1. Environmental Science Introduction Doing Science

2. Environmental Science Interdisciplinary study of humanity’s relationship with other organisms and the nonliving physical environment. Encompasses many complex and interconnected problems Human numbers Natural Resources Pollution

3. Environmental Sustainability Ability of the environment to function indefinitely without going into a decline from the stresses imposed by human society on natural systems that maintain life

4. Non-Sustainable Human Behaviors Using nonrenewable resources as if they were present in unlimited supplies Using renewable resources faster than they can be replenished naturally Pollution the environment with toxins as if the capacity to absorb them were limitless Increasing in numbers despite the Earth’s finite ability to support us.
