Thriving Natural World is an indispensable vital condition that we all depend on for our health and well-being. A thriving natural world provides clean air, clean water, clean land, and well-functioning ecosystems. Lack thereof can lead to acute and chronic health problems ranging from premature death from air pollution, cancer from land and water contamination, developmental disabilities from mercury and lead, and a range of other detrimental outcomes. Where direct health impacts are not a concern, environmental degradation can still threaten the natural systems upon which humans rely. Pesticides can break links in the food chain, polluted runoff can destroy productive estuarine systems, and climate change can cause severe weather events, flooding, and change growing conditions in food producing areas.
