  • The population growth rate measures how populations change in size over time. The units of population growth rate are individuals per time. Population size can only be changed by four factors. Births add new individuals to a population whereas deaths remove individuals from a population
  • World Population=7,432,663,275 United States Population=322,762,018
  • Developing Countries: Afghanistan=2.78% Albania=0.27% Developed Countries:Sweden=0.16% Germany=-0.21%
  • Human population growth impacts the environment because as the population increases more people need resources and more waste is produced. Since so many people are sharing a limited number of resources it strains the environment. Also with the growth of population more and more land needs to be cleared in order to build things that are needed for human survival examples are houses, factories, farms.
  • Human population growth impacts the survival of other species because some species are being killed for sport or food and is lowering the population of the specie. human population growth also impacts species because many animal ecosystems are destroyed and the species are forced to relocated and their numbers decrease over the years.
  • China has addressed the problem by having a one-child policy which only always the birth of one child in a Chinese family. India operates a two child policy allowing two children per family. France offers financial incentives for larger (3 child) families.
