An ecological cycle In the design of his own residence / workplace, Toshiharu Naka created a small ecological cycle. Rows of green planters in front of the wall protect the house from the sun and help cool it in summer. Rainwater is collected via catch-basins from the roof, and used to water the planters. In the water buckets is a micro-cycle — fish live in the buckets, eating mosquitos from the planters, eliminating the need for pesticides. Toshiharu Naka, Two Cycles Turn them into cycles
