I think this racing business has to be fixed in the US, because there are altogether too many injuries and fatalities. The horses are started way too early and bred without regard for their long term endurance.

I think that it is also high time to start slaughtering horses within the states. It is wasteful to either euthanise every horse that's born in due time, or to ship them off over long distances to their end. Horses are good food, and actually quite wholesome.
