Living in the Past

“Two types of choices seem to me to have been crucial in tipping the outcomes [of the various societies' histories] towards success or failure: long-term planning and willingness to reconsider core values. On reflection we can also recognize the crucial role of these same two choices for the outcomes of our individual lives.”
- Collapse: How Societies Choose to Fail or Succeed by Jared Diamond Speaking of changing our ecosystems, Time Magazine recently had a cover article about foreign species invading the ecosystem of the U.S.. The more we “globalize,” the more risk we run of importing diseases, pests, and new species of animals which might cause problems for our native species and for us. Like the historical events which now oblige gardeners in Australia to have to deal with the huge population of imported rabbits, many of these “aliens” multiply easily in new lands. Some even some start killing off other species which have no natural defenses against them. The huge population of Burmese pythons in the Florida everglades is a classic example. But these sorts of importations have happened throughout history, and the ecosystems change. Environments are changing ever more quickly now because of global warming. Plants and animals die off in areas that were once hospitable to them, and begin to thrive in new areas. The question for us is: will we continue to cling to our old ways of doing things, like creating energy, food, housing, and consumables, until we exhaust the supply of traditional raw materials? Jared Diamond writes about the Viking colony that settled on the coast of Greenland between the tenth and fifteenth centuries and proceeded to do just that. They kept going for a long time, maybe about five hundred years. For some, it probably seemed as if they would be successful forever, because they were employing the methods that had always worked well before. But eventually, it all collapsed. In their case, it seems that supply ships from Norway had helped them to keep going, and when those stopped coming it might have been the beginning of the end. We don’t have supply ships to help us cling to a past era, though. Perhaps the only way to greet our changing world is not to expend increasingly more energy to fight it, but to adapt to it. In Columbia, South America, there is a colony that has been taking on the challenge of doing exactly that.
