The world's population will balloon and almost double its current number of 7.2 billion come 2100, according to a study conducted by the United Nations.

Previous studies about the world's population claimed that people count will stabilize by 2050, but the new UN study suggested that there could be twice more people than we do today by the time we welcome a new century.

According to Discover magazine, the spur in population will be contributed largely by Africa, with a projection of 3.1 to 5.7 billion by 2100 from its current number of 1 billion.

While the increase in number was largely attributed to growth in Africa, Camilo Mora, a population expert suggested that it is a global problem and should not be put solely on the shoulders of Africa.

"We don't live on Planet Africa. We live on Planet Earth," Mora said in an interview with Healthline. "This is everyone's problem."

Mora also suggested that the repercussions of having a huge population can already be seen. "We don't really need to make any prediction because we can see it right now," he said. "We don't really need to look that far into the future to see the consequences of overpopulation."

The surge in number will reportedly pose problems in different areas including the environment, the adequacy of food and looming health problems.

"Rapid population growht can exacerbate the challenges that African countries will have in the future: poverty, environmental problems, health problems and resource depletion," said sociologist Adrian Raftery. "And in an increasingly globalized world, the problems in one part can impact the rest."

But while these are serious issues that need to be addressed in a larger scale, some say there is still hope.

"A rapidly growing population will bring challenges," said Raftery. "But I think these challenges can be met."

While the problems of the growth in the world's population appear to be worrisome, Raftery maintained that "there are challenges and we should be concerned, but I wouldn't subscribe to the idea that they can't be solved."
