According to Smith, the regions of the country where invasive plant species are most widespread are those under the most pressure to develop, such as suburban communities, summer vacation spots or natural-resource extraction sites.

When Steven Hawking appeared at Beijing's Great Hall of the People last summer, crazed fans rushed the stage. I know young women who get weak-kneed at the mention of Albert Einstein...
