Original sentence: Geotherapy regenerates natural life support mechanisms, while Geoengineering aims to replace them with technological solutions.To avoid confusion between antithetic concepts, Geotherapy, sometimes also called BioGeoTherapy to specifically highlight its focus on the regeneration of natural biological mechanisms, is in direct contrast to hard engineering solutions
Edited sentence: Geotherapy regenerates natural life support mechanisms, while Geoengineering aims to replace them with technological solutions, many of which are expensive, unproven, and in some cases may have unexpected side effects worse than the problems they aim to solve.Nor should Geotherapy be confused with New Age practices which no foundations in science - for example using semi-precious stones to "heal" the body.Nor should it be confused with the use of mud mask applications for cosmetics.To avoid confusion between antithetic concepts, Geotherapy, sometime also called BioGeoTherapy to specifically highlight its focus on the regeneration of natural biological mechanisms, is in direct contrast to hard engineering solutions
