From John Brinkman, Clean Water by Karen Barss was a great book. It took an in depth look on how the human race is polluting and overusing its fresh water supply. The AP Environmental class prepared me very well for this book. I had already heard most of the terms used in “Clean Water” and this just took a real world look at the problems. I never knew how bad the problem of salinization was in the world. It said that up to one half of all the farming land in India could be depleted by salinization by 2000. That was another interesting aspect of the book. It was written in 1992, so most of the theories it had presented had come to pass in some form or another. It mentioned that the aquifers unless given adequate time to refill would vanish. This is happening all over the world at a prodigious rate. The book was great at showing the cause and effect that humans are having on the supply of clean water. In the 1980’s the russians wanted to build a cotton industry near its deepest lake. To do this they diverted 50 percent of the water that went into the lake. This provided more than enough water for the industry of cotton. It also caused the lake to shrink by about sixty feet. This exposed hard unfarmable land that was full of minerals. The diversion of the river did give enough water to the cotton fields but because the lake bottom was exposed minerals are being carried in great supply to the cotton causing salinization. Twenty percent of the usable land for the crop is now unusable for farming because of high levels of mineral exposure. “Clean Water” by Karen Barss was a great book and taught me much about the importance of freshwater and our need to conserve it.
