In this blog you can find some interventions made by the man with the living. In my personal opinion, are good interventions because they are things that people do every day and unconsciously.
Interventions are commonly made, as we in the everyday cook animal meat, as well as serious human flesh and that used in the intervention fetus was dead so I did not suffer. We also act unconsciously, as millions of stray dog starvation or cold and we spent the side of them without help, is what he did in his speech Guillermos Vargas, left the dog with no food, no water and no one did anything.
The blog says as some interventions were performed with living things and what were the causes of these.
