In the article "How Many People is Too Many People" by Hannah Geis, the author is very concerned about too many people on our Planet and thinks of solutions to this threat. She explores the problems facing world population and how we can ensure that our resources do not dwindle as our population expands. Population growth is the increase in the number of people in a region and is occurring at all times all around the world. Population growth can have both positive and negative effects on countries, regions, and even the world.
