Supreme Court Justice William Douglas defined “person” in 1972 Sierra Club vs. Morton
“The ordinary corporation is a “person” for purposes of the adjudicatory process… So it should be as respects to valleys, Alpine Meadows, rivers, lakes, estuaries, beaches, ridges, groves of trees, swampland… All forms of life will stand before the court – the pileated woodpecker as well as the coyote and bear, the lemmings as well as the trout in the stream.”
Sierra Club v. Morton, quoted in Troy Clark, Ph.D. Abortion Every 90 Seconds: The Whole Story (Kindle, 2015)
The Supreme Court has also ruled that the baby below is NOT a person and can be legally killed.
