Improved Air Quality: A 15m x 15m well-maintained grass area will create enough oxygen to meet the needs of a family of 4 every day. Acting like a gigantic sponge, lawns absorb all types of airborne pollutions such as soot, dust and carbon dioxide.
Electricity Saving in Summer: The front lawns of a block of eight houses have the cooling effect of about 70 tons of air-conditioning enough to cool 16 average homes. On a hot summer’s day grass can be 10-14 degrees cooler than exposed soil and as much as 30 degrees cooler than concrete or asphalt.
Water Quality: Studies show healthy lawns absorb rainfall 4-6 times more effectively than pastures, being exceeded only by virgin forest. Lawn returns the moisture to the water table, where it can again be used by everyone.
Reduction Glare: Lawns help to soften and reduce reflected light, lessening glare.
Health: Lawn maintenance requirements provide an excellent opportunity to enjoy reasonable exercise while enjoying fresh air.
Noise Reduction: Good turf can absorb sound better than heavy carpeting.
