Aside from the effects that animal testing on humankind, there are many cons but little pros that are related to the environment.
Such as the fact that it causes tremendous amounts of suffering, torture and stress for the animals that are tested on.
The companies that are testing on animals might not be aware that what they are doing is harming the environment because they are so blinded by the fact that they are making money.
Pharmaceuticals have rubbish and packaging and people litter, all that rubbish will eventually end up in the ocean.
Animals might mistake it for jellyfish, eat it and die. This would affect the ocean population greatly.
Animal testing inflicts both physical and psychological (mental) distress on animals, which is why in some countries they are trying to ban testing on chimpanzees, monkeys, orangutans and apes, due to their ability to feel emotions, pain and stress more clearly as they are more similar to humans and their genes.
Did you know that animals are sometimes force-fed, force to inhale gases, injections, exposure to deadly drugs, ear and tail clipping, water and food deprivation, purposely inflicted burns and wounds to see the effect?
This is how cruelly they are treated, even if it is in the name of science.
Many people do not realise that animals used in experiments are usually bred in the research area. This means if they were released they could not survive in the wild.
These animals cannot simply be sent into the wild or into homes as they would not be able to cope and survive.
Some people question why this does not happen, but the reality is that it would not be humane to do so despite it seeming like a better option.
But, on the positive side, many animals are euthanised (killed painlessly) after testing to alleviate (lessen) the pain and stress that the animals had to go through.
Animals that are tested on may become immune to some diseases, improving their health and well-being because a majority of lab animals get tested on by vaccines.
Also, most medicines are man-made and that means that many drugs that are sold at pharmacies don’t contain natural resources, meaning that companies don’t have to destroy the environment in order to maintain the ingredients for certain medicines.
Having lab-bred animals allows scientists that are a part of the process of pharmaceutical animal testing to see the potential effects of drugs in the offspring of the animals.
