Economic prosperity and environmental improvement are not mutually exclusive. Industry has made impressive gains in boosting productivity while improving environmental protection. The timber industry is a prime example. Despite this, net tree growth has exceeded harvest every year. In 1995 the U.S. planted 2.4 million acres of trees, up 1 million acres from 1970.
Modern jets are more environmentally friendly.
The Boeing 777 has nearly the same passenger capacity and range capability as the 747, but burns one-third less fuel. These improvements make it harder to convince the public that there are serious environmental ills. Take the alleged threat posed by man-made global warming, the cause celebre of modern environmentalism. Environmentalists insist that most scientists agree that human activities are causing significant global warming. The signers include 2,100 climatologists, meteorologists and environmental scientists.
