Given the pressures of these harsh realities, mankind has no choice but to re-examine its social and economic behaviour and its path of development. Traditional ideas of considering economic growth solely in quantitative terms and the traditional development mode of "polluting first and treating later"are no longer appropriate when considering present and future requirements for development. It is now necessary to find a path for development, wherein considerations of population, economy, society, natural resources, and the environment are coordinated as a whole, so that a path for nonthreatening sustainable development can be found which will meet current needs without compromising the ability of future generations to meet their needs.

在这种严峻形势下，人类不得不重新审视自己的社会经济行为和走过的历程，认识到通过高消耗追求经济数量增长和"先污染，后治理"的传统发展模式已不再适应当今和未来发展的要求，必须努力寻求一条人口、经济、社会、环境和资源相互协调的、既能满足当代人的需求而又不对满足后代人需求的能力构成危害的可持续发展的道路。
