Perhaps the most famous rare animal is the panda。Twenty years ago it was nearly extinct。Now，its numbers are growing again。It is become a symbol for wildlife conversation。But many other species have less lucky than the panda。Some are already extinct。Today，many more are in serious danger。This is because man hunts them，and destroys their habitat 。Is it too late to save wildlife？
   A serious habitat problem arises because of pollution or opening;new lands。Habitats take many years to grow again。When the wild animals lose their home，the natural balance is also changed。If one animal，bird，or insect disappears，all the others suffer，too。
   This is what is happening in the rain forests of South America，Africa and Asia。These are some of the world's oldest habitats。But the problem doesn't stop there。Habitats and animals are disappearing in Europe，too。Since 1947 in Britain，for example，50% of the woods，low wet land，and 95% of meadow have disappeared 。And what has taken the place of these green，natural places？Houses，farms，cities，streets，roads，and factories。Because of this several British species are dying。     Then，what is the solution？There is only one way to save animals and wild habitats——conversation。This means man should protect animal in danger by law，open more national parks，build fewer new roads，plant more forests，and cut pollution。If this doesn't happen，many wild animals will soon have just one habitat——the zoo.
