Global warming? When is it going to start?
Everyday in Britain 100 football fields worth of land is lost to development. Some of this land is reclaimed wet land. 100% of rainwater falling on a roof/road/car park runs off into stormdrains/rivers. About 80% of summer rain is absorbed by a sod roof.
Rainwater recycling is a must. Sustainable Urban Drainage is a huge step forward. At it's most basic, it's a permeable surface, with huge storage area just under the surface. The grey water collected can then be reused. http://en.wikipedia.org/wiki/Sustainable_urban_drainage_systems. Apparently for a big retailer to install a SUDS system, it wouldn't work out any more expensive than installing standard drainage.
More sod roofs, especially in urban buildings would help also. There are a number of other benefits to rooftop gardens.
