An idea which Kawamori presents, although in a problematic and sometimes contradictory form, is natural farming. Not to be confused with the mere absence of chemicals that is often meant by "organic farming", natural farming involves letting nature grow as it will, not removing weeds or bugs, or using any fertilizer. The old man Juna encounters in episode four explains the need for this return to nature in order to sustain life in the long term, a sentiment matured by the creator during his Asian journeys (not only India, but Nepal and other countries as well).
