When studies indicated the proposed jetport would create 4,000,000 US gallons (15,000,000 L) of raw sewage a day and 10,000 short tons (9,100 t) of jet engine pollutants a year, the national media snapped to attention. Science magazine wrote, in a series on environmental protection highlighting the jetport project, "Environmental scientists have become increasingly aware that, without careful planning, development of a region and the conservation of its natural resources do not go hand in hand".[98] The New York Times called it a "blueprint for disaster",[99] and Wisconsin senator Gaylord Nelson wrote to President Richard Nixon voicing his opposition: "It is a test of whether or not we are really committed in this country to protecting our environment."[97] Governor Claude Kirk withdrew his support for the project, and the 78-year-old Marjory Stoneman Douglas was persuaded to go on tour to give hundreds of speeches against it. She established Friends of the Everglades and encouraged more than 3,000 members to join. Initially the U.S. Department of Transportation pledged funds to support the jetport, but after pressure, Nixon overruled the department. He instead established Big Cypress National Preserve, announcing it in the Special Message to the Congress Outlining the 1972 Environmental Program.[100] Following the jetport proposition, restoration of the Everglades became not only a statewide priority, but an international one as well. In the 1970s the Everglades were declared an International Biosphere Reserve and a World Heritage Site by UNESCO, and a Wetland of International Importance by the Ramsar Convention,[101][102] making it one of only three locations on Earth that have appeared on all three lists.[103]
