Document Summary
Sustainability: maintaining the ability to accommodate three important sources of change. Meeting the needs of the present in an equitable and fair fashion without compromising the ability of future generations to meet their own needs. Planet: measured by pollution output, waste, production, energy use, species, conservation etc People: human health and well-being equity, access to social resources, and benefit to community. Ecosystems: all living organisms and their physical and chemical environments. Matter and energy are neither created no destroyed! Law of energy and mass conservation: everything goes somewhere. Water vapor is the most abundant greenhouse gas. Water molecules in the ocean have the longest residence time. We consume a lot more oil than we produce. Leachate is collected from landfills because it may contaminate ground water. Leachate is the liquid bi-product that leaks from the trash. Open recycling system: taking the product and making a different product out of it.
