S80.00/$110.00 hbk, %29.95/$44.95 pbk (1149 pages) ISBN 0 5215640341816 his is a formidable book - intimidating and authorative - the iist of contributors alone spans 40 pages. A comprehensive team of experts addresses each of the key problems of global biodiversity assessement from a number of perspectives: ecological, t?xonomic, economic and philosophical. To any ecologist or conservation biologist it provides a comprehensive introduction to what is arguably the world’s most significant problem. Furthermore, it is excellent value for money. Yet, in many respects we are lucky that it is available to us; for if the US or British governments realistically considered environmental problems as a threat to human welfare and international security, then it is likely that this would be a classified document. So the books editors seem to have a second source of motivation: to rectify the lack of interest in biodiversity that characterizes many of the world’s governments. In this the book also achieves a high degree of success by assembling a mass of evidence about biodiversity and its role in maintaining the health of the planet. However, Bworry that elegantly explaining the multitude of problems that are likely to arise if the present loss of biodiversity continues will b;: insufficient to persuade governments to change their policies. Instead ecologists, conservation biologists, and environmental policy analysts need to go on the offensh e and attack other governnt patment policies that terns of short-ter nomic planning. In part ant to directly compare environmental problems with the peculiar fascination of the dominant econotnic countries with maintaining safe access to the world’s oil supplies and ensuring a healthy market for arms sates. These issues continue to dominate the foreign policy of many countrtes and tend to keep environmental issues stewing on thetr governments’ back-burners. Unfortunately, as this volume shows, short-term militaryjingoistic, vote-ca easy solution to the
e~v~ronmentai change and more traditional and readily focused threats a little further,
before considering the book in more detail. A few months ago the US fired around 40 Tomahawk cruise missiles at key militaly installations in southern Iraq. At around a million dollars per missile, that weighs in at around 40 million doilars. or an amount roughly equivalent to one-third of the total annual cost to the UStax payer of funding the Endangered Species Act. This four months of spending to maintain biodiversity is the equivalent to around an hour’s spending in a normal Pentagon X-hour period. Does Iraq present a thousand-fold greater threat to the long-term health of the USA’s citizens and its economy than a healthy environment? It’s not an easy calculation, as we’re cornparing different ethical currencies, but if we were to translate some aspect of these currencies into electoral votes, or lives lost. then I can’t help thinking that this difference in funding rates shows a tragic disparity in the government’s, and the public’s, perception of the factors that pose a long-term threat to security, peace and human health. We can extend this comparison between military success and environmental success one stage further and compare the areas of land captured, defended and protected for the future by these two potential cornpetitors for government funds. A variety of sources in the Global Biodiversity Assessment suggest we have set asfde nearly 10000 protected areas as National Parks; most of these Y48mi e been identified and set asid 30 years. This is area of the Indian roughly equi subcontinent. I can think of no military operation over the same historical time period that has been as successfui ir?ensuring longterm peace, or in aiding t democracy. For example, if we examine the US military record over a similar period, we can plot a simple graph of the sue attempts to restore, or maintain against the size of the count action took place (Haiti, Kuwait, Panama, Lebanon, Iraq, Korea, Vietnam, Somalia). If we score 1for success, 6 for a loss and 0.5 for no clear resuit, i! simple logistic regression suggests that the Pentagon has less than a 50% chance of restoring or rnaint~n~~g democracy in a country much bigger than Panama. All this suggests that we are not ounts of only spending disproportionate money on military attempts to maintain global stability, but that ?his money is not spent particularty effecrively. If any USsports team bad a less than 5JX chance of beating Somalia, Vietnam 01’ Lebanon, someone would certainly take ;: very bard ‘tookat the coachirag staff and the training methods. ~~rt~~er~ore, B’m sute we’d find a si disparity in rates of military an mental spending if we examined the UK,and a whole variety of other countries.

concern for the e~v~ro~me~t rnav be for the long-term health of the planet. U*~~ort~~ate~y, the education syllabuses of most countries underemphasize the role that the environment has @ifed in human history and in st~rn~~at~~g and constraining human innovation. Consequently, the v&t majority of people, as weEi as most politicians and economists, underestimate our dependence upon other species. This book clearly shows that the vast majority of people are entirely dependent upon natural resources for underpriced but irreplaceable commodities, such as breathable air, drinkable water, functional decomposers and soil in which to grow food crops. I think it is likely that the future of democracy, and much of the rest of history, will depend on how we manage ,and distribute access to these natural commodities. At present we have completed expioring the Earth’s surface for readily accessible and easily removed commodities and are exploiting these at rates t&at far exceed their replacement rates. Access to these resources is inequitable and is likely to become increasingly so. Biological exploration has proceeded in two other directions: on the microscopic front we have a comprehensive understanding at the molecular level of the key life-processes of a handful of organisms; although a significant proportion of this f~octiona~ understanding will extend to ail species, we do not know, to within a range of S-30 million, how many other species currently exist on the planet. ~~fo~~~ate~y, extrapolation from the few well-understood species to the many unstudied species provides an incomplete picture of how in&actions between species determine the efficient and continuing function of the ecosystems that provide the planet’s life support services. This book vides an excellent introduction to the entific complexities of addressing this key problem in planet management. It also describes Row the world’s economy ignores, or completely undervalues, these services. Furthermore, it subtly, but forcefully, makes the point that ecology and conservation deal with more complex scientific and ethical problems than occur in the more mundane, but much vaunted, rocket sciences. The book also provides sensible suggestions on how to modify environmental and economic policies so as to help rrducc act of humans on the environment. These crucial messages are delivered in measured and balanced academic tones. U~for~~~ate~y,this means that the hook fails to drive home the point that if we continue to ignore the current assault and pillage on the planet’s life s~qq~ort system then it is likely that we will have to rely on overexpensive, and woe‘urly inefficient military means of ~aintai~in~~ an increasingly inequitable access to the vitai rcsource~ that sustain life on Earth.
