Some natural resources can be reproduced
within a few years or decades. These are called renewable
resources. Trees are an example of a renewable resource.
Oil, minerals, and soil take hundreds, thousands and
even millions of years to be made. These are called
It is very important we use renewable
and non-renewable resources wisely. If a resource is
used and thrown away, eventually the resource becomes
scarce. When the supply dwindles, its price will increase.
Products that are made from that resource would increase
in price too.
Sometimes resources become so rare
they can no longer be used. In these cases, substitute
resources may be used, which may make a poorer quality
product, or one that is more expensive. If substitutes
can not be used, some products could no longer be made.
Wise use of resources includes not
throwing away products that are reuseable or recyclable.
When these products are reused or recycled, it maintains
resource availability, uses less landfill space, and
uses less energy.
