Recommendation 4 - Mitigating Climate Change
Human activities are causing the increase in global temperature
Must address climate change in aggressive coordinated fashion Cannot wait until scientific knowledge is
complete- earth is too complex Stabilizing climate requires a comprehensive

What Kind of World Do We Want?
Those who live in developed countries are the source of most of the problems facing the global environment Assumption made that environment will take care
of itself This view needs to be changed radically

What Kind of World Do We Want?
Most critical environmental problem is our own attitudes and values
Your generation must be the next pioneers Explore a different way for humans to exist in the
world Requires reconnecting with natural environment Requires revaluing ourselves according to a new
set of ideals What kind of world do you want to live in?
