There was also almost no environmental law taught in any law school. I only ran into in all of 1969 and 1970 just one environmental reporter in the whole country. But now every paper has somebody that covers environmental issues. Now you turn on the TV and find an environmental program or two every single day. That makes a difference.
People are much more sophisticated and much more concerned today.
That, in general, is the biggest development to come out of Earth Day. Air pollution and water pollution were the obvious ones. I drove down to Washington sometime after the second World War, about 1947 or 1948, and you could see Pittsburgh pollution from 100 or 200 miles away. There was a huge, ugly, yellow cloud. People started wearing gas masks in Los Angeles and putting out smog alerts saying that little kids shouldn't be out playing on certain days.
