The historical record proves this absolutely false. The Convention on Nature Protection and Wild Life Preservation in the Western Hemisphere committed the entire American economy and all its land to the preservation of EVERY species. It was ratified in 1941 by voice vote without record of a quorum and no committee debate.
Anyone who doubts the mischief that can be done by the Senate ratifying treaties should Google “desertification treaty” and see how the late Wyoming Senator Craig Thomas was supposedly “tricked” in allowing this harmful treaty to become US law in a late night session.
