Greener Than You Think

Ward Moore''s classic novel "Greener Than You Think" posits a world with Bermuda grass running out of control -- choking out every other plant and destroying the food supply of animals and humanity alike. Greener Than You Think is a satire rather than an adventure story. One plant (a Bermuda grass treated with a special growth chemical) slowly spreads across California and beyond, swallowing cities and making vast tracks of land uninhabitable. (Goodreads)
