The cost of the average Christmas lunch is estimated at £14 per person but the ingredients could have flown 84,612 miles producing the same amount of greenhouse gas from planes as 50,000 three-bedroom semis in a year. In 2004, the UK sent 744 million Christmas cards; if they were all recycled, it would have saved 248,000 trees. In 2005, only 82 million cards were recycled but it diverted 1,630 tonnes of rubbish from landfill sites. In 2001 only 1.2 million of the 7.5 million Christmas tress bought were recycled; the rest created enough rubbish to fill the Albert Hall in London three times
