Article 18165remained hostile and many indigenous combatants have merely discarded their uniforms and hiddentheir weapons, almost certainly with the intention of using them at the first opportunity. Diplomaticrelationships of long standing have been replaced with suspicion and lack of trust. TheUnited Nations has, temporarily, ceased to function as intended. Most of humankind is still feelingdistress, and the end of this emotion is not in sight — hardly an appropriate condition for embarkingon a cooperative program to globalize sustainability, which requires implementation of euthenics(i.e. science concerned with bettering the condition of human beings through improvement oftheir environment).The quest for sustainable use of the planet will be stressful because the shift from unsustainableto sustainable practices will require major, initially unpleasant, changes in both individual and societalbehaviour. War itself is an unsustainable practice if humankind intends to leave a habitableplanet for posterity. Humankind is already pushing the limits of environmental carrying capacity infood, water, fossil fuels, toxic chemical substances, radioactive wastes with a long half-life, andrate of climate change. For example, world production of petroleum will soon begin to decline (e.g.Deffeyes, 2001; Duncan, 2001).The activities of humankind have placed nitrogen, potassium, and phosphates into the environmentat a rate greater than that of natural systems. These chemicals degrade all types of waterecosystems, e.g. there is a ‘dead zone’ in the Gulf of Mexico and brown slime in the Adriatic. Theconsequences of these activities are uncertain, but, at present, they cannot be stopped becausewithout commercial fertilizers billions of humans would die (e.g. Smil, 1991). The era of rising irrigationhas ended (Postel, 1999), and even water rich areas of the United States have had to beginimporting water by truck for growing populations (Grant, 2003). Such environmental crises couldlead to resource wars if the human population continues to grow. However, if the human populationwas stabilized at present levels, or reduced, the funds that are being used to reduce thesecrises temporarily could be used to develop long-term sustainable practices. This more desirablestate requires reexamination of war and growth, both demographic and economic, and the ethicalrelationships within human society and with the 30+ million other species with which humans sharethe planet.A FUTURE WITHOUT HUMANSOn May 18, 2003, the television channel Discovery aired the program ‘Future is Wild.’ Scientistsenvisioned a future world in which humans are extinct and bizarre creatures inhabit the world.Many people would dismiss a world without humans as science fiction or fantasy. ‘Future is Wild’illustrated climatic and geological changes that, if even partially accurate, will drive most extantspecies, probably including Homo sapiens, to extinction over the next 10 to 100 million years. Ifsustainable use of the planet truly means working toward human use of the planet indefinitely,humankind needs to demonstrate the capability of living sustainably under the present comparativelybenign conditions. If this goal is not possible, sustainability is a denial of reality and a moresuitable word to describe human activities should be selected.One obvious beginning point of working toward sustainability is with energy (defined as thecapacity to do work). Heniberg (2003) argues that global oil output will peak in 3–12 years. If anaggressive shift toward new energy sources, such as wind, solar, or fuel cells in the mix, is notachieved in the 3–12 year time period, there will be severe, even grim, consequences, such as economiccollapse, resource wars, famine, disease, and despotism. If humankind reduces energy consumption,the transition period can be lengthened, but the basic problem must be addressed.
