Young Brunette Girl Posing On The Lawn

A 2010 study seemed to show that lawn care inputs were balanced by the carbon sequestration benefits of lawns, and they may not be detrimental in anthropogenic global warming.
However, using ecological techniques including organic lawn management, the impact of lawns can be reduced. Such methods include: the use of local grasses, sedges, and low herbs; higher mowing techniques; low volume irrigation, 'grasscycling' grass clippings in place; an integrated pest management program; exclusive organic fertilizer and compost use; and including a variety of trees, shrubs, perennials, and other plants surrounding the lawn. A positive benefit of a healthy lawn is that it filters contaminants and prevents run-off and erosion of bare dirt.
In addition to the environmental criticisms, some gardeners question the aesthetic value of lawns, especially in climates and cultures different from the lawn's homeland in England.
