With the increase of controlled experiments in modern times, more and more animals are being subjected to dangerous and often life-destroying tests and vivisection such that a substantial number of people are now protesting this inhumane treatment of other species. Many of these experiments are performed in the name of medical science for the purpose of alleviating human suffering. Ultimately a balance must be found in each case between the probable value of the experiment for humans and the actual suffering experienced by the animals involved. In recent generations the average human life-span has been greatly increased, owing largely to the discoveries and practices of medical science. Immunization and vaccination have virtually eradicated the danger of many diseases.
Antiseptic methods control most infections.
Repair of fractures, wounds, and burns have become more efficient. Sophisticated surgeries, including organ transplants and artificial organs, are becoming more common. Various drugs are available. Yet, of course, people still become ill and eventually die. People are complaining in some cases that extra medical efforts are becoming a burden, a hindrance, and merely an extension of suffering in terminal situations.
