When you travel to less fortunate countries. Two years ago, I had the amazing opportunity to travel to Cuba with the music department. Where it was an amazing trip, I couldn't help but feel devastated at every turn when I saw poor, emaciated and in many cases miserable horses struggling to work through the day. Everything from cart horses to pull tours to horses that are actually the people's mode of transportation to ponies being galloped around the marketplace.
Now, I had such torn feelings. One one hand, these poor animals are in horrible conditions... but on the other hand, the people can't help it. They rely on these animals to get them places (and I saw many a yearling or YOUNGER pulling a cart), to get them to the small jobs they have, and they don't have access to food for THEMSELVES, never mind the animals.
And the arguments that work here don't apply there, either! You can't say "well if you can't afford them, don't get an animal" because without these wondrous animals these people would most likely die from lack of funds. Yes, Cuba is communist... but in order to get your "fair share" in a communist country, you need to do your part for society. To do this, they need to get to their jobs or work their fields, and to accomplish that they need these animals because cars are NOT readily available to citizens there. What cars are available aren't very new, either.
Sometimes, such as the case with tour guides, the horses ARE the people's job. No horses... no job... no money, no food, no clothing, death.
It was a very life-changing experience. I would go back there any day, I had so much fun... but that was a big turn-down. I just felt like sharing. Witnessing animals in this condition so first-hand really gave me a huge kick to step forward into actively helping the ones it was possible to help.
And to lighten the mood, my favorite picture from that trip... me standing fully clothed out in the ocean.
