School project - The Vanishing Forests.
The material needed for the project involves causes and effects, search for solutions, and major issues in Canada.
I'd appreciate information, links, etc.
It's for a grade 11 History class.
Let me know! =)

check out http://www.forestrycanada.com/
http://www.nationalgeographic.com/eye/deforestation/deforestationintro.html has some pretty good videos
http://cfs.nrcan.gc.ca/news/588
A good text is Environmental Science by Daniel D. Chiras. It has a chapter on Forests and Forest Management. There is a section on the root causes of global deforestation pg. 232...you can view this text at http://books.google.ca/books?id=_3zLQvhENVMC&pg=PA232&dq=deforestation+canada#v=onepage&q=deforestationcanada&f=false.
Look at other introductory environmental science texts. You should be able to find lots of information.
hope that helps

Environmental Pollution Effects on Trees and Plants
Air Pollution
• Acid rain can kill trees, destroy the leaves of plants, can infiltrate soil by making it unsuitable for purposes of nutrition and habitation
• Ozone holes in the upper atmosphere can allow excessive ultraviolet radiation from the sun to enter the Earth causing damage to trees and plants
• Ozone in the lower atmosphere can prevent plant respiration by blocking stomata (openings in leaves) and negatively affecting plants’ photosynthesis rates which will stunt plant growth; ozone can also decay plant cells directly by entering stomata
Water Pollution
• May disrupt photosynthesis in aquatic plants and thus affecting ecosystems that depend on these plants
• Terrestrial and aquatic plants may absorb pollutants from water and pass them up the food chain to consumer animals and humans
• Plants may be killed by too much sodium chloride in water
• Plants may be killed by mud from construction sites as well as bits of wood and leaves, clay and other similar materials
• Plants may be killed by herbicides in water; herbicides are chemicals which are most harmful to plants
Soil Pollution
• May alter plant metabolism and reduce crop yields
• Trees and plants may absorb soil contaminants and pass them up the food chain
