This sounds nice, but, as others already mentioned, the source is an email which might not be credible.
This does remind me of an article I read several years ago. During the “Arab spring,” Egypt decided to abolish all pigs in the country. Since the pigs primarily ate garbage and the garbage was now being thrown away in the trash, rats and mice proliferated. Yeah, pigs have their uses even for those who don’t eat pork. And for those who do, pork is an inexpensive meat.
Catfish are also 'bottom feeders' who ingest wastes and process it into delicious meat. I see that as another of God's gifts to us.
More barbecue for me heck yeah!
