Read the excerpt from "Lessons of Dr. Martin Luther King, Jr." The crop which poses the greatest danger, and the focus of our struggle, is the table grape crop. These pesticides soak the fields, drift with the wind, pollute the water, and are eaten by unwitting consumers.

The poisons are designed to kill, and pose a very real threat to consumers and farm workers alike.
