Today, humans almost inhabit every continent on the planet, though there are no major human settlements in Antarctica and North pole, a minor number of people live there as well. “Homo Sapiens” or the Modern Human, is the first species since the beginning of life on Earth to colonize the entire planet geographically, and the population is ever more increasing.
Global Population reached 1 billion in 1800 AD, and it took 200,000 years to that.

Worldometers estimated that the world population will grow to 8.5 billion in 2030 and to 9.7 billion in 2050.

Aftermath Of Increased Population And The Effect Of Over-Population
Although the global population has decreased to less than 2% per year, the overall population is growing and at present, it has posed major issues in areas such as,
- The growing population will certainly face resource scarcity problems in the future, especially in energy and food supplies.
- Environmental Impacts: as the population grows, more land is required for them to settle and more industrialization is required to meet their demands. Urbanization and industrialization eventually lead to deforestation and through that loss of biodiversity, increase in green-gas emission and much more environmental cataclysms.
- Loss of Standard of Living: as the population upsurge, so will be the costs of welfare, maintenance, upkeep, security, government infrastructure investments, and many more related costs. This burden will eventually fall upon the citizens of the same nation and as an indirect result, the standard of living of households will decrease.
Some estimates suggest that around 110 Billion has lived on Earth since the dawn of modern humans.
