Experimentation on animals

The experimentation on animals is a very known fact nowadays. It has both advantages and disadvantages.
On the one hand millions of lives are saved because of the experimentation on animals. It allows scientists to test new medicine, drugs, different chemical substances or even food. When they test medicine, they realise what things are good for our health and what not. And thanks to this fact a lot of lives are saved. They test drugs, so they can prevent people from using them showing how dangerous they can be for the health of the human. Another important thing is the food. They test food which is unhealthy and sometimes can kill people. Especially the food with fat, with a lot of calories and E-s. And this fact also prevents people from diseases and even from death.
On the other hand, the experimentation on animals has also a lot of disadvantages. These experimentations make a great pain to animals and almost every animal which is experimentes dies. That's because the substances they experiment on them are not always good. And the drugs- almost every drug is dangerous, so it kills animals for sure. Another disadvantage is that not all the people are impressed of the consequences of unhealthy food, drugs or another unhealthy substance. Usually they ignore the information that is given about the danger of this things. I totally disagree with the experimentation of medicine on animals. Although the oraganisms of the animals are the same as ours, not all the medicine has the same impact on people. The animals receive the medicine in one way, but the human in another way, so sometimes it's a great risk to experiment something like this, both for animals and humans.
So, I think that there are more advantages and disadvantages about the experimentation on animals. But, in my opinion, not everything should be experimented on animals. There are rhings or substances which can be axperimented in laboratories or specific apparatus.
