The Precautionary Principle




















Introduction




Our discussions of global warming have touched on the difficulty of


making long-term forecasts. Suppose the Carbon content in our atmosphere


triples (or more) over the next 100 years ... what will happen to the weather?


The answer is almost impossible to determine because it depends on a number of


known (and unknown) positive and negative feedback mechanisms.




In this exercise, we will explore the different arguments about what to do in the


face of this uncertainty, which is unlikely to go away any time soon. We are going to


study the "Precautionary Principle" as it applies to global warming (it also can be


applied to genetically modified foods and numerous other poorly understood areas in


the biological sciences). To introduce you to this topic, please read the introduction


http://en.wikipedia.org/wiki/Precautionary_principle


from Wikipedia on the Precautionary Principle. There are some good "pro" and "con"


arguments on this page as well for you to use later, so keep this link in mind.




The Debate




Your TA will assign you to one side of the debate randomly. We will work to ensure 

about an equal number of participants choose the "pro" and "con"


positions with respect to the Precautionary Principle (PP). Once it is decided


which side you will research, you will have some time to build your case.


We have provided good links below to each side of the debate.




On your worksheet, before your time is up, write a summary of five arguments


in support of your position.












At the end of the exercise, participants on each side will need to write a 3-5 sentence


summary of their opponent's position, followed by a 3-5 sentence statement of which


side they agree with more and why.

Here are some links for the "pro" PP side of the debate:






The Precautionary Principle handbook is a link-rich site with lots of information on various 

aspects of the PP. Many different articles to explore here.

Here are some links for the "con" PP side of the debate:

treaty advocating the reduction of greenhouse gas emissions by some industrialized 

nations, from a "con" perspective:

From a fan of Ayn Rand's Objectivism philosophy, this website is a concise summary 

of a variety of criticisms of the PP. It is up to you to decide which criticisms are fair 

and warranted.

From the American Enterprise Institute, a lengthy article touching on many key topics, 

many of which can be used as an argument against the PP.
