Resources and Human Impacts on Earth Systems

  1. 1. Resources and Human Impacts On Earth Systems <br />
  2. 2. Renewable Resources<br />Any resource that can be replenished naturally over time. <br />Examples:<br />Wood energy<br />Solar energy<br />Wind energy<br />Water <br />
  3. 3. Nonrenewable Resources<br />Any resource that can’t be recreated on a scale compared to its consumption. <br />Made by nature<br />Examples:<br />Oil<br />Coal<br />Natural gas<br />
  4. 4. Benefits…<br />Renewable Resources<br />Nonrenewable Resources<br />Less Pollution<br />Naturally replenished<br />Environmentally friendlier <br />Avoid depletion for future<br />Necessary for life <br />Provides better energy than renewable resources<br />More functional<br />
  5. 5. Costs…<br />Renewable Resources<br />Nonrenewable Resources<br />Not practical<br />Hard to maintain<br />Expensive<br />overused<br />Will eventually run out<br />Can’t be remade<br />Can’t be replenished<br />Takes millions of years to be made <br />
  6. 6. Impact Of Humans On the Environment<br />Deforestation<br />Pollution<br />Coral reef destruction<br />Erosion<br />Invasive species<br />And many more!<br />
  7. 7. Deforestation<br />Cutting down and/or burning of Earth’s forests. <br />
  8. 8. Pollution<br />Introducing harmful substances into the environment<br />Exists in:<br />Air <br />Water <br />
  9. 9. Coral Reef Destruction<br />“Bleaching” <br />Coral loses color due to stress from changing environmental conditions/temperatures<br />Due to human activities and waster pollution<br />Harms fishing<br />25% of marine life is threatened <br />
  10. 10. Importance…<br />Harmful to all people especially children and elderly<br />Better world for future generations<br />Less ozone depletion<br />Emissions of harmful substances in environment<br />Co2 (automobiles)<br />Industry<br />
  11. 11. Ozone<br />A gas in the stratosphere<br />Protects us from sun’s harmful ultraviolet light <br />
  12. 12. Depletion<br />Holes created in the ozone layer due to human activities<br />Dangerous gas <br />Speeds greenhouse effect <br />Trapping of sun’s warmth into earth’s atmosphere <br />Gases such as CO2 and methane cause this<br />Causes earth’s temperature to rise<br />Global warming contributor<br />
  13. 13. Importance…<br />Damage plant life cycles <br />food chain disruption<br />All life will be threatened<br />Health problems<br />cancer<br />Damages environment<br />Greenhouse effect increase<br />Causes global warming to speed up<br />
  14. 14. Methods of Reduction<br />Use less<br />Create and use environmentally friendly products<br />Laws enforcing use of less harmful goods<br />Widespread awareness<br />
  15. 15. Conclusion…<br />With knowledge and motivation we can make the world a safer place!<br />Humans create many problems in the environment<br />Coral reef destruction, deforestation, pollution, etc.<br />These can damage health and disrupt life cycles<br />Our world uses renewable and nonrenewable resources everyday<br />some can be recreated, others take millions of years<br />
