1. Resources and Human Impacts On Earth Systems

2. Renewable Resources Any resource that can be replenished naturally over time. Examples: Wood energy Solar energy Wind energy Water

3. Nonrenewable Resources Any resource that can’t be recreated on a scale compared to its consumption. Made by nature Examples: Oil Coal Natural gas

4. Benefits… Renewable Resources Nonrenewable Resources Less Pollution Naturally replenished Environmentally friendlier Avoid depletion for future Necessary for life Provides better energy than renewable resources More functional

5. Costs… Renewable Resources Nonrenewable Resources Not practical Hard to maintain Expensive overused Will eventually run out Can’t be remade Can’t be replenished Takes millions of years to be made

6. Impact Of Humans On the Environment Deforestation Pollution Coral reef destruction Erosion Invasive species And many more!

7. Deforestation Cutting down and/or burning of Earth’s forests.

8. Pollution Introducing harmful substances into the environment Exists in: Air Water

9. Coral Reef Destruction “Bleaching” Coral loses color due to stress from changing environmental conditions/temperatures Due to human activities and waster pollution Harms fishing 25% of marine life is threatened

10. Importance… Harmful to all people especially children and elderly Better world for future generations Less ozone depletion Emissions of harmful substances in environment Co2 (automobiles) Industry

11. Ozone A gas in the stratosphere Protects us from sun’s harmful ultraviolet light

12. Depletion Holes created in the ozone layer due to human activities Dangerous gas Speeds greenhouse effect Trapping of sun’s warmth into earth’s atmosphere Gases such as CO2 and methane cause this Causes earth’s temperature to rise Global warming contributor

13. Importance… Damage plant life cycles food chain disruption All life will be threatened Health problems cancer Damages environment Greenhouse effect increase Causes global warming to speed up

14. Methods of Reduction Use less Create and use environmentally friendly products Laws enforcing use of less harmful goods Widespread awareness

15. Conclusion… With knowledge and motivation we can make the world a safer place! Humans create many problems in the environment Coral reef destruction, deforestation, pollution, etc. These can damage health and disrupt life cycles Our world uses renewable and nonrenewable resources everyday some can be recreated, others take millions of years
