Looking at the the last few hundred years; is it safe to assume that humans will be 8-10 feet tall by the year 3000? Or does the human body have a height limit?

A lot of evidence suggests our height is increasing due to better nutrition in childhood. Height did not increase continuously through our existence, it really kicked off around the middle of the 1800s, before then it was semi-stable.

For that matter, height has actually declined on occasion in regions and populations where access to nutrition has been severely hampered. 

In essence, it seems like we likely have some general 'human height' and that we more often approach the 'maximum' now because a larger percentage of us get adequate nutrition to support growth.
