Stop Tree Migration Due to Global Warming

Trees are the latest species seeing shifts in migration patterns due to global warming. In a study led by the U.S. Forest Service, 11 out of 15 northern-species trees shifted on average more than 12 miles north from their older counterparts.
Forest ecosystems are an extremely important natural resource to the U.S., considering that one-third of the nation's lands are forests. But the altered migration patterns could change this. According to the study's projections, U.S. species such as the yellow birch could move well beyond the Canadian border by the early 2100s.
Not only does the shift in migration of trees threaten the biodiversity of the forests and our nation's reliance on the natural resource, but it also reflects the undeniable presence of global warming and the changing of our world. Tell Congress to help protect our forests - and our earth - from global warming.
Dear Congressperson,
According to a recent study led by the U.S. Forest Service, trees are now seeing shifts in migration patterns due to global warming effects. The study found that 11 out of 15 northern-species trees shifted on average more than 12 miles north from their older counterparts. I am concerned about these recent findings for several reasons.
First, the findings reinforce the undeniable presence of global warming and the changing of our world. The evidence from this study brings to light how strong of an effect our actions have on our environment - our abuse of the earth is causing natural cycles in migration and in ecosystems to shift.
Secondly, forest ecosystems are an extremely important natural resource to the U.S., considering that one-third of the nation's lands are forests. But the altered migration patterns could change this. According to the study's projections, U.S. species such as the yellow birch could move well beyond the Canadian border by the early 2100s.
Third, the migration of trees threatens the productivity of forests as well as the biodiversity dependent on these ecosystems.

Please take note of these effects and use your power in Congress to pass laws to halt the human contributions to climate change.
