Estimation

There haven't been many posts recently. I've been very busy. Further to the last post - the estimation went like this:
We thought that there might be 100 trees per row and 100 rows, meaning that 10,000 trees had been cut down. It seems a lot.
Next estimate the height of the turbine in the picture and the length of one blade. This turbine is at Watchtree.
