A Word

From Our National Director

“The Izaak Walton League strategic plan… is to make conservation a way of life for every citizen. We (have) failed, in spite of our heroes, in spite of the Clean Water Act, the Clean Air Act, the Endangered Species Act. We have not reached every day citizens. We have done the reverse in many ways. All of our success in the ’80s, in some ways, has made us a little arrogant, too piped into big government, too piped into top-down. I think I’m right that we start with our neighbors. We don’t start with the U.N. We don’t start with U.S. Senate. If all politics are local, then we go back to the old ways — from pre- and post-World War II. We go to the PTA. We talk to our neighbors and try to understand them.”
