Endangered or Extinct?

• The number of people in the world is growing at
  an alarming rate.
• But this is not true for all animals.
• In some cases, there are only a few of one type
  of animal left in the wild. These animals are
  endangered, or at risk of dying out.
• If they die out completely, they become extinct.

15
Why does this happen?

• There are lots of reasons why animals become
  endangered or extinct.
• The most common are
• loss of habitat (forests cut down, rivers drying
  up).
• pollution poison the animals.
• hunting (for sport, their fur, tusks or meat).

Caring for the Environment

• It is in our own best interests to look after the
  world we live in.

  gone forever!
