Some of the issues that came up during a quick Google search for environmental issues: Climate Change Conservation Energy Environmental degradation Environmental Health Genetic Engineering Intensive Farming Land Degradation Soil Land Use Nanotechnology Nuclear Issues Overpopulation Ozone Depletion Pollution Reservoirs Resource Depletion Consumerism Toxins Waste

  3. Food Distribution Maps Percentage of population that is undernourished Daily grams of protein per person Daily calories per person Daily grams of fat per person

  4. Life Expectancy & Population Growth

  5. Dare I say it? Consumerism Your thoughts?

  6. Are you an eco-consumer? Do you consider the consequences of consumerism? Have I just ruined your day?

  7. How about Styrofoam containers from restaurants? Weeden to-go container Number of Styrofoam containers I have avoided by bringing my own

  13. Groundwater depletion (mm/year) Groundwater recharge (mm/year)

  14. Glen Canyon Dam: a lesson in hydrogeology

  15. What does all this mean for your future water security?
