Read the excerpt from "lessons of dr. martin luther king, jr." the simple act of refusing to buy table grapes laced with pesticides is a powerful statement that the growers understand. economic pressure is the only language the growers speak, and they are beginning to listen. , boycott table grapes. for your safety, for the workers, and for the children, we must act together. this passage shows that one purpose of chavez’s speech is to persuade people to stop buying grapes treated with pesticides. to tell people about the financial troubles of grape growers. to urge people to learn more about ways to protect children. to show people how growers and consumers can work together.

The answer is: to show people how growers and consumers can work together.

Cesar Chavez was a Mexican-American activist in the sixties who worked for justice for laborers and especially farmers in the USA. In the passage above he speaks of growers as landowners who can only speak the language of economics, so that, if consumers stop buying their products, they will obey the economic pressure that this will enforce upon them, and push them to improve the working conditions of its workers. So in this sense, one could say that the passage is talking about growers and consumers working together, but it would be more accurate to say that is a way for consumers to influence growers to obey a higher ethics of production.
