Unfortunately, addressing the world’s most pressing problems is not as simple as setting up a Web site where foreigners can contribute to social improvements in some other country. So, if you lack the knowledge or standing to involve yourself in another country’s affairs, don’t do it.
不幸的是，解决世界上最紧迫的问题并不像建立一个可以让外国人给别国的社会改善捐钱的网站那么简单。那么，如果你缺少知识或立场加入另一个国家的事务中，就不要这么做。贫困、无知、营养不良、医疗不足几乎到处都存在；但最小努力路径（很有可能同时也是效力最强途径）是从国内开始。
