Representatives of 172 nations agreed to work toward the sustainable development of the planet, although most of the agreements were not legally binding. Sustainable development is the growth of population, industry, and agriculture in a way that will allow the present generation to meet its own needs without damaging those of future generations. Two binding declarationsto minimize global climate change (see global warming) and to stem the depletion of the worlds inventory of biological diversity were signed by more than 150 countries at the conference, with others expected to sign later.
