Second, we must recognize the powerful new tools and technologies that we have at hand. Using advanced information technologies – computers, satellite mapping, image processing, expert systems, and more – we now have the means to grow more food with less environmental damage; improve public health for rich and poor alike; distribute more electricity with lower greenhouse-gas emissions; and make our cities more livable and healthier, even as urbanization raises their populations by billions in the coming decades.
其次，必须意识到我们掌握着可供利用的高效的新工具和新技术。运用计算机、卫星定位、图像处理、专家系统和更多的先进信息技术，我们已经掌握了在减少环境损害的同时生产更多粮食、改善贫富群体公共健康、在降低温室气体排放的同时输送更多电力、以及即使今后几十年城市人口因城镇化增加数十亿，也能使我们的城市更加健康宜居的全新方法。
