Why is population such a major issue of concern for Earth systems?

rovide a brief discussion of how increasing population will impact societies and economics. Discuss what the future of human population may look like? Assuming future predictions of population growth are correct (See UN report p.1-3) do you think that all countries/continents will be affected equally by population growth or decline? If not discuss briefly how the impact will vary and why?
