6 Species An Hour Doomed To Extinction

"Rats, weeds, cockroaches and other hardy, ubiquitous "tramp" species may never inherit the earth. But some scientists say they could make a run for global ascendancy if humans, as many biologists fear, precipitate a mass annihilation of less adaptable creatures. In this scenario, the actions of an exploding human population are sundering the ecological webs that support life by setting off a worldwide wave of extinctions comparable to the one in which the dinosaurs perished some 65 million years ago." It is "estimated that 50,000 species a year, or about six every hour, are being doomed to eventual extinction."
