I understand your point of view, and that is why day by day professionals who have the possibility to leave these practices aside, have to do it, because it generates a great change.

One of the main reasons that led me to study biomedical engineering is the great change that can be generated in support of animals, from prostheses for them, to design equipment to analyze samples without using animals. but there is a great reality that you and I can not leave aside, that even the technology is yet to evolve and end the use of animals, for it to evolve we must force governments and private companies to invest in technology, in this way we will achieve that this ends.
