Less trees affect us all


Trees in the western United States are in trouble because temperatures are on the rise and there are drought-like conditions in this region. Warmer weather and decreased water supply mean dwindling forests are no longer absorbing greenhouse gases and this makes them more vulnerable to pests and fires. Studies have shown that in areas where temperatures rose by one degree Fahrenheit and average rainfall and snow pack runoff decreased; trees have a higher mortality rate. These areas include the Pacific Northwest, California, and the inland Western States. The growth rate for trees has not changed, so the forests are losing trees faster then they are being replaced!! Therefore, forests will be comprised of mostly fewer, smaller trees. These smaller trees are not able to convert as much CO2 as the larger trees. Animal species depend on the trees to convert CO2 to oxygen. So these habitats with smaller trees would no longer be an acceptable living area for certain species.

Analysts are unsure if the warming temperatures are a result of global warming or just part of a natural climate cycle. One thing is for sure, the trees are in danger and something needs to be done to help them. http://http://www.nytimes.com/2009/01/23/us/23trees.html?ref=science

In my opinion, this article was very informative and it made me think about the damages warming temperatures are causing. Trees are crucial to the survival of humans, and how do we repay them, by killing them. And by killing the trees, we also damage everything else on earth, because all living things depend on trees and plants to supply a clean, breathable supply of oxygen. If all of us take action to help this cause, we can guarantee a brighter future for us and trees to come.
