9.2  Ecology - A Survival Guide



http://www.firstpeople.us/pictures/wolves/1024x768/Wolves-001-1024x768.html

Wolves – animals that get a very bad name in fairy stories, myths and legends and from farmers in many parts of the northern hemisphere.   (Remember “Little Red Riding Hood”, “The Three Little Pigs”,  “Werewolf” and so on?)   In some parts of the world where wolves have been exterminated they are now being reintroduced (such as in Northern Wisconsin and Yellowstone National Park) for the benefit of other things that live there.   Their presence in many of the wild places still remaining is essential to the health of those environments.


INTRODUCTION  The human population is growing.  More and more humans means more space for buildings, roads and agriculture.  That means less and less space for other organisms and the loss of many kinds of living things.  Scientists are seriously worried about the extinction so many different kinds of animals and plants - but why?  Does it matter?  Can we live without wild things and wild places?

How do living things depend on each other?

What special features do animals and plants have so that they can live in different places?

How can life have existed on Earth for billions of years?  Why don’t the things they need to live, run out?

How do living things in Australia survive drought and flood?

These are some of the questions we try to answer in this topic.
