Many
goods are made from non-metallic minerals include cups and
plates, plastic bags, fertilizers, and glass. These minerals
require a lot of processing to obtain useful products such
as paint, glass and plastics. Other minerals are not used
to make products directly but are used to produce energy which
is then used to make things. All impact upon the environment.
Natural mineral resources, such as oil and coal will eventually
become exhausted.
