No they do not get cancer just like humans do. If you read that article better you will see they mentioned Tasmanian devils with that specific type of contagious facial cancer. Cancer is not contagious for humans...so it very well could have been picked up and spread from a virus or such.
Also, all of the other animals mentioned in your link are sea animals whom roam about where there is much pollution possible, thus they can get disease from that.
Animals in the wild do not get sick like us from a spiritual deficiency called rage. You do not see hundreds or thousands of lions or antelopes or brown bears for that matter, dying of cancer. It just does not happen. Sorry, you are just incorrect and you do not know how to debate without getting low and calling me stupid. That is OK though, I am not annoyed at you.
They DO get cancer like humans do. That a particular form of cancer is spread by a virus (created by God) doesn’t obviate the FACT that...
a) they are wild animals
b) they get cancer
Thus the inescapable conclusion: Wild animals do get cancer.
So is it pollution that causes cancer, or a spiritual deficiency? Both? Split the difference?
Why does pollution cause cancer in your world?
In the real world pollution causes cancer because it increases the incidents of SOMATIC MUTATIONS.
Thus indicating, along with billions of other points of data, that Cancer is a GENETIC disease.
Be annoyed with yourself - and whoever taught you what you think you know about the mind of God and its applicability to making factual determinations about the natural world. It is well deserved.
