Japan likes to think of itself as a nation at the forefront of environmental action, but it still has a lot to learn from other countries. On
"Honto no Eco wo Kangaeru Chikyu Ryoko" ("Global Journey In Search of Real Ecology"; Nihon TV, Fri., 9 p.m.), Masaki Aiba of the boy band Arashi and other celebrity reporters travel the world to find answers about the environment.
Aiba goes to Bhutan, a country whose material wealth isn't very high but whose spiritual richness is envied worldwide. In surveys, 97 percent of the citizens declare themselves "happy." Aiba learns how the average Bhutanese lives in harmony with nature. He is also granted an exclusive interview with Bhutan's prime minister.
