Turns out trees really are important

I have a love/hate relationship with trees.  On one hand they filter huge amounts of pollution from the air, but on the other hand they produce pollen which makes my eyes swell and air sacs hurt.

In the past ten years or so 100 million trees have died due to a beetle in the MidWest and Eastern sections of the US.  A rise in cardiovascular and pulmonary disease has been directly linked to the loss of these free “HEPA filters” nature has provided.

I recently read an article labeling Louisville, KY as America’s fastest warming city.  The main contributing factor to this rise in temperature is a lack of tree cover.  Who would have thought shade was that big of a deal?  We’ve in the process of taking down some dead trees where we live.  I want to make sure we plant some new ones to replace the air filters.
