Figure 4.1 shows how the global area of GM crop production changed in the 17 years since GM crops were first grown.

Figure 4.1, a bar chart of the global area of GM crop production, in million hectares, against year from 1996 to 2012: the bars rise from about 2 million hectares in 1996, through about 42 million hectares in 2000, to about 170 million hectares in 2012.

Calculate the percentage change in global area of GM crop production between 2000 and 2012.
