Causes of Population Explosion in India
Human overpopulation or population overshoot is when there are too many people for the environment to sustain with food, drinkable water, breathable air, etc. In more scientific terms, there is overshoot when the ecological footprint of a human population in a geographical area exceeds that place's carrying capacity , damaging the environment faster than nature can repair it, potentially leading to an ecological and societal collapse. Overpopulation could apply to the population of a specific region, or to world population as a whole. Overpopulation can result from an increase in births , a decline in mortality rates , an increase in immigration , or an unsustainable biome and depletion of resources. It is possible for very sparsely populated areas to be overpopulated if the area has a meagre or non-existent capability to sustain life e. Advocates of population moderation cite issues like exceeding the Earth's carrying capacity , global warming , potential or imminent ecological collapse , impact on quality of life , and risk of mass starvation or even extinction as a basis to argue for population decline.

Overpopulation is a serious threat to our own existence. The whole world needs to address this issue and not just a few countries. Countries like Brazil, China and India add more to their woes by neglecting substantial increases in their populations. India is now the home to 1. Today India is stretched to its limit due to overpopulation.
Overpopulation occurs when a species ' population exceeds the carrying capacity of its ecological niche. It can result from an increase in births fertility rate , a decline in the mortality rate , an increase in immigration , or an unsustainable biome and depletion of resources. The change in number of individuals per unit area in a given locality is an important variable that has a significant impact on the entire ecosystem. In the wild, overpopulation often causes growth in the populations of predators. This has the effect of controlling the prey population and ensuring its evolution in favor of genetic characteristics that render it less vulnerable to predation and the predator may co-evolve , in response. In the absence of predators, species are bound by the resources they can find in their environment, but this does not necessarily control overpopulation, at least in the short term. An abundant supply of resources can produce a population boom followed by a population crash.
