Greenleaf Communities was established as a nonprofit 501(c)(3) organization to advance a healthy and sustainable world by recruiting and organizing multi-disciplinary teams of scientists and practitioners to investigate environmental influences on health and inform industrial practices and the policies that support them. We design and support sound scientific research led by some of the country’s leading experts on the environment and human health in order to provide tools and solutions concerning the health and well-being of society. Environmental impacts on water and food security, coupled with events related to climate change, are likely to influence population movements and exacerbate disease, adversely affecting human health. Our programs focus on addressing the environmental sources of human health concerns. Therefore, the research we support investigates the most basic and important natural resources we have: the air we breathe, the water we drink, and the soils which provide the food we eat.
