“Reducing the amount of food eaten in the homes of those who travel long distances” should read “Reducing the amount of food that travels long distances”.

Anyone that doubts the long-term seriousness of this problem should read Sir John Houghton’s scientific report Global Warming: the complete briefing (CUP 1997).
