...point right now. Is the destruction of one football-field's worth of forest every second enough to make the frog react and jump out of the pan? What will it take? If, as in a science-fiction movie, we had a giant invader from space clomping across the rain forests of the world with football field-size feet -- going boom, boom, boom every second -- would we react? That's essentially what is going on right...
Before Brazil's great land rush, the emerald rain forests of Rondonia state were an unspoiled showcase for the diversity of life. In this lush territory south of the Amazon, there was hardly a break in the canopy of 200-ft.-tall trees, and virtually every acre was alive with the cacophony of all kinds of insects, birds and monkeys. Then, beginning in the 1970s, came the swarms of settlers, slashing and burning huge swaths through the forest to create roads, towns and fields. They came to enjoy a promised land, but they have merely produced a network of devastation...
Nearly every habitat is at risk. Forests in the northern hemisphere have fallen to lumbering, development and acid rain. Marine ecosystems around the world are threatened by pollution, overfishing and coastal development. It is in the tropics, though, that the battle to preserve what scientists call biodiversity will be won or lost. Tropical forests cover only 7% of the earth's surface, but they house between 50% and 80% of the planet's species...
...should people in developed countries care about the survival of tropical species never seen outside a rain forest? Yes, they should. Variety is the spice of life, goes the saying. Biologists would go further and argue that variety is the very stuff of life. Life needs diversity because of the interdependencies that link flora and fauna, and because variation within species allows them to adapt to environmental challenges. But even as the world's human population explodes, other life is ebbing from the planet. Humanity is making a risky wager -- that it does not need the great variety of earth...
...today contain ingredients originally derived from wild plants. Hidden anonymously in clumps of vegetation about to be bulldozed or burned might be plants with cures for still unconquered diseases. "I know of three plants with the potential to , treat AIDS," said Janzen. "One grows in an Australian rain forest, one in Panama and one in Costa Rica...
