Regarding the article "New Legal Tools Needed to Preserve Earth," Jan. 2: Who will pay for preservation of the environment is a question worth serious discussion. The author points out that the world system is not really a free market and that the market has failed. Yet, there are no economic or legal tools for solving ecological problems. The more the environment is written about, the more pressure the world leaders will have pushing them to make international agreements. Jerrold S. Flemming, Salem, Ore.
