1.1 Q: 1
State the 3 principles of Sustainability and describe how they are key to long-term sustainability of life on this planet.
|
1) Reliance on Solar Energy -supports photosynthesis -powers indirect forms of solar energy (flowing water, wind)
2) Biodiversity -variety of life forms, natural systems (deserts, forests, oceans etc.) and natural services (renewal of soil, air and water purification etc.)
3) Chemical (nutrient) cycling -chemicals circulate between environment and organisms -ensures that there is air, water, soil and life

1.1 Q: 2
Define resource, particularly perpetual, renewable, sustainable yield and nonrenewable |
1) Resource: Something taken from the environment for human benefit
2) Perpetual: Supply is continuous (solar energy)
3) Renewable: Replaced through natural processes (if nature can renew this resource faster than humans use it up)
4) Sustainable Yield: Fastest rate a renewable resource can be used without reducing the available supply
5) Nonrenewable: Fixed quantity, on a human time scale these resources can be used faster than nature can replace them...these resources are limited. |

|
1.1 Q: 3
Compare and contrast natural capital, natural resources and natural services. |
Natural capital = natural resources + natural services
1) Natural Resources: materials in the environment that humans depend on -renewable: air, water, soil, plants, wind -nonrenewable: copper, oil, coal
2) Natural Services: Processes in nature which support life and human economics example: purification of air or water, renewal of topsoil
3) Natural Capital: Supports earth's diversity of species but natural resources must be used in a sustainable fashion |
|
|
1.1 Q: 4
Define reuse and recycling |
1) Reuse: Using a resource repeatedly while it is in its same form (Filling and refilling glass bottles)
2) Recycling: Collecting waste and turning them into new materials |
|
|
1.1 Q: 5 Describe what a healthy (stable) vs. Unhealthy (unstable) ecosystem would be like. |
ecosystem: set of organisms that interact with each other, their environment and nonliving matter
healthy: balance -biodiversity -solar energy -natural resources and services -chemical cycling
unhealthy: imbalance -using renewable sources faster than they can be replaced by nature -loading bodies of water with chemical and animal wastes faster before they can cleanse themselves -not using resources in sustainable fashion

|
1.1 Q: 6
Describe the limitation of earth to provide endless resources. |
Nonrenewable sources (copper, coal, oil etc) cannot be replaced within a human timeline and can be depleted much faster than nature can renew them. |
|
|
1.1 Q: 7
Recognize more vs. less developed countries.
|
1) More: higher GDP per capita (U.S.A. Canada Japan, Australia, New Zealand, and European countries)
2) Less: Africa, Asia, Latin America, Haiti, Nigeria, Nicaragua
3) Middle - income: China, India, Brazil, Turkey, Thailand and Mexico |
