is the earth a bioreactor[edit]

"A bioreactor may refer to any device or system that supports a biologically active environment." could that include the Earth? should that be added to the article?

No and no. The definition was insufficiently precise. It is now more precise (but may not necessarily be more accurate).  Velella  Velella Talk   20:07, 29 January 2011 (UTC)

NASA Bioreactor?[edit]

Why is there a whole section on the NASA bioreactor? That would make an interesting "case study" in a larger article, but there it's just out of place and bizarre.I'm tempted to delete it.RSido (talk) 02:59, 17 April 2014 (UTC)
