1. Resources and Human Impact on Earth System
By: Kenzo Ariza-Uenishi

2. Human activities Deforestation Destruction of coral reefs
Intensive farming
Pesticide
Pollution
Ozone depletion

3. Burned and cut down trees Loss of biodiversity Reduced food source
Deforestation
Burned and cut down trees
Loss of biodiversity
Reduced food source

4. Destruction of coral reefs
coral reefs are home to 25% of all marine species
25% of coral reefs are threatened in the world
2050 - lose up to 70% of coral reef

5. Intensive Farming Is the latest technique used yield high productivity
To produce more food
Use more fertilisers and pesticides
Destroys quality of soil

6. Pollution Pollute air and water by harmful substances

7. Pollution Eutrophication
Bacteria decay the dead plants and in so doing use up oxygen from the water
This means the fish suffocate and die
Lose food, habitat and Oxygen production

8. Pesticides Kill harmless insects and other animals Alter food chain
Pollute the water

9. Ozone depletion Dangerous gas Speeds Greenhouse effect
Holes created by the ozone layer due to human activities

10. !!! We need less Deforestation Destruccion of coral reef’s Pollution
Pollution
Ozone depletion
!!!

11. Human Development Index (HDI)
Measures a country’s average achievements in the areas of health, knowledge, and standard of living
HDI higher than 0.8 is considered "high human development“

12. What can we do ?? Organic farming Biological control pests
Organic farming
Biological control pests
Develop alternative energy sources
Less ozone depletion

13. Organic Farming
Is very important because don’t produce the pollution and problems of intensive farming

14. Biological Control of Pests
Using natural predators to eat pests instead of pesticides

15. Develop alternative energy sources
Solar power
Wind power

16. Conclusion
We need to save the planet Earth because we are using one and half planet
