1. Humans & the Environment

2. What do you think would be the consequences of exceeding Earth’s carrying capacity for the human population?

3. Shortages of food, water, and fuel
Overcrowding
Shortages of food, water, and fuel
Malnutrition
Increased disease

4. What role does the forest play in the environment?

5. Provides habitats & food
Makes products
Removes CO2 & produces 02
Stores nutrients
Provides habitats & food
Limits soil erosion

6. “Tree Be Gone” Activity
Get supplies from the back table.
1 foil pan with soil
1 bag (100 craft sticks & 4 cards)
Select a card from the plastic bag.

7. “Tree Be Gone” Activity
Set up your activity.
Place 50 craft sticks in the foil pan. This represents an entire forest.
Give the other 50 craft sticks to the forest manager.

8. “Tree Be Gone” Activity
Timer
Call “time” every 15 seconds
Forest Manager
Place 2 craft stick into the forest
Logger(s)
1st “Time”: remove 2 craft sticks from the forest (1 per logger)
2nd “Time”: remove 4 craft sticks from the forest (2 per logger)
Next “Time”: remove 6 craft sticks from the forest (3 per logger)
So on!

9. Let’s Check & View What happened in this activity?
What are some things we could do to solve this problem of running out of resources?

11. Renewable & Nonrenewable Resources
Can Regenerate & be replaced
Not necessarily unlimited
Nonrenewable Resources
Cannot be replenished by natural processes

12. Examples Renewable Resources Tree Corn Water Soil Fish Chicken Oxygen
Nonrenewable Resources Coal Natural Gas Oil Copper Iron
