Problems of Input (Resources) by Mind Map: Problems of Input (Resources)

1. Arable land ↓ drastically

1.1. Climate Change

1.2. Soil degredation

1.3. Water Shortage

2. Rising population

3. Land

4. Minerals

4.1. Use has doubled/peaked in areas of the world

4.1.1. Recycling is critical to maintaining sources

5. Forests

5.1. Hectares ↓ drastically

5.1.1. lumber

5.1.2. source of water circulation

5.1.3. maintain biodiversity

5.1.4. major source of oxygen

5.1.5. fuel

6. Water

6.1. serious water shortages

6.2. not evenly distributed

6.2.1. areas of shortage have poor sanitation

6.3. large use in agriculture → source damage (salination)

7. Soil

7.1. Natural Habitat= soil is regenerated & recycled

7.2. Agricultural habitat = degraded

7.2.1. Fertilizers→ volume &nutrient loss

7.2.2. Pesticides→ volume, nutrient & biodiversity loss

7.2.3. Irrigation→ volume, nutrient & biodiversity loss & salination

7.2.4. Industry is reliant on oil

8. Food

8.1. Global Food Crisis

8.1.1. Loss of top soil

8.1.2. ↑ water shortage

8.1.3. ↑ temperature

8.1.4. ↑ population

8.2. # of chronically undernourished ↑

8.3. Food security large concern

8.3.1. having reliable access to a sufficient quantity of affordable, nutritious food

9. Energy

9.1. Global Oil Depletion (peak likely before 2030)

9.1.1. Oil use is vast: heating, transport, plastic etc.

9.2. Coal may take over

9.2.1. destroying forest and farmland through extraction

9.2.2. produces 25-55% more carbon dioxide

9.3. Nuclear Power Solution?

9.3.1. expensive to build

9.3.2. hazardous waste cannot be stored indefinately

9.4. Renewable resources?

9.4.1. no alternative has the energy density and portability as gas

10. What is the current state of civilization?

10.1. human well-being

10.1.1. Material Safety

10.1.2. Good Health

10.1.3. Safety & Security

10.1.4. Good Social Relations

11. Resources (Inputs)

11.1. sustainable rate of use can be no greater than the rate of regeneration/recycling

12. Emissions

12.1. Sustainable rate of emission can be no greater than the rate at which the pollutant can be recycled, absorbed etc.

13. Collapse

13.1. Rate of resource use & Emissions exceed Regeneration and Recycling
