The scale of the human enterprise has increased to the point where Homo sapiens has become a global force. Global change is the
result, an altering the Earth's surface and atmosphere to a degree unknown since the great extinction episode at the KT
boundary, and a disruption unprecedented because it is caused by a single species. The major drivers of this change are the
three multiplicative factors of the I=PAT identity: Population size,
Affluence (per capita consumption), and the use
of environmentally inappropriate Technologies and socio-economic-political arrangements to service consumption.
The most serious Impacts are the extinctions of populations and species,
the working parts of humanity's life-support systems.
The ways global change effects biodiversity and the ecosystem services it supplies,
and what can be done about it, are the topics of this lecture.

Short CV: Paul R. Ehrlich received his Ph.D. from the University of Kansas. Co-founder with Peter H. Raven of the field of coevolution, he has pursued long-term studies of the structure, dynamics, and genetics of natural butterfly populations. He has also been a pioneer in alerting the public to the problems of overpopulation, and in raising issues of population, resources, and the environment as matters of public policy. The Ehrlich group's policy research on the population-resource-environment crisis takes a broad overview of the world situation, but also works intensively in such areas of immediate legislative interests as endangered species and the preservation of genetic resources. A special interest of Ehrlich's is cultural evolution, especially with respect to environmental ethics.
Professor Ehrlich is a fellow of the American Association for the Advancement of Science, the American Academy of Arts and Sciences, and the American Philosophical Society, and a member of the National Academy of Sciences. Professor Ehrlich has received several honorary degrees, the John Muir Award of the Sierra Club, the Gold Medal Award of the World Wildlife Fund International, a MacArthur Prize Fellowship, the Crafoord Prize of the Royal Swedish Academy of Sciences (given in lieu of a Nobel Prize in areas where the Nobel is not given), in 1993 the Volvo Environmental Prize, in 1994 the United Nations' Sasakawa Environment Prize, in 1995 the Heinz Award for the Environment, in 1998 the Tyler Prize for Environmental Achievement and the Dr. A. H. Heineken Prize for Environmental Sciences, in 1999 the Blue Planet Prize, in 2001 the Eminent Ecologist Award of the Ecological Society of America and the Distinguished Scientist Award of the American Institute of Biological Sciences. |
