An Opinion Essay

To what extent is the use of animals in scientific research acceptable?

Are scientists killers of animals? Lots of animals die every year in scientific research. Most of them are ill-treated and used unjustly.

As far as I'm concerned I think that this kind of scientific reserch isn't acceptable, because we can't ill-treat animals! In my opinion it isn't necessary use all this number of animals to research.

And I can't stand why these animals are used for cosmetics. Much scientifics kill animals to do makeup.

Personally I think that there are much injustices concerning animals, but the scientific research can improve a lot, so our society has to progress.

In conclusion, I belive that nowadays, experiment with animals is unjust but necessary. But I hope in the future will improve, reducing the deaths of these animals.
