Read this passage from "The City Without Us" by Alan Weisman: The weeds are followed by the city's most prolific exotic
species, the Chinese ailanthus tree. Even with 8 million

their spreading leaf canopies start poking from sidewalk
grates. With no one to yank their seedlings, within five
years powerful ailanthus roots are heaving up sidewalks
and wreaking havoc in sewers.
