Fishy (Author of the Toe-Sucking Song Book), Even though about 1% of the world's water is fresh water, there is enough for everyone because the water will recycle back to the rivers and lakes that have mostly fresh water. The problem is huge amount of fresh water is now contaminated and largely due to industrialization. The sea-water is no just salt water because the water is needed for marine fishes and corals to thrive. Almost everyday or at least once every other day, we eat fish and they are all salt water. Sea water is more than just salt water which has many other minerals and this is one of an important sources to supply some essential minerals for human consumption....certainly salt is one of them. We just can't live without salt. And how's your Toe-Sucking Book doing....going to get it printed and published soon?
