlands are increasingly under threat in the United States, but also all over the world. In the U.S., less than half of original wetlands remain with 53% being lost, which is about 104 million acres. In Europe, between 60% and 70% of wetlands have been completely destroyed.
