the airways within the trees until they are dead. Once a pine beetle enters a tree, that tree cannot be used for manufacturing purposes; making paper, building houses, tables, etc. Usually mountain pine beetle populations are kept at a good rate by very wet summers, harsh winters, and cold springs, which kill a part of the population before it gets too far north, but because of climate change, the winters are getting warmer and the summers are getting dryer. During the cold winters, most of the pine beetle population would die, but because of climate change, these beetles are over populating since winters are no longer cold enough to kill these beetles. They are now able survive in areas where the could not have lived in the past. The mountain pine beetles are making its way up north and are going to make it to the forests of Alberta.
