I agree strongly with this. I live in a mainly subsistence-based society, where money is peripheral rather than central to our way of life (basically paying power & phone bills; and ordering a small amount of foreign cargo). You quickly understand that nature takes time to grow and reproduce, and we must look after our world if we desire to survive. Plant something every day, and clear away the weeds or parasites that are impacting what is already growing. Use everything sustainably. Waste nothing. Give more than you take.
