“The impious trees are useless jungles only, and they can only be used to supply fuels. In the modern civilization such impious trees are planted on the sides of roads. Human energy should be properly utilized in developing the finer senses for spiritual understanding, in which lies the solution of life. Fruits, flowers, beautiful gardens, parks and reservoirs of water with ducks and swans playing in the midst of lotus flowers, and cows giving sufficient milk and butter are essential for developing the finer tissues of the human body.” (Shrila Prabhupada, Shrimad Bhagavatam, 1.11.12 Purport)
