You'd have to find people willing to take them, transporting them, slaughter them, and distribute the meat.
We are talking about slaughtering and butchering millions of animals in a non-factory setting, not practical. On top of that transporting animals and/meat at that scale is not cheap or easy.
This sort of operation is very difficult to do on an ad hoc/emergency basis.
If an organization would just pick up any unwanted animals on demand, I'm sure the farmers would be happy to hand them over.
I think we should go even farther with our euphemisms and call it "harvesting a resource".
I love meat, even though I consider killing animals unethical, which makes me a hypocrite. Still, I think the least we can do is call the process "killing an animal".
I would hope that everyone understands that creating a final meat product involves killing, but we shouldn't trivialize the process requirements just to drive an emotional point home.
I haven't done larger animals from the killing but have butchered large cuts of meat. It is a time-consuming process while being physically tiring.
Also, ethics aside, the comment above was referring specifically to processing, not the act of killing. Killing is comparatively fast and far less messy. Butchering/processing a 300lb carcass is where the real effort lies.
There's a lovely book called Everything I Want To Do Is Illegal that I think every American who eats food or votes should read.
"Drawing upon 40 years' experience as an ecological farmer and marketer, Joel Salatin explains with humor and passion why Americans do not have the freedom to choose the food they purchase and eat. From child labor regulations to food inspection, bureaucrats provide themselves sole discretion over what food is available in the local marketplace. Their system favors industrial, global corporate food systems and discourages community-based food commerce, resulting in homogenized selection, mediocre quality, and exposure to non-organic farming practices. Salatin's expert insight explains why local food is expensive and difficult to find and will illuminate for the reader a deeper understanding of the industrial food complex."
from https://www.bookdepository.com/Everything-I-Want-Do-is-Illeg... makes me think, given the implied negatives of child labor regulations and food inspection, that anyone reading that book should follow up with a quick read of The Jungle by Upton Sinclair, the same way that I found Oliver Twist a useful tonic after my first exposure to Atlas Shrugged.
It's amazing how quickly you assume that the way those laws apply to Joel's farm is reasonable, or that what Joel is doing is the sort of thing the public were interested in interfering with when they supported those laws.
Your reflex to defend the application of laws by their title is why no matter how much stink is made by people who actually read the US PATRIOT or EARN IT act for example, or any number of other brilliantly-framed pieces of legislation, there is always a gallery of opinionated people who will gladly judge a book by its cover with no less certainty, and with even more smug self-importance, than they would by its content.
If it has never occurred to you: not everyone impacted by the law is a crook.
and processing comes before transportation concerns right
