saving a horse or the planet

This is Brooke. She lives across the street from us in a teensy weensy little corral. I have felt bad for this horse since I've been here, but mostly don't do anything about it. Occasionally his Artness and I will feed her carrots, but that seems like so little for an animal who lacks companionship and a place to run.
Today, I went over and brushed her. I could tell she liked it; she made sure that I could reach every part of her through the fence.
Brooke made me realize that sometimes you can't change a crappy situation, but you can help a little - especially if you don't let the pain get you down and just give what you can.
