Look, sentiment is nice, but reality is nicer. Why not raise money for the trees' care? Because in this day and age, as long as you mean well, you don't actually have to DO well. It's like wearing a colored ribbon to support a cause. It doesn't do any good, but it is easier than working for that cause and it makes you feel better.
Ironically, these same Auburn students have a tradition of "rolling" these trees to celebrate something at the university, like a win in football. These trees would be covered in hundreds, if not thousands, of toilet paper rolls, so much so that the trees look iced over and the ground is covered in piles of unrolled toilet paper. The tree huggers have asked students to stop rolling, as it might hurt the trees. Never mind the fact that with every roll, a tree somewhere else had to die.
But hey, as long as everyone feels good, it's OK, right? Maybe they should be given a Nobel Peace Prize for all of their symbolic work.
