Sustainable Management of Natural Resources
Aided by technological development
E.g.: use of solar power reduces the use of fossil fuels to generate energy
Sustainable management
HOW: 4Rs
Recover: Turn waste into useful materials
Recycle: Turn used resources/materials into new ones
Reuse: Use a resource again
Reduce: Use less of a resource
DEFINE: Use of resources in such a way that the needs of current and future generations are met.
Natural Resources
DEFINE: Useful materials produced by natural processes
2 types
Non-renewable-- resources that may not be replenished or if they are, process of replenishment occurs over a very long period of time; limited
Examples: coal, crude oil,
Renewable - resources that are replenished naturally within same time period they are used; limitless
Examples: solar energy, tidal energy, wood,
Can become non-renewable - it is used faster than it can be replenished. E.g. trees in tropical rainforests are cut down faster than the trees can regrow.
Due to human-centred view in which the physical environment is deemed important because of its usefulness to people
