i've just been writing an essay for one of my biology subjects and in one of the papers i was using for research it was talking about an experiment done using animals. Basically they had one "germ-free" animal which had no "good bacteria" in its body, and one "conventional" animal which did have "good bacteria". Now, i was wondering why they did it on animals and not on humans, and it appears to me that it's because if we had no "good bacteria" in our bodies, we'd be as good as immunosuppressed (open to infection), which clearly isnt good and could well kill us. So why did they do the experiment on animals? well you kinda have to weigh up the pros and cons of it all. pros are that the knowledge of certain biological processes in the body will be increased and/or new cures/vaccines/drugs can be made to treat certain illnesses. Cons - many animals die/become severely disabled leading to being put down and some people reckon that animals dont have rights.
So, in a nut shell, i really dont know what to think about the practice. I think it's cruel, but without it, we wouldnt have a lot of the drugs/cures/vaccines we have today.
so guys what do you think?
