I search why

I am writing about this subject with the motiviation of maybe helping educate people on what really is going on in the wild horse world. I have many questions on this subject. Starting with Is this rounding up for slaughter even legal? And if so what states allow it and what states don't. Another question being are there groups already trying to stop this nonsense and help get these horses that have been rounded up adopted? If so are they welcome to educating people on this matter? And lastly I wonder if there is anyway to stop this if it is happening, by maybe trying to bring the government in on it?
