"The essential qualities of a true Pan-Americanism", remarked Franklin Roosevelt in 1933, "must be the same as those which constitute a good neighbour, namely mutual understanding and... a sympathetic appreciation of the other’s point of view." That is advice which the United States would do well to heed in its relations with its immediate neighbours, Canada and Mexico. Most Americans may not be aware of it, but frustrations and resentments are building just across their borders to both south and north.
Of course, neighbourly ties in North America are closer than in Roosevelt’s day. Under the North American Free-Trade Agreement (NAFTA), trade among the three countries has more than doubled since 1994 and cross-border investment climbed even faster. In the aftermath of the terrorist attacks of September 11th 2001, the United States moved quickly to sign "smart border" agreements with both Canada and Mexico, to try to ensure that th

[简答题]Joe Harberg became an energy-efficiency guru because he didn’t know the first thing about energy efficiency. In 2003 he was constructing a new home in Dallas and wanted to work with his builder to make the place as environmentally friendly as possible. But neither Harberg nor his designer had any training in how to turn an ordinary house green, and they found few resources to help them. "It was so frustrating," says Harberg, 46, a Dallas-based entrepreneur.
Relying principally on the Internet, Harberg—who previously had worked as a marketing expert and real estate developer—did manage to build an energy-efficient home. He boasts that his electricity bills are regularly 50% less than those of similar homes in his neighborhood, and the entrepreneur in him saw an opportunity. Lots of people worry about global warming, not to mention the soaring costs of powering a home, but they don’t know what to do about it. Working with his brother-in-law Josh Stern, Harberg helped launch what wou
