Wood has many different uses, including shelter, fuel and paper to write on, as well as having a key role in maintaining a healthy planet. More recently however, the development of engineered wood for use in the construction of tall buildings has led to a new generation of ‘ply-scrapers’. So is our attitude to wood changing? This was the subject of a discussion on The Forum of the BBC’s World Service yesterday morning (19 Jan 2015). The panel consisted of architect Michael Green, timber researcher and civil engineer Dan Ridley-Ellis, geographer Reginald Cline-Cole and cellist Steven Isserlis.
World Water Day (WWD) is held annually on 22 March as a means of focussing attention on the importance of freshwater and advocating for the sustainable management of freshwater resources. This year’s theme for WWD on Saturday is “water and energy”, to collectively bring attention to the water-energy relationship, highlighting the 768 million people that currently lack access to water and the 1.3 billion without access to electricity. According to the UN, in order to meet the demands of a growing population, 40% more water and 50% more energy will be needed by 2030. WWD 2014 aims to facilitate the development of policies that link the public and private sector in order to move towards future energy security and sustainable water use.

own Peter Baker has dealt with the subject eloquently this week in an article he
wrote for BBC News’s online forum, GreenRoom.
