Transcript

  • 1. Water Resources in the U.S.
    Anoud Al Thani
  • 2. Social Implications
    Due to population increase in the U.S., there is a greater demand for water so there is a greater strain on the resources present
    Americans make up 5% of the world’s population but consume 24% of the world’s water
    While U.S. per capita water use has declined, it is offset by the increase in population
  • 3. Economical Implications
    States in the U.S. like California that consume a great deal of water do not have water resources to supply the people so they have to purchase water from other states putting a burden on that state’s economy
    America’s breadbasket relies heavily on the Ogallala aquifer which is rapidly being depleted
    Many water resources in the U.S. are shared between many States – who do they really belong to, who is responsible for maintaining them, etc.
  • 4. Political Implications
    The Colorado river eventually empties into Mexico. The U.S. has to maintain strong political ties with Mexico since there have been an increase in dams along the river for hydroelectric power as well used for human consumption.
    Because the competition for limited water resources is becoming greater and greater, States in the U.S. fight over water, make it a part of the political platform, and it could lead to civil unrest
  • 5. Environmental Implications
    Groundwater is being depleted faster than it is being recharged
    Droughts are becoming more severe leading to shortage of usable farmland for plants and livestock
    Pictures of the impact of droughts are shown on the next slide as well as areas in the U.S. that are most at risk for droughts
  • 6. Environmental Implications
  • 7. Environmental Implications
    When groundwater gets depleted, salt water replaces the fresh water so coastal area farming is becoming more and more difficult as plants can’t tolerate salty water
    Areas in the U.S. where population is growing at a high rate have the most negative impact on the environment – Las Vegas, Nevada was built in the desert with limited water resources – they have to get water from other states
  • 8. Potential Solutions
    Water saving sprinklers on farms that reduce rate of evaporation
    Water saving toilets
    Xeri-scaped lawns – remove grass and plant things that require very little water – each plant is watered individually
    Water saving shower-heads
    Take shorter showers, not baths
    Grey water used to water plants
    Give tax incentives for conserving water and lowering personal consumption
  • 9. Pictures of Potential Solutions
  • 10. Bibliography
