Abstract
Genetic engineering (GI) is defined in this book as a set of technologies that may be used not only to change the genetic make up of selected organism by transfer of genetic material. Benefits of GI are discussed and compared with possible risks of gene manipulation.
Further it is shown that risk in view is often irrational or when proper security steps adhere to the terms the risk is negligible. Safeness of gene manipulation and GMO exploitation evolves in parallel with continual improvement of methods of GI and has usually multi-barrier-character.
Main types of safety procedures developed during the history of GI are discussed. Some security procedures are demonstrated that may serve in future for preventing the escape of modified genes or modified organisms to uncontrolled public space.
It is discussed how GI may help as to solve the problems connected with lack of energy and food sources, and increasing pollution of our planet in near future.
