[FONT=Verdana,sans-serif][FONT=Verdana,sans-serif][FONT=Verdana,sans-serif]source[/FONT][/FONT] [/FONT][FONT=Verdana,sans-serif][FONT=Verdana,sans-serif]The conventional approach of landscaping with turf and ornamentals impacts biodiversity in two ways: 1) it limits the diversity of native species in areas dominated by turf and ornamentals, and 2) it can impact surrounding natural environments, altering habitats in ways that exclude native plants and animals.[/FONT][FONT=Verdana,sans-serif]Let’s first look within the city limits.[/FONT][FONT=Verdana,sans-serif]How do turfgrass lawns and non-native ornamental plants impact [/FONT][FONT=Verdana,sans-serif]urban[/FONT][FONT=Verdana,sans-serif]biodiversity[/FONT][FONT=Verdana,sans-serif]? Simply put, landscapes dominated by turfgrass and non-native ornamental plants create an artificial environment that offers very little opportunity for most native species to thrive. A monoculture of turfgrass infused with non-native ornamentals excludes native plants and provides little to no habitat for most wildlife.[/FONT][FONT=Verdana,sans-serif]Think about the vast amount of land devoted to turf, both for growing the sod and the amount of sod that occurs on the landscape as urban lawns. One estimate indicates that four million acres of managed turfgrass occurs in Florida, with 75 percent of these as residential lawns (Nagata, 2003). Such acreage limits the amount of natural habitat, thus decreasing urban habitat diversity and ultimately native species diversity.[/FONT]

[/FONT][/FONT][FONT=Verdana,sans-serif][FONT=Verdana,sans-serif][FONT=Verdana,sans-serif]source[/FONT][/FONT][/FONT]Approximately 50-70 percent of our residential water is used for landscaping, most of it to water lawns, which total approximately 20-30 million acres in the United States. And the U.S. Environmental Protection Agency (EPA) estimates that nearly 70 million pounds of active pesticide ingredients are applied to suburban lawns each year, helping to make polluted runoff the single largest source of water pollution nationwide, affecting ground water, lakes and streams, wildlife, and human health. A 1995 EPA compilation of state data collected in 1994 showed that urban runoff contributed to damage in more than 26,000 river and stream miles. And the use of gas-powered lawn mowers contributes five percent of the nation's air pollution. A gas-powered lawnmower emits 11 times the air pollution of a new car.
[FONT=Verdana,sans-serif][FONT=Verdana,sans-serif]source[/FONT][/FONT][FONT=Verdana,sans-serif]According to the EPA, 95% of the pesticides used on residential lawns are[/FONT][FONT=Verdana,sans-serif] possible or probable carcinogens. In 1989 the National Cancer[/FONT][FONT=Verdana,sans-serif] Institute reported children develop leukemia six times more often when[/FONT][FONT=Verdana,sans-serif] pesticides are used around their homes. The American Journal of[/FONT][FONT=Verdana,sans-serif] Epidemiology found that more children with brain tumors and other cancers[/FONT][FONT=Verdana,sans-serif] had been exposed to insecticides than children without. Studies by the[/FONT][FONT=Verdana,sans-serif] National Cancer Society and other medical researchers have discovered a[/FONT][FONT=Verdana,sans-serif] definite link between fatal non-Hodgkins Lymphoma (NHL) and exposure to[/FONT][FONT=Verdana,sans-serif] triazine herbicides (like Atrazine), phenoxyacetic herbicides (2,4-D),[/FONT][FONT=Verdana,sans-serif] organophosphate insecticides (Diazinon), fungicides, and fumigants; all of[/FONT][FONT=Verdana,sans-serif] which have uses as lawn chemicals.[/FONT][FONT=Verdana,sans-serif]
[/FONT][FONT=Verdana,sans-serif]
[/FONT][FONT=Verdana,sans-serif]Most people seriously overestimate the amount of protection given them by[/FONT][FONT=Verdana,sans-serif] governments regarding pesticide safety. Congress found that 90% of the[/FONT][FONT=Verdana,sans-serif] pesticides on the market lack even minimal required safety screening. Of[/FONT][FONT=Verdana,sans-serif] the 34 most used lawn pesticides, 33 have not been fully tested for human[/FONT][FONT=Verdana,sans-serif] health hazards. If any tests are done, they are performed by the[/FONT][FONT=Verdana,sans-serif] chemical manufacturers, not the EPA. "If a chemical company wanted to, they[/FONT][FONT=Verdana,sans-serif] could start with a desired conclusion, and skew the data, and the EPA would[/FONT][FONT=Verdana,sans-serif] never know", notes David Welch, an entomologist with the EPA's Office of[/FONT][FONT=Verdana,sans-serif] Pesticide Programs.[/FONT]
[FONT=Verdana,sans-serif]source[/FONT][FONT=Verdana,sans-serif]During World War II, women became the focus of lawn-care companies in the absence of their husbands and sons. The lawn was promoted as a necessary means by which women could help support their male family members and American patriotism as a whole. The image of the lawn changed from focusing on technology and manhood to emphasizing aesthetic pleasure and the health benefits derived from its maintenance; it was assumed that women would not respond positively to images of efficiency and power. The language of these marketing campaigns still intended to imbue the female population with notions of family, motherhood, and the duties of a wife; it has been argued that this was done so that it would be easier for men returning from war to resume the roles their wives had taken over in their absence. This was especially apparent in the 1950s and 1960s, when lawn-care rhetoric emphasized the lawn as a husband's responsibility and as a pleasurable hobby when he retired[/FONT][FONT=Verdana,sans-serif]

[/FONT][FONT=Verdana,sans-serif]The lawn aesthetic in Europe and Australia seems to exhibit the same cultural tendencies as a representation of order, power over nature, patriotism, and suburban family life while still adhering to other gender constructs present throughout the world's suburbs.[/FONT]
