Experts in evolution determined decades ago that the human species arose in Africa. Fossil bones found there are far more ancient than human remains found anywhere else. But when and why our ancestors first ventured away from the mother continent to take up residence in other parts of the world have been matters of debate. The conventional wisdom had long held that Homo erectus, the immediate ancestor of Homo sapiens, made the exodus about 1 million years ago, after developing relatively sophisticated stone tools that enabled him to gather food more efficiently during his wanderings...
...results of our "heinous interference" are demonstrated by more than a simple fluctuation in daily temperature. Chunks of ice are breaking off the poles, leading to a rise in sea level. The burning of fossil fuels spews great pollution, making the air in some cities almost unbreathable. The current rate of species loss is unparalleled, except for the period after the meteor hit the Earth, killing off the dinosaurs. No one is calling Gore the savior of the Earth, but we will be calling ourselves fools if we continue to believe that nothing is going...
...Absent from Kabala's account the possible devastating consequences should warming theory be true: floods, disease, famine, severe economic dislocation and rapid species loss. Even most fossil fuel companies understand the necessity of moving toward alternative fuels and renewable energies. Clearly they, unlike Kabala, understand the risk is not worth taking...
That was true not just for Africa. The fossil record tells the same story everywhere. Most of life's experiments have ended in extinction. It is estimated that more than 95% of the species that have existed over the past 600 million years are gone...
...source of virtually limitless profit. The idea is to retrofit our farms, factories, shops, houses, offices and everything inside them. The economic activity generated would be enormous. Better yet, it would be labor intensive; investments in energy efficiency yield two to 10 times more jobs than investments in fossil fuel and nuclear power. In a world where 1 billion people lack gainful employment, creating jobs is essential to fighting the poverty that retards environmental progress...
