The term human population simply would be the number of people thriving in a specific area which could range from a village to the world usually. Additionally, the term is used to describe the inhabitants also but in most cases, the term would mean numbers.
Despite most of us being aware of the population of humans during ancient times, it is presumed that there might have been around tens of thousands of Homo sapiens (scientific name of humans) when they appeared on this planet before 200000 years. Presently, around 6 million of them reside on this planet. In the Asian continent itself, around three-fifths of the world population resides except Antarctica and the rest of them resides in other continents.
The present population explosion had its origin from the time of the industrial revolution and the half of the present population happened since 1950. The majority of the world populations are coming from the developing countries. The immigration levels in Europe and Japan has reduced the population considerably. However, the immigration of larger families at higher levels has contributed to the growth of population in developed countries like Australia, Canada, and United States.
Owing to the advancement in healthcare and allied services, the birth rates have climbed significantly and surpassed birth rates considerably resulting in the current population explosion. For the growth of world population, another reason that could be attributed to would be in the form of women delivering more children than the earlier generations. The rise in population has contributed to concerns among biologists around the world that whether the earth’s support systems would be able to bear the burden of the same.
As per the arguments of renowned biologists around the world, the rise of the population around the planet has a detrimental impact on forests, cropland, freshwater, fisheries and so on at a larger scale. Another group of social scientists and economists, on the contrary, argue that the hike in population would turn as an asset in the form of human resources and create wealth. But from our observation, it has more negative impacts than positive ones on the community and ecosystem
Thus, it could be concluded that human population has its own merits and demerits as such depending upon the perspective of the persons assessing the same.
