Reusable Resources - Recycling
Reuse:
Recycle:
Recycling reduces the dependence on raw natural resources.
Recycling reduces the cost of production – less refining and processing of raw materials.
Pre-Production Recycling:
Post-Production Recycling:
Resource Management
Maintaining a balance between resources, production (use) and capacity (demand).
Over-exploitation
Reducing production
More efficient production
Resources and Development
Developed vs. Underdeveloped: terms describing economic, social and institutional growth of national states.

China’s Natural Resources
Agriculture: rice, wheat, corn, cotton, barley, tobacco, tea and sugar cane, timber
Mineral Resources: aluminum (8.2%), antimony, coal (29%), crude oil (5%), iron ore (14%), lead (19%), magnetite, manganese (17%), mercury, molybdenum, tin (32%), tungsten (75%), uranium, vanadium (25%), zinc (14%)
Large potential for major natural resources and resource exploitation, world's largest hydropower potential
China & Resource Use
Abundant natural resources
Growing global economy
Huge population: 1,346,000,000 people (2011)
Results in high demand on natural resources.
Much of the country is underdeveloped, but is moving rapidly towards developed.
What will happen when China becomes a fully developed nation?
