Currently, science has provided us ways to bioengineer certain new tissues and organs to replace those that do not work anymore or do work, but poorly. There are now bioengineered windpipes and skin, among many others. This is a breakthrough in science as this helps prevent infection, loss of a body function, or even death. There are still a few setbacks in the field, though, as with any other. One of which is the difficulty of engineering the larger and more complex organs, as these types of organs have very important and crucial functions in our bodies, which, if not done properly, may cause fatal complications. The skin gun is one of the controversial bioengineered works, as it is currently not fully efficient given its side effects.
