For example, doubling the carbon dioxide we belch into the atmosphere may far more than double the subsequent problems for society. Realizing this, the world properly worries about greenhouse emissions.
The butterfly effect reaches into the financial world as well. Here, the United States is spewing a potentially damaging substance into our economy — greenback emissions.
