Last Sunday was marked by an orgy of celebrations of Earth Day, the worldwide annual event intended to "to spark a revolution against environmental abuse."

Even the Bush administration had an Earth Day website, which stated, "< a href="http://earthday.gov/">Earth Day and every day is a time to act to protect our planet".

Watching the media coverage, you'd think that the earth was in imminent danger -- that human life itself was on the verge of extinction. Technology is fingered as the perp.

Nothing could be further from the truth.

John Semmens of Arizona's Laissez Faire Institute points out that Earth Day misses an important point. In the April issue of The Freeman magazine, Semmens says the environmental movement overlooks how hospitable the earth has become -- thanks to technology. "The environmental alarmists have it backwards. If anything imperils the earth it is ignorant obstruction of science and progress. ... That technology provides the best option for serving human wants and conserving the environment should be evident in the progress made in environmental improvement in the United States. Virtually every measure shows that pollution is headed downward and that nature is making a comeback." (Carbon dioxide excepted, if it is really a pollutant.)

Semmens describes his visit to historic Lexington and Concord in Massachusetts, an area "lush with trees and greenery." It wasn't always that way. In 1775, the land was cleared so it could be farmed. Today, technology makes farmers so efficient that only a fraction of the land is needed to produce much more food. As a result, "Massachusetts farmland has been allowed to revert back to forest."

Human ingenuity and technology not only raised living standards, but also restored environmental amenities. How about a day to celebrate that?

Yet, Semmens writes, the environmental movement is skeptical about technology and is attracted to three dubious principles: sustainable development, the precautionary principle, and stakeholder participation.

The point of sustainable development, Semmens says, "is to minimize the use of nonrenewable natural resources so there will be more left for future generations." Sounds sensible -- who is for "unsustainable" development? Continued...
