When Kenyan environmentalist and Nobel Peace Prize recipient Wangari Maathai visited Japan in 2005, she encountered a word that has no direct English translation: mottainai. Although the meaning of term has evolved throughout Japanese history, it is used today to indicate a sense of regret over the waste of anything useful. Maathai has since promoted the use of the word to raise awareness about conservation issues. What English expression is closest in meaning to that of mottainai? Discuss
