对水源管理者来说，只有在水通过物理蒸发变成空气的一部分，或者被植物吸收并且转变为水蒸气形式(蒸腾作用)的时候，才被消耗了。
For a water manager, the only time water is consumed is when it evaporates into the air or is soaked up by plants and then turned into water vapor (transpiration).
没有这个突破，种更多的粮食便不可避免地意味着失去更多的水，因为每一棵额外的作物在光合作用过程中都会将水蒸气带入空气当中。
Without such a breakthrough, growing more crops inevitably means losing more water, since each extra plant transpires water vapour into the atmosphere during photosynthesis.
