Most people dislike unnecessary Killing of animals. Every creature on this earth feed on some other plant or animal. Life in the wilderness is cruel and merciless. Many animals die of starvation due to draught, winter, and carnivorous animals kill smaller animals for meal. Many hatchlings and baby animals give their life to predators. Only a minuscule fraction of baby animals survive in wilderness escaping the hands of predators. Again killing and farm animals and fish is a way of life all over the world.
Human race is continuing to develop medicine, food and knowledge to help animals survive and grow. There are a many life saving drugs, vaccines and improved food items are now available for animals developed by biological scientists. Cattle herds and poultry are taken good care because of their economic value. Many organizations and activists strive to save wildlife and protect their habitat from human disturbance. There is a worldwide awareness about the conservation of animals and their habitat. Special programs are being taken for endangered animals. So we can say that its no that we are only interested to cause harm to animals, we also are quite aware of their interest.
In conclusion, we can say that If we want to introduce new food items, drugs, or any such thing, we have to get them tested, preferably on test animals, before you apply them on human beings. We don’t have any other option other than testing the developments in the biological sciences on animals. If there is any life-less alternative available, presumably scientist will prefer to test on inanimate things, given that both alternatives are producing same reliable results. We should bear in mind that not all the test animals suffer from effects; often the outcome is harmless to the animal.
