A Sad Fact I Didn't Know

There are 500,000 American bison in the United States and Canada. Most of them are being raised to fulfill the demand for bison meat, seen as a leaner alternative to beef (Pro tip, if you buy some, serve it rare - it dries out much faster than beef).

What I didn't know?

Less than 20,000 of them are actually pure bison. Apparently, bison will interbreed with domestic cattle and produce fertile offspring - so bison genetics have been contaminated by European cattle. I think this is a very sad thing.
