Conservation and the humane movement are Siamese twins. They are inseparable. I beg you to keep this in mind, to think about this, because there is an explosion coming in the conservation movement. Senator Gaylord Nelson of Wisconsin, a great conservationist and humanitarian, is leading the fight now for a teach-in that is going to take place in colleges across this country early next year--early in 1970. Students and teachers are going to sit and talk about nothing but ecology and a crash program of awareness. We are heading for national and international catastrophe and it will soon be on us. These forces are bringing to the foreground the absolute necessity for conservation. The humanitarian movement can gain nothing but strength from the association. Do not be prejudiced against it.
