Last month, I had the privilege of attending a Wege lecture at Aquinas College in Grand Rapids, Mich., where Daniel Janzen, the world-renowned biologist, was the presenter.
Professor Janzen, of the University of Pennsylvania and the Guanacaste Conservation Area in Costa Rica, and his wife, biologist Winnie Hallwachs, have witnessed how the incredibly biologically diverse area of Costa Rica was becoming gobbled up to development. Rather than lament and throw up their hands, Daniel and Winnie acted.
They partnered with the Costa Rican government, other governments and friendly foundations to launch the Guanacaste National Park Project. The restoration of this northwestern part of Costa Rica, known as the Area de Conservación Guanacaste, has been one of the great miracles of modern-day biology. There are now 190,000 hectares of restored land in this region. (The entire country is about 151,000 square kilometers, about the same size as the state of Michigan.)
