Problems and Concerns caused by Human Influences on the Environment
Natural Resources
Natural resources are the animals, plants
and natural features of the Earth which humans use to support
their lives and their needs. The natural resources of the
world include the forests, which provide us with wood, and
animal life, such as fish, which we take from the sea. There
is a great danger that we are using up these natural resources
too quickly.
In some cases there are things we can do to
prevent disaster. In the case of the forests, we can make sure
that we plant as many trees as we chop down. This will
guarantee a constant supply of wood.

FACT 1 |
Since
the beginning of the 18th century the Earth has lost
over 6 million square kilometres of forest. This is
equivalent to an area of land greater than Europe. |

FACT 2 |
The
area of cultivated land in France rose from half a
million hectares in 1959 to three million hectares in
1993 - this is a 500% increase. |

FACT 3 |
At
the beginning of the 20th century Brazil was covered
by 20 million square kilometres of forest. By the end
of the 1980's over half of the Brazilian forest had
"disappeared". |
