Life's Matrix by Philip Ball

Water is a chemical essential to human life and culture, and it is possibly the oddest common substance. Physicist and science writer Philip Ball describes the nature of water, both scientific and cultural, in Life’s Matrix (originally published in the United Kingdom as H2O: A Biography of Water).

Ball begins at the very beginning—the big bang. Hydrogen, the simplest atom and most abundant element in the universe, appeared early in the universe. Oxygen is forged in stars and has become the third most abundant element. There is water in space. Ice seems to be common in the far reaches of the solar system. It has been found on the moon and stars and a few molecules appear in the cooler spots on the sun.

We have found no worlds yet that have as much liquid water as ours. The water cycle has shaped Earth. Our weather comes largely from the interplay of water and energy. Even the water locked up in the ice of our poles and glaciers shape the land, influence the weather, and affect the movement of heat, water and salt in ocean currents.

Ball tackles all phases of water, including a few exotic forms that only occur in extreme conditions created in laboratories. That water exists as vapor, liquid, and solid within the fairly narrow range of temperatures that are common on Earth make it unique. This is just one of its unusual properties. The structure of the water molecule is described in the book along with the physics that explain its behavior, to the degree that such things are even known.

Our understanding of water as a compound of hydrogen and oxygen is a relatively recent thing. For a long time, water was thought of as an irreducible element. This makes sense on some level. Water is essential to life as we know it. It is irreplaceable. From the perspective of living creatures, and in almost every culture, water is a fundamental material.

In the final chapter, Ball moves away from the hard sciences to culture, economics and policy. Water of the quality needed for drinking, and even the lesser quality needed for other things, is scarce and unevenly distributed on the planet. To take a serious look at water is to be drawn to issues of health and wealth. Growing population and changing climate will put increased demands on the available fresh water, and we need to consider how we are going to manage it. Ball takes a look at some of the hot spots.

The book is intended for a broad audience. I think it is probably more accessible to someone with some education in the sciences, especially chemistry or physics, but someone had a high-school level class in these subjects they should be able to follow along.

In addition, the book is 16 years old, so necessarily out of date in some respects. I suspect that much of the physics, chemistry and biology described is still sound. Similarly, there is unlikely to be discoveries in history that would seriously outdate the book, even in the interesting section on dead ends and “pathology” in water science.

The Big Thirst by Charles Fishman

More than 1 billion people do not have access to clean drinking waterAustralia has suffered a decade-long, continent-wide drought.  Even seemingly water rich places, like Atlanta, Georgia, can’t get enough water.  Many are talking of a global water crisis.  Except, as Charles Fishman aptly states it in The Big Thirst, “There is no global water crisis, there are a thousand water crises, each distinct.”

I think the story of Atlanta and Lake Lanier, as told recounted by Fishman, is especially instructive.  Lake Lanier on the Chatahoochee River is the source of 75 percent of the water used by Atlanta, 5 million gallons a day.  A drought in 2007-2008 brought the level of the lake dangerously low, prompting downstream states to sue over the amount of water Atlanta was taking.  The federal court declared that Atlanta had been illegally receiving water from the lake and had to find another source.  Atlanta has a lot of resources, barely tapped conservation efforts, reuse, and alternative supplies, but with a lack of political will, leadership, and vision, it leaders threw up their hands in impotent defiance of the court and whined they must have Lake Lanier water.  When the lake was built, Atlanta passed on paying for a piece of it thinking it would never be needed, and now they think they can’t live without it.


Part of the point Fishman makes it that water crises are more often than not political crises.  There is a lack of political will and sense of necessity, even though the problems can be plain and the solutions within reach.  The Big Thirst includes examples from around the world (the United States, India, and especially Australia) where people are facing water problems.  Happily, many of them have taken a more realistic and reasonable approach than Atlanta.

Fishman is going for something deeper, though.  Our political and economic stumbling in the area of water management stems for our cultural relationship with water.  It is obviously necessary for life.  We also consider it beautiful, it is part of our landscape, and in some places it has important religious significance.  Even so, we have difficulty understanding the value of water, comparing one use to another, assigning responsibility for its distribution and quality, acknowledging the infrastructure needed to have water when and where it is needed.  It the West, where for the last century we have enjoyed incredible access to abundant water, we hardly ever think about water unless we have some professional connection to it.

We can’t continue to be mindless of water.  The systems of water abundance we built in the last century aren’t sustainable without major ongoing investment.  In light of climate change, they may be altogether unsustainable.  Even without climate change, much of our water policy dates to a time of unusual water abundance.

Fishman encourages water mindfulness.  We need to reconnect to water.  In part, this reconnecting means understanding what it means to have water in our homes and in our streams.  It is also connecting to how critical water is to food, energy, commerce, health, and almost every aspect of life.  Our decisions about water need to be rooted in reality.

Water by Marq de Villiers

I originally posted this review at Infrastructure Watch, where I write about civil infrastructure, the environment and other matters of technology.

de Villiers, Marq. Water: The Fate of Our Most Precious Resource. 1999. Boston: Houghton Mifflin, 2000.

Marq de Villiers serves as a guide on a tour of water problems, conflicts and occasional solutions around the world. Though he is not an alarmist, his book seems to indicate that the problems have so far greatly outpaced the solutions.

There are several aspects of water problems and conflicts that de Villiers considers: natural, technological and political. In each area, he provides specific examples of water in or nearing crisis.

The natural distribution of fresh water in the world is uneven. That may be the fundamental aspect of water problems: even where it’s seemingly abundant, it doesn’t occur where and when people want it to make use of it. In parts of the world, this is a dire situation.

The technological solutions people have applied to correct this distribution have resulted in some amazing works of engineering since early in human history. It has also had many unintended consequences. Irrigation that made marginal land productive has made some of that land useless, even desert, through increased salinity. Dams, drainage and transfers have created ill effects in regional climates. Water mining, pollution and other human activity are also threatening the quantity and quality of water even in developed nations. There is hope in the technological area in that much of this harm may be reversible and the human ingenuity that created these technologies might also create sustainable solutions to our water needs.

Political considerations are very important to water issues, particularly when considering the possibility of conflict, even outright war, because of water scarcity. The Middle East and North Africa come to mind as hot spots where water is a critical issue; de Villiers enlightens both the current situation and history of these regions. Though mistrust runs deep between the nations in this region, even seemingly friendly ones, there is hope for solutions to their water problems. North America has its water problems to, and the problems on the Colorado River are surprisingly similar to those on the Nile. The differences in water availability in the United States, Mexico and Canada also makes for interesting relations between these close and usually friendly neighbors. China may present the largest political problems related to water and it’s food production and population that threatens to push it into crisis.

The book closes with four general strategies for dealing with the world’s water problems. First, get more water by either bringing it in from elsewhere or making it (i.e. desalination). Next is conservation and pricing to reduce demand and encourage using water in the most valuable ways. Third is population control; de Villiers seems relieved that world populations have been growing more slowly without major intervention. Finally, you can steal water from others. Since 40 percent people worldwide live in watersheds that cross national boundaries, it becomes a complicated matter of who has what right to the water and this is a potential source of water conflict, though not insurmountable.

P.S., here is a little something extra for those of you interested in China, especially the probably fictional Emperor Yu the Engineer.

The Boom by Russell Gold


The great expansion of natural gas wells that was brought about by new technologiesdirectional drilling and hydraulic fracturing (fracking)—in the last few decades has meant that a lot more people are physically closer to the energy industry. In 2013, more than 15 million Americans lived within a mile of a fracked well. Journalist Russell Gold has a personal connection to this change in the energy landscape; his parents own property in Pennsylvania that they leased out for natural gas drilling.

In his book, The Boom, Gold explores the history of the oil and gas industry, and the development of key technologies, that led to the present abundance of natural gas. This interesting and long history energy exploration and development has attracted colorful characters.

The natural gas boom has also created opportunities and challenges. For one thing, fracked wells can produce a lot more natural gas and get it from rock formations that were previously considered too impermeable to economically give up the gas they stored. Now we get gas from these rocks and the natural gas supply that once seemed limited now seems enourmous, and prices for natural gas have dropped in response.

In addition, natural gas produces less carbon dioxide and other pollutants than burning of other fuels such as coal. Even though the U.S. has not participated in international carbon-control protocols, the growth of natural gas as a fuel, replacing other energy sources, has made the U.S. one of the few countries to come close to meeting goals for carbon reduction.

Even so, natural gas is a fossil fuel that carries some of the problems of its cousins. For instance, natural gas is mostly methane, which is a powerful greenhouse gas. Releases of methane reduce some of the gains made by switching from coal or other less clean-burning fuels to gas. Cheap gas also makes alternative energy sources such as solar or wind less economically attractive, which may delay the development of these resources.

Gold seems to balance these issues. Natural gas is a superior fuel to coal from the perspective of air quality and climate change. It is probably also necessary to use natural gas as a bridge to solar and wind as a way to provide stability as these naturally variable energy sources, along with the energy storage needed to make them truly feasible, are improved. Other problems with gas, such as potential threats to water quality, can be mitigated with existing technology, better rules and careful management.
