Generally speaking the more developed countries of North America, Europe and Russia will not see a serious threat to water supply by the year 2025, not only because of their relative wealth, but more importantly their populations will be better aligned with available water resources.
一般說來，北美與歐洲等國家在2025年時並無迫切的水資源危機，不只是因為富有，也是因為他們的人口數並沒有那麼擁擠，因此可均分到適當的水資源。
