The Population Action International study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water of agriculture.

　　人口行动组织的研究报告为世界的水短缺问题提出了几个解决的办法。第一，找到多用途的用水方法。第二，教育人们不要浪费水资源。第三就是少用农业水。

　　The report also says long-term solutions to the water problem must include controls on population growth. It says countries cannot provide clean water unless they slow population growth by limiting the number of children people have.

　　报告同时表明，控制人口增长是长远解决水缺乏问题不可缺少的措施之一。它说除非各国能通过限制生育来降低人口的增长，否则它们不可能提供干净的水。
