 A new poll shows that Americans who were unconcerned about climate change as it wreaked havoc around the world are beginning to worry, now that global warming is affecting the appearance of their lawns. According to the poll, conducted by the University of Minnesotas Opinion Research Institute, rising sea levels, the destruction of habitats, and catastrophic weather conditions, such as hurricanes and tsunamis, have not served as the wake-up call to Americans that their lawns unsightly barrenness has. In interviews across the state of California, residents expressed anger and outrage that climate change had been allowed to worsen to the point that it has now severely limited their choice of ground cover, shrubs, and other decorative plantings. We are being forced to create a front lawn out of stones and, yes, cacti, said Harland Dorrinson, a resident of suburban Sacramento. Im not sure that this is a world I would want to leave to my children. Right now were looking at a situation where we have to choose between saving our climbing hydrangeas or our roses, said Tracy Klugian, of San Diego. We are no longer living like humans. Carol Foyler, a San Mateo resident who has watched her lawn turn from a gorgeous green to a hideous brown during Californias drought, said she blamed scientists for failing to warn us of the true cost of climate change. They always said that polar bears would starve to death, she said. But they never told us our lawns would look like crap.
