Fifty years ago, US President John F. Kennedy said that we should to go to the moon not because it was easy, but because it was hard – it tested the best in us. In our generation, sustainable development will be our test, encouraging us to use our creativity and human values to establish a path of sustainable well-being on our crowded and endangered planet.
第三，我们应当设定今后几年的大胆目标——在推广繁荣并改善公众健康的同时拯救地球。50年前，美国总统约翰·F·肯尼迪说我们应该登上月球，以此为目标��非因其轻而易举，而是因其难度极大——能以最严峻的方式对我们构成考验。对我们这一代而言，可持续发展就是我们的考验，它激励我们运用创造力和人文价值在拥挤而濒危的地球上开拓可持续的幸福之路。
