Citation preview
You are walking through a lush forest. A soft cushion of needles keeps your foot steps silent. You smell the trees. You hear chipmunks in the branches. Birds dart back and forth. This is a
beautiful place. But the trees may soon be cut down for lumber and paper. Can we keep our forests and still have the products we need?
Natural resources are living things from the Earth that living things need.Trees are an example of natural resources.Trees are also an example of a renewable resource.Renewable resources are resources that can be replaced in a fairly short time.
A nonrenewable resource is a
resource that cannot be replaced.
Many natural resources come from
below the ground.
Miners dig into the ground to get
rocks called ores.
Ores contain metals and other minerals that people use.
Copper, iron, and aluminum are some useful metals. Hematite is an ore that contains the metal iron.
Some natural resources are not used
up.
Plants need sunlight, air, and water to
grow.
We need air to breathe and water to
drink.
These resources are not used up.
Sunlight, air, and water are always
available.
When people walk instead of riding in a car, they save fuel. When they choose products that have less packaging, they save paper and plastic. There is less garbage. Saving in these ways is called conservation.
Conservation is the wise
use of natural resources so
that people do not waste
them or use them up.
