    1. Effects of Overpopulation

    2. Outline Introduction: What is Overpopulation? Population Growth Current Effects Resources Economy Conclusion

    3. What is overpopulation? Overpopulation is a term that refers to a condition by which the population density enlarges to a limit that provokes the environmental deterioration, a remarkable decline in the quality of life, or a population collapse

    4. Population Growth 5.3 billion population of underdeveloped countries is expected to increase to 7.8 billion in 2050. The world's population is expected to rise by 40% to 9.1 billion. World population is currently growing by approximately 75 million people per year

    6. 1900 Africa - 133 million Asia - 946 million Europe - 408 million Latin America & Caribbean - 74 million Northern America - 82 million 2050 Africa - 1.9 billion Asia - 5.2 billion Europe - 664 million Latin America & Caribbean - 769 million Northern America - 445 million

    7. Current effects The rapid growth of human population has forced us to invade animal habitats , leading them to extinction. The speed of extinction of plants and animals attributable to human activities is 10,000 times faster than the natural quotient.

    9. continued Depletion of natural resources, especially fossil fuels. Famine Land shortage High prices in the housing market.

    11. Resources If current trends of human growth continue in Africa, the country will only be able to sustain 25% of its population by the year 2025. As population grows so will the fresh water shortage. Countries that dont have access to nuclear power wont be able to get their water by desalination.

    12. According to the California Department of Water Resources, if more supplies arent found by 2020, residents will face a shortfall nearly as great as the amount consumed today.

    13. Overpopulation and the economy Effects vary from place to place depending on the situations. Those who are unemployed because all of the jobs are filled up are a drag on the social services. People who do work and are consumers drive the economy.

    14. Conclusion As our numbers increase, there will be more conflicts at all levels, local, regional, national, international and global -- that wouldn't happen if population were stabilized.
