COHAB 2005 aims to stimulate positive thought, activity and collaboration across multiple disciplines by linking two areas which even most ecologists do not see as being connected (human health and biodiversity) and by advertising the importance of biodiversity and ecosystem health to the Millennium Development Goals. The target audience includes researchers, students and professionals in areas of the biological, environmental, chemical, social and political sciences: biology, ecology, conservation, biochemistry, medicine, pharmacognosy, microbiology, environmental chemistry, sociology, demography, public health, social policy, local government, economics, environmental resource management, risk assessment and others.
