m21.    Why is there controversy over old-growth deforestation?

Preservation costs lumber industry jobs; one in 10 jobs in Canada is directly related to forestry. Although these forests are, for the most part, managed by the National Forestry Service, violations of illegal practices (export of raw logs and domestic sale of raw logs) are not punished or not punished sufficiently. To protect these forests, preservationists have proposed several solutions:

e01.    What is biodiversity?

e05.    Where are National Parks located?

e06.    What is “wilderness” and how much do we have?

e08.    What are bioregions and biosphere reserves?

e09.    What is succession?

e10.    Why do organisms become extinct?

e15.    What was early life like?

e16.    What do computer models of greenhouse changes show?

e11.    What types of old-growth forests are there?

g04.    What causes climates to change?

g05.    How are forests of geological importance?
