I finished watching all episodes in one set. Very very interesting. If in the beginning of the series I knew exactly what I think about genetic modifications, I wasn't so sure by the end of the last episode. Should we leave natural selection to mother nature or take it into our hands? Should we save and or cure every sick person? When we don't see them, know them, it is one thing, but we start thinking differently after we get to know them, like in these series. Does science exist for the sake of science itself? Seems so if no one can afford to use its discoveries and technologies. This applies not just to very rare genetic conditions, but to illnesses that affect thousands. Institutions of science seem concerned (in the series) almost exclusively with health and perfection of a physical body, leaving mental, psychological health out of equation. It is uncharted territory, but it is emotions that make us human. I was waiting to hear about The Gaia hypothesis, yet, no one has mentioned it. I think it is extremely important for every scientist to know, understand The Gaia principle which proposes that living organisms interact with their inorganic surroundings on Earth to form a synergistic and self-regulating, complex system that helps to maintain and perpetuate the conditions for life on the planet BEFORE they start messing with genetic modification of all things alive. Be it a human, or a rat or a mosquito.
