Cities sprawl and use up wilderness

A park tries to be big enough
to allow food chains to survive.

Fences keep animals in
(and away from farmland)
and poachers out.

Ecotourism pays for the cost of the park

Tourists can upset nervous animals
and so some areas must be left undisturbed.

Cutting down trees
takes away animal homes.

Wild animals are thought
to threaten farmers crops and animals.

Poachers hunt animals
just for fur, ivory etc.

Farmland is a desert for many wild animals
because they cannot eat what is grown.

During war
desparate people may kill
park animals for food.
Parks are difficult to protect
in unstable countries.
