I saw an article about the arrests in Brazil of people involved in illegal logging and it said that the estimated area of forest they had cleared was the equivalent of 52,000 football (soccer) pitches.
The use of a football pitch is very common nowadays as a measure of area. With a small number it is fairly easy to visualise the area described, but I cannot for the life of me begin to visualise 52,000 football pitches.
Furthermore, the size of a football pitch can vary greatly. The width can be anything from 45 metres (50 yards) to 90 metres (100 yards), and the length can be between 90 metres (100 yards) and 120 metres (130 yards). This makes it impossible to guess what the loss to the Brazilian forests is. It's certainly big, but I have no idea how big. wouldn't it be easier to give the figure or to use a more natural comparison?
