A person who undertakes to grow a garden at home, by practices that will preserve rather than exploit the economy of the soil, has his mind precisely against what is wrong with us. . . . What I am saying is that if we apply our minds directly and competently to the needs of the earth, then we will have begun to make fundamental and necessary changes in our minds. We will begin to understand and to mistrust and to change our wasteful economy, which markets not just the produce of the earth, but also the earth's ability to produce.
