Fish eat coral, cat eat's fish, dog eat's cat, bear eats dog.
Its how it works. Im certain the nautral process of consuming other animals isn't bad for the enviroment. If it is. The rest of the animal cycle is messed up.
You are right, in the natural process, predator animals eating prey animals isn't bad for the environment. But the feedlots and row upon row of chicken sheds, hundreds of pigs in barns and fish pens aren't the natural process. And all of those cattle in the feedlots add concentrated feces and urine to the ground and it leaches into the ground water. Same with the waste of chickens, pigs and the salmon in fish pens on the Pacific coastline. As far as human health is concerned, eating meat is not a natural process either, we are simply accustomed to it but our physiology is more like a herbivores than a predators.

[Choosing a nonvegetarian lifestyle has a significant health and medical cost. The total direct medical costs in the United States attributable to meat consumption were estimated to be $30-60 billion a year, based upon the higher prevalence of hypertension, heart disease, cancer, diabetes, gallstones, obesity and food-borne illness among omnivores compared with vegetarians (2). ] from The American Dietetic Association.
The point of all this is that the consumption of horses is not normal, a necessity, nor is it acceptable just because some people choose to do it. So from that perspective, speaking out against it is good, not only for horses, but for those who eat them. But at the same time, it is necessary to educate people so that they begin to realize that breeding and adding horses to the pool of unwanted animals isn't acceptable. And yes, you are right, animals should not be neglected and left to starve in fields since that appears to be a major concern of some of you, but that happens anyway even though the slaughter of horses is still going on.
I want to take a second here to thank you all for the politeness that I have encountered on this thread. Sometimes when people are looking at an issue from different perspectives, it can get a little heated, but I think that we've done an amazing job of getting along don't you?
