An unfolding technology has increased our economic strength and added to the convenience of our lives. But that same technology-we know now-carries danger with it. From the great smoke stacks of industry and from the exhausts of motors and machines, 130 million tons of soot, carbon and grime settle over the people and shroud the Nation's cities each year. From towns, factories, and stockyards, wastes pollute our rivers and streams, endangering the waters we drink and use.

No nation in the world has had greater fortune than mine in sharing a continent with the people and the nation of Canada.

As we maintain the vigil of peace, we must remember that justice is a vigil, too - a vigil we must keep in our own streets and schools and among the lives of all our people - so that those who died here on their native soil shall not have died in vain.

This generation has altered the composition of the atmosphere on a global scale through radioactive materials and a steady increase in carbon dioxide from the burning of fossil fuels. Entire regional airsheds, crop plant environments, and river basins are heavy with noxious materials. Motor vehicles and home heating plants, municipal dumps and factories continually hurl pollutants into the air we breathe. Each day almost 50,000 tons of unpleasant, and sometimes poisonous, sulfur dioxide are added to the atmosphere, and our automobiles produce almost 300,000 tons of other pollutants.

I shall never forget the faces of the boys and the girls in that little Welhausen Mexican School, and I remember even yet the pain of realizing and knowing then that college was closed to practically every one of those children because they were too poor. And I think it was then that I made up my mind that this nation could never rest while the door to knowledge remained closed to any American.

The fifth freedom is freedom from ignorance.
