> Water is a renewable resource

A lot of water used for agriculture in the US is "fossil water" from aquifers that takes millions of years to replenish. The oceans are a limitless supply of water, but like the HB process, require energy to convert to a useful form.

Moreover, in many instances, the conversion to a useful form is short-changed, leaving salts in the water which results in long-term problems --- look at agriculture around Lake Baikal for an example.
