Quantum field theory can be UV finite if it is taken as effective one

This is a further explanation of a new and simple renormalization approach recently proposed by the author (hep-th/9708104, Ref. [1], that is somewhat sketchy) for any ordinary QFT (whether renormalizable or not) in any spacetime dimension. We discussed the physical motivations of the new approach and its efficiency when compared to the existent renormalization approaches. Some other important issues related are briefly touched.
