Hi User!
Population is defined as the total number of human beings in a particular city, state, or country. We can calculate approximately the number of resources required by a particular area if we know the total population of that area. Population is a cause of concern for many countries as increasing population demands for more resources and our planet is falling short of natural resources gradually. India is the second most populated country in the world and is facing the resource crisis consequently.
There are various reasons behind population explosion and illiteracy is one of them. Majority of population in India is illiterate and weaker sections of the society tend to have more children as they don’t have knowledge about the birth control. Also, poor and illiterate class indulges in early marriage which ultimately results in more population as the young children are unaware of the facts related to reproduction.
The other main reason behind population growth is the decrease in mortality rate due to the advancement in science and technology. So all these factors contribute to population explosion and consequently exploit the environment and planet.
Population explosion is causing greater harm to the nature as increasing population necessitates urbanization and industrialization which ultimately leads to deforestation. Cutting down large number of trees destroys the natural habitats of various species which disturbs the ecological balance.
Pollution is another impact of growing population as people are purchasing more vehicles and polluting the air with harmful gases. Not only this, large number of industries pollute water bodies with the harmful chemicals, thus contributing to air and water pollution.
In addition to this, global warming and climate changes are some of the consequences of increasing population. Hence, it’s the need of an hour, that government should educate illiterate people about birth control measures and also take steps to encourage education in all classes of society so that this population rise can be stopped.
