carrying capacity
Carrying Capacity
  • Means: The maximum number of people that an environment can support without negative or damaging effects
  • “Doomsayers like Paul Ehrlich and Garrett Hardin seem to think the Earth has already exceeded its carrying capacity while their critics such as Julian Simon seem to believe the carrying capacity of the planet is infinite”http://www.overpopulation.com/faq/natural_resources/carrying_capacity.html
Population Rates
  • Increasing greatly
  • Every minute of the day, 900 people are born
  • That makes about 1.3 million people a day
  • Today the World population is over 6.3 billion
  • The World Population is expected to double by the year 2050
death rates

  • Decreasing at a significant rate
  • Better medical treatment
  • Disease control (Malaria, Small pox)

  • Over population
  • We have the same amount of Earth and a lot more people to sustain
  • Famine – people dying of starvation
  • Stricter laws on child birth in some areas
