What are the things that can be transformed to produce benefits (Chan, 2016)
materials, water, energy, minerals, and others
classification of natural resources
renewable and
nonrenewable resources
solar energy, air, wind, water, tides, flowing, soil, and plants are classification of what resources
renewable
fossil fuels, non metallic minerals, and metallic minerals are components of what classification of resources
nonrenewable
•Can be used repeatedly and does not run out
because it
is naturally replaced
•resource that can replenish itself at a similar
rate to its
use by people.
Renewable Natural Resources
•are those whose exploitation eventually reaches a
level beyond which regeneration will become
impossible.
•Such is the case with the clear-cutting of tropical
forests (OECD, 2001a).
