On the one hand technological advances produce improvements in production on drops, safer and quickness transportation, investigation, development and new vaccines to solve and cure diseases and epidemics, ..... On the other hand technological evolution has drawbacks as dangerous pesticides on drops, risk and big accidents in transportations, high research costs in health, pollution in the environment, .... But the evolution is necesary and is necessary to suffer disadvantages if we want to belong to a developed society. I can or I can't be in agreement which genetic technology, performance-enhancing drugs, pesticides and other areas but I trust the technicians and the responsible staff working accordins some non-malicious rules. Every country has controversial scientific issues as genetic technology, cloning, human enhancement technology, in vitro fertilization, performance-enhancing drugs, euthanasia, ....
