get now let's hear from a few other witnesses there was a similar to this is used here at those desalination plant of the united states department of the interior in san diego california raw material for this conversion is salt water taken from the ocean it is right that these distillation chambers after hitting the rhine flows into the forest that relationship europe some of the salt water clashes in the steam which commences when it comes in contact with pipes that carry him leon heated salt water ryman goes into other chambers where clashes under pressure lower the map in the previous chamber the
the salt creek and that water is collected and the brine from the final stage of this process has returned to see the method of desalination employed in this plant is called multi stage flashing evaporation two and a half million gallons a day of fresh water used here other plans for diesel things you what are already in operation throughout the world in the future plans using nuclear energy would make the salvation more economical these plants would produce both fresh water and are changing the weather is another way in which the problem of water scarcity is being attacked seeding clouds with dry ice dropped from aircraft is one
way in which weather can be modified or precipitation can be artificially induced to supply additional water from the atmosphere in other ways by the use of ground based silver iodide generations under the right meteorological conditions cloud seeding will increase precipitation while leopard's continue to increase the water supply in arid regions we are also experiencing a problem of another sort of many areas this is the problem of water pollution why waste of industrial processes and bypass to these materials contain organic and inorganic chemical compounds and a variety of harmful microorganisms when these compounds decompose they act as nutrients switch or enrich the water
and promote the growth of small underwater plants called algae again lt wow the water of oxygen destroying aquatic life and preventing the water from purifying itself when ingested or other waterborne wastes may affect man because they are toxic some back to the pollution from these plants has affected the entire southern end of the lapel in many communities insufficiently treated sewage and industrial pollution very ugly but the beaches off limits to swimmers in the waters of green bay the north the pollutants are raw and partially treated waste from the windows and the cities along its short it

this hyper logical project at lake or reservoir is an experiment in a method of keeping the water where it is needed down in the way that there is a main water supply for the three hundred and fifty thousand inhabitants of oklahoma city this setup as an elaborate one involving a wide array of scientific disciplines evaporation is an elusive problem and a costly scientists have been struggling with evaporation for more than forty years back in the twenties they got rid of that michael evaporation here they are trying something now that seems to do the trick putting lipstick on the water exit of economics a soft like scene that you used as a base for lipstick doesn't smell it doesn't taste and mix of the water

stale why you learn infinitely when it adopted in nineteen sixty it's a land use law which withdrew from local government that our workers alliance a stable ally itself and one of the things they did was to designate all lands in the state which should be preserved for agriculture industry talking about something like this to come pretty close to home and this theory anyway the notion of putting rule where people want locally to govern themselves in a very fearful of giving up some of their power even a regional government level well it seems to native students suggesting that we usually substitute one resource for another the resources is a matter of fact there's not really not really agriculture after all is land and we're talking simply about to use to atlanta because you're suggesting agriculture i'm suggesting residential development we get into a subject to discussion whether you're uses that are minors better

paltry two percent two percent but ted what causes the remaining ninety eight percent people people oh a lot of people take nh as they can to put this goes into big business what science can't lie we all pollute the air all are smells and the sweats and are gases and belongings move at will poison into the skies but dr i thought toenails with alaska voters safe part of a woman but what can we do more products more sprays more appeals walk me was so we've got a pigeon they sprayed by rob ourselves until there's nothing left corinne corrina ammonia rob ammonia in our skin skin can

Program Description
Coinciding with a nationwide observance of Earth Day, NET will devote the entire public broadcast schedule to live coverage and special programming on the theme of our environment and the forces that threaten it. In its scope, it will be reminiscent of an old-fashioned telethon -- encompassing teach-ins, marches, demonstrations, and exhibits on campuses and in cities nationwide. NET's coverage of the events will be made possible by the most extensive use to-date of local affiliate stations. At present, the schedule is as follows: 3:30 to 4:00 pm EST -- Live coverage of activities in Philadelphia, Washington, and New York 4:00 to 6:00 pm EST -- Regular PTV program for children will deal with ecological themes and will form a part of NET's "Earth Day." These programs; "Sesame Street," "Mister Rogers," and "What's New." 6:00 to 8:30 pm EST -- Regular programming will be pre-empted. Live coverage of Earth Day activities in the East and Midwest will be interspersed with filmed and videotaped portraits of the problems besetting the environment. From Chicago, there will be a report on air pollution; from Madison, Wisconsin, a report on water pollution. Black ghetto dwellers in St. Louis will also present a play that has been written especially for Earth Day. 8:30 to 9:00 pm EST -- A special edition of "Book Beat," the weekly series originating from WTTW, Chicago. Its host, Robert Cromie, will interview Frank Graham Jr., author of "Since Silent Spring," the newly-issued study which updates the late Rachel Carson's finding on the use of pesticides. 9:00 to 10:00 pm EST -- This portion of the program will span the East, Midwest, and Far West. Tentatively, the schedule calls for excerpts from a special play by the San Francisco Mime Group. There will also be live coverage of the Survival Walk through the San Joaquin Valley. This 48-day trek dramatizes the extent to which people rely on the land for sustenance. Another segment planned for this hour is a short documentary on the internal combustion engine -- source of 60 percent of all air pollution. Technologists and members of interested groups will present their viewpoints on the engine and air pollution. NET Special -- "Earth Day" is a production of National Educational Television. Executive producer is Jim Karayn, Emmy winner for "State of the Union '69." (Description adapted from documents in the NET Microfiche)
Program Description
While NET's unprecedented "Earth Day" coverage explores the broad spectrum of what is happening to our environment, one segment of the program (8-8:30 pm, EST, April 22) takes a close look at an area where something can be done and the politics involved in whether anything will be done. This special documentary by NET producer John Wicklein focuses on the pressures exerted by the public agencies on industries to clean up their operations which cause pollution and the resistance of these industries to making costly changes. As a case study in the politics of pollution, Wicklein examines the automobile industry and its noxious internal combustion engine. Among those interviewed will be Edward N. Cole, President of General Motors; Sen. Edmund Muskie (D-ME); Secretary of Transportation John A. Volpe; Dr. Lee DuBridge, President of Nixon's science advisor; Rep. Leonard A. Farbstein (D-NY); and William Lear of Lear Motos, Reno, who is working on a gas turbine engine to replace the standard internal combustion engine. Efforts of the State of California to control auto pollution and the success and failures of these efforts will be covered. The documentary will be part of NET's executive Earth Day Programming which begins at 3:30 pm and runs until 10 pm EST April 22. Jim Karayn is executive producer.

Program Description
NET will cover events from coast to coast reflecting a national outpouring of concern about the deterioration of the environment as part of its all-day broadcast devoted to Earth Day on Wednesday, April 22. The unprecedented day of live coverage and regular programming on ecological themes -- the most extensive program of its kind ever attempted by public television -- will run from 3:30 pm to 10:00 pm EST, Wednesday, April 22, on some 180 public television stations. In its scope, it will be reminiscent of an old-fashioned telethon -- encompassing teach-ins, marches, demonstrations, and exhibits on campuses and in cities nationwide, and featuring appearances by personalities from the entertainment, academic, and political worlds. Beginning with live coverage of activities in the East, NET will then follow the sun across the nation reporting on the magnitude and variety of events of what its youthful sponsors call "a day of illumination." "We will try to provide our own ingredient of illumination with analysis, explanation, and commentary," says Emmy-Award-winning producer Jim Karayn. "We feel a great responsibility to go beyond the rhetoric to examine the realities of what this nation can do about its environmental decay." In Philadelphia, viewers will witness the "Declaration of Inter-dependence." Partaking will be Lewis Mumford, sociologist and author; George Wald, professor of biology at Harvard; Ralph Nader, lawyer and consumer watchdog; Senator Edmund Muskie, (D-ME); and the cast of "Hair," who will perform from a moving garbage truck. Cameras move to Washington for a rally on the Mall, featuring folk singer Pete Seeger. Participants in New York will include Mayor John Lindsay, anthropologist Margaret Mead, Arthur Godfrey, the "Up with People" singers, Dustin Hoffman, and the Baroque Choir who will perform on the steps of St. Patrick's cathedral. From 4 to 6 pm EST, NET's "Earth Day" will tie in with regular children's programming on public television. On "Sesame Street" Gordon introduces children to a "Plezuzmis" and gets the litter-covered street tidied up; King Friday the XIII starts his Clean-Up Campaign on "Mister Rogers" Neighborhood," and "What's New" take viewers to New Jersey's "Great Swamp," where a 12-year-old city boy learns about the balance of nature firsthand. From anchor studios in KCET, Los Angeles' public television station, hosts Maury Green and NET Washington correspondent, David Prowitt, will talk to a number of experts in the field of ecology to probe into what can be done to alleviate the problems. Regular programming will be pre-empted, from 6 to 8:30. During that time, live coverage of events involving student and citizen groups will be interspersed with filmed and taped reports. Playlets about the environment from the Television Theatre of WNDT New York's production of "Foul," by such playwrights as Arthur Kopit and Jules Feiffer, are to be presented. Emanating from the Midwest will be a water pollution scavenger hunt on Lake Michigan. Black ghetto dwellers in St. Louis will also present a play written especially for Earth Day and satirizing the politics of pollution. A short documentary on the internal combustion engine -- source of 60 percent of all air pollution -- in which technologists and member of interested groups will present their viewpoints is also scheduled. Producer of the documentary is John Wicklein. At 8:30 EST, "Earth Day" will present a special edition of "Book Beat," the weekly series originating from WTTW, Chicago. Its host, Robert Cromie, will interview Frank Graham, Jr., author of "Since Silence Spring," an account of the writing and reception of Rachel Carson's book, its immediate consequences, and what has happened in the pesticide industry recently. From 9 to 10:00 pm EST, "Earth Day" will span the East, Midwest, and Far West. There will also be live coverage of the Survival Walk through San Joaquin Valley. This 48-day trek over a 400 mile route dramatizes the extent to which people rely on the land for sustenance. A demonstration against pollution in Minneapolis will also be reported. "Earth Day represents an ideal opportunity for public television," says Don Dixon, NET director of public affairs programming. "We have the interest, we have the air time, and through our affiliates we have the community involvement for this project." (Description adapted from documents in the NET Microfiche)
