  3. McKibben’s “End of Nature” • Main Point: Natural nature has been replaced by an hybrid nature in whose processes human beings now play a part. • Humans have changed the land, forest, air, atmosphere, ice/glaciers, oceans, rivers/lakes—all that composes the “environment” • We cannot escape them by fleeing to the woods. We have progressed beyond removing parts of the earth from the domain of true nature -- through farming, mining, construction -- to actually altering the global processes that define our environment. • Our environment is now in part defined by our actions • ME: Think about what we have built in this process of change • Humans and natural nature are now “tightly bound”…Our cars, our houses, plastics, and pesticides are as much a part of the world we know as are the trees, waters, and hills that we live among. The human race will need to decide between our material world and the natural world. "One world or the other will have to change.” • In this world,McKibben thinks that human beings could take a less dominant relation to nature, and nature might once again establish itself as independent, constant.

  4. Unsustainable Stats • Water - by 2025, 1.6 billion people will live in countries with absolute water scarcity; 440 million school days are already missed every year because of diarrheal diseases. • • Land use - modern agriculture exploits land more intensively than it has in the past. In 1987, a hectare of cropland yielded on average 1.8 tons of crops, today the same hectare produces 2.5 tons. This increased productivity comes at a cost - overexploited land is degraded and becomes less productive. • • Fish - 2.6 billion people rely on fish for more than 20% of their animal protein intake, yet as the intensity of fishing increases, the biodiversity of the ocean and the ocean's capacity to produce more fish decreases. • • Air - more than 2 million people die each year because of indoor and outdoor pollution.

  5. Global Ecological Footprint

  6. Unsustainable Consumption • Affluent: individual average footprint of 21.9 hectares per person estimated by UNEP, includes the areas required to produce the resources we use, as well as the areas needed to process our waste. • Pop Growth: Almost 6.9b today, estimated to reach 10b by 2050. We add 1/3 of the US population to earth every yr.

  7. What is Unsustainable • Environment – Air and Water Pollution • Poverty • Inequality • Disease (AIDS, Malaria, Dengue, etc) • Food/Agriculture • Water • Economic Development • Fisheries • Forests • Energy • Climate • Health • Biodiversity • Ecosystems

  8. Freshwater • Nearly ½ World’s population will experience water shortages by 2025
