Apparently there's an environmental/legal movement to grant/recognize rights of natural features, such as rights. I'd guess it's an attempt by lawyers to sue on behalf of such entities against pollution, etc. There's controversy, as might be expected, including conflicts with the LBGQ community, which seems to be the subject of this politico post.
But what intrigued me was the phrase in the post--"natural persons". I thought of the granting of rights to "legal persons"--corporations which has recently been expanded.
Why couldn't we have a constitutional amendment to the effect that nothing in the Constitution requires that "natural persons" and "legal persons" be treated the same?
