Assay

In our world there are a lot of places that make fun for people. One of these places is a zoo. In this place people can see a real animal in a cage, feed them and learn about them.
On the one hand the zoos are sometimes imprison a rare species, that there are only few animals from this species all over the world, and if the zoo can't imprison this species and take care this animals, maybe this species will be destroy from our world. The other animals in the zoo are living in a captivity, but they are get everything they need without do anything, they get food, water, place to rest, anther people from their species and if they seek there is a veterinarian that heal them. Another important reason is that in zoos we can do scientific research on the animals and to learn about them.
On the other hand, the animals in zoos are live in captivity, not in original home territory, where any living creature wants to live. The zoos get them out from their original way to live, they shouldn't hunt, they don't have a big places to leave in them as they have in the nature, and they do all the thing different then they do this thing in the nature.
In summary, I think that we should continue captivity animals in a zoo, I think that there are more advantages then disadvantages, and we should continue do it.

Animal testing

Animal testing is a use of animals in scientific experimentation. Many different organizations are doing experiments on animals, for researches in the fields of medicine, psychology, cosmetics and detergents. This issue is a very complex issue, and there are a lot of opposite opinions about it among the public and among scientists in particular.

On the one hand, Testing on animals has helped develop vaccines for many life threatening diseases. The cure and the vaccine for AIDS were discovered by animal testing; also, most of the development in finding a cure for cancer is based on animal testing. For a fact, the animal testing is required in order to make a progress and advances in the field of medicines.

On the other hand, there is a big ethical problem about this issue. The animals, which are forced into these experiments, are suffering intense pain and usually being held under disgraceful conditions. Almost all the animals are being killed after the experiments, if the experiment itself didn't kill them. In fact, every minute an animal dies as a result of an experiment - just in the United States. Also, the animal's body reacts differently from the human's body, so the results are sometimes misleading and can be very harmful for the human's body.

My opinion is mixed. On the one side, I think the experiments are very cruel for the animals. On the other side, I understand that there are sometimes significant experiments, that are obviously can't be tested on humans. In summary, I think scientists should minimize the animal experiments that made for the cosmetic industry; and do the combination of the serious, important, practical experiments, with appropriate conditions for the animals.
