"The nation behaves well if it treats the natural resources as assets which it must turn over to the next generation increased and not impaired in value."
"1984 as the Year of the St. Lawrence Seaway and June 27, 1984, as St. Lawrence Seaway Day."
"Our Nation has a God-given responsibility to preserve and protect our natural resource heritage."
"Preservation of our environment is not a partisan challenge; it's common sense."
