Trees have a symbiotic relationship with humans. And with my dog Buddy.
In order to live, we inhale Oxygen and exhale Carbon Dioxide.
In order to live, trees take in Carbon Dioxide and release Oxygen.
I have lived in Green Valley for 20 years and have never understood homeowner associations fights about trees. In fact, I wondered then, why they called it "Green Valley" when they were so "anti" tree. I don't buy the argument "I paid for the view and I don't want any g--d--- tree interfering with my view". Many times I have stood in the complainers patio, looking at the offending tree. There was not one time that moving a few feet to the right -or to the left that the view was obstructed. IMO
