Some people think that spend time and money investigating with animals could be a waste of time and money.They argue that science should try to resolve other problems however I am completely agree with this research because I think it can help us in others concepts related whit the health of the persons and whit the improvement of the medicines.
On the one hand the advances whit the experiments making whit animals keep advances more quickly and best for the improvement of the humanity.
On the other hand people think that animals have feelings , and they have reason , the animals suffer like humans and it is very bad for the health of the animals.
In conclusion, the experiments whit animals are good for the advances in medicines, etc. but it is very bad for the animals and for her health, and it could be prohibited.
