Odd as I am sure it will appear to some, I can think of no better form of personal involvement in the cure of the environment than that of gardening.

He is producing something to eat, which makes him somewhat independent of the grocery business, but he is also enlarging, for himself, the meaning of food and the pleasure of eating.
