It is a great section, thank you for sharing and pointing out that last part to make it stick.

It makes me think of how people lose bone mass in micro-G.It's a problem that's easy enough to deal with: have powerful wind machines to stress the trees, or robots that every so often push and shake the trees. Heck, have schoolchildren go out and shake the trees once a week, at least until the trees are so big that you're back to wind machines and/or robots.Robert SmithSpace Studies Instituteweb: http://www.ssi.orgthe space studies institute is a 501(c)(3) non profit organizationfounded in 1977 to promote the education and engineeringfor the Human Breakout Into Space
