There would no longer be empty land often found in underdeveloped countries and low resource areas. People would be forced to relocate out of big cities like New York City, Tokyo, Mexico City, and Seoul.
The overpopulation would result in poverty, sickness, and overcrowding. Poverty would occur because there would not be enough jobs to provide pay for everyone. Sickness would spread around everywhere because people are too close to each other, and most would not have proper health medication. This can be predicted by the population of Africa. Africa is extremely overpopulated. The crowdedness and limited space are all contributing factors to the high percentage of children and adults with fatal sicknesses.
The future for our world would not look very good. The population would continue to grow, only to soon have an extremely rapid decline because the earth has reached its carrying capacity. The people would also have to find a new place to live. Because the cities would be overcrowded, people would have to use areas that are not the most desirable. Such as extremely cold and icy areas like the Arctic Circle.
This video shows how much the earth has grown since 1 A.D. up until the current year.
