Alberto Pizango Chota saw loggers come to his Indian village in the northern Amazon when he was 7. First they felled the mahogany. Then they returned to cut the cedars. By the time they came back for other hardwoods, there was little left of the forest.

The first animal to crawl onto land from the ocean probably looked a bit like today's salamander, and researchers have wondered how it was able to switch from swimming to walking.

The first animal to crawl onto land from the ocean probably looked a bit like today's salamander, and researchers have wondered how it was able to switch from swimming to walking. Now, European scientists have built a robot with a primitive electric nervous system that they say mimics that change in motion.

By Millar, Heather  It seems like such a tall order: Proactively plan human activities so that they mesh with the natural environment. Try to approach nature as a system, even though we don't now, and may never, fully understand all of its' complexities.

Hard to believe, but the chair lift wasn't the main way of getting to the top of a mountain for skiers during the World War II era. Some 70 years ago, there was the shovel handle, rope tow, j-bar, and even the skimobile lift.
