"Today, Wilson presides over a staff of 150 in Maynard's landmark Clock Tower Place. The 19th-century wool mill is now a clearing house for environmental research projects conducted worldwide. Earthwatch receives some 300 applications from scientists looking for research fund s and volunteers. The organization recruits people willing to pay for the privilege of working as a research assistant in the field. Their payments -- about $2,000 for an average two-week trip -- help cover the costs of the research.
Through its offices in the United States, England, Japan, and Australia, Earthwatch annually recruits 4,000 volunteers to take part in 140 projects in 55 countries. They include opportunities to study global warming at such farflung locations as the Arctic and Australia's rain forest."
