An interesting article. It is stated that the giant pandas certainly paid their way in the first two years of their arrival, despite the £600,000 per annum rent, but during their time at the zoo the cost of their bamboo has increased from £70,000 per annum to £100,000. For the third year there has been no baby, sired by natural or artificial means, this of coarse would have a great increase in visitor numbers but as yet, this has not unfortunately been the case, I find the situation Edinburgh now find themselves in to be worrying in that as time progresses further, without a baby public interest will decline even further in the remaining time of this ten year rental agreement, combined with rising costs the article states it could result in financial ruin for this zoo, if this is the case, Edinburgh Zoo have placed themselves in a very precarious financial position, pinning everything on the birth of a giant panda cub, hopefully it will be better luck next year, but meanwhile they still have to pay £12,000 per week in rent to the Chinese for the next six years.
