This chapter discusses the basic ideas and principles that may give coherence and direction to the evolving law on the management of hazardous substances at the international level. A brief account of private efforts such as by Pesticide Action Network and the Agricultural Chemicals Dialogue group, etc. for the safe use of pesticides and other chemicals, also features in this chapter. In May 2010, the Sixty-third World Health Assembly in a resolution recognized that inappropriate promotion of breast milk substitutes and some commercial foods for infants and young children had been undermining progress in optimal infant and young child feeding. Therefore, it requested member states to put an end to “inappropriate promotion of food for infants and young children.” A participating state must ensure that its pharmaceutical industry utilizes appropriate testing measures and manufacturing practices. In order to achieve environmentally sound management of hazardous wastes, state parties must come closer and provide the necessary information on multilateral and bilateral basis.
