"Opponents of cap and trade should be careful what they wish for"

This quote by Joshua A. Tucker is a warning to those who oppose cap and trade. It suggests that they ought to be cautious about what they are wishing for, as the repercussions of their actions may not be what they anticipate. Cap and trade is a system of ecological regulation that sets a limit on the amount of contamination that can be released by a company or industry. Opponents of this system may be longing for the elimination of the cap and trade system, but this could cause a boost in contamination and ecological damage. For that reason, challengers of cap and trade need to be aware of the prospective effects of their actions and take care what they long for.
