Chris was not surprised as they were the most important problems those days.
Frank thought that many people understood they should protect the environment.
Chris was not quite sure if they really understood because facories dumped wastes into rivers, air pollution was getting worse, too.
Frank agreed & added that more & more people fought agaisnt nuclear tests, nuclear weapons & other things.
