Can people manage nature? Managing Resources
Make a List of how we manage nature: • Conservation areas • Zoos and wildlife parks • Control animal population with hunting • Kill pests with chemicals (pesticides) • Kill weeds with herbicides • Where, when and what we can build (environmental impact assessments)
Tragedy of the Commons! • A "commons" is any resource used as though it belongs to all. In other words, when anyone can use a shared resource simply because one wants or needs to use it, then one is using a commons. • For example, all land is part of our commons because it is a component of our life support and social systems.
A commons is destroyed by uncontrolled use- it is not important if it was destroyed on purpose or by accident • An example can be when we use land any way we want.
Ecological Footprints !!! • All our activities have environmental effects that can be understood in terms of land area required to support us, our footprint. • When the footprints of the total population of the world exceeds the land available, the population is not sustainable!
So, can we have a sustainable future? need to think about population control technology our footprints wealth the “commons”
