Document Summary
Increase in population can lead to a depletion of resources a lot of current en: example as population increases the use and production of fossil fuel increases. Fossil fuels are taxing on the environment by increase use thus causing more environmental damage. Population growth rate is influenced by birth and immigration as positive factors. While death and emigration are a negative factor on population growth rate: population is the number of birth plus the number of people immigrating minus the death and the number of people emigrating. The population increases in time at an accelerated rate exponential growth: the idealize population growth when there is no competition for resources. Logistic growth pattern happens when the growth rate lowers as the population reaches its carrying capacity. Carrying capacity the maximum number of individuals in a population that the environment can support. Space, water, death, competition for resources, predation are limiting factors in population growth: it affect almost all species.
