Is animals a non-renewable

Depending on what types of animals one is wanting to know about: For example:

Domestic animals may seem to be a renewable resource as they easily reproduce. Farm animals have been genetically altered over time to reproduce with highly desirable traits, at a greater rate than their counterparts in the wild.

Therefore, one may say theoretically that domestic animals are a renewable resource.

Wild animals are not seen as a renewable resource as environmental scientists will attest to the fact that many animal species have become extinct. It is more difficult to improve reproduction in wild animals, whether in captivity or free ranging. Wild animals only increase their populations when food is plentiful, the range needed to sustain life increases (it has decreased due to human intrusion), when the population has decreased due to some event such as a disease or natural disaster, and when there is not a close relationship between the animals. Even though zoos force the reproduction of animals who are related to prevent extinction of the species. Therefore, wild animals can be said to theoretically NOT be a renewable resource in the same sense that domestic animals are.

However, one may argue that if a disease decimated a domestic animal population where the breeding stock was reduced to a few related pairs, this animal, say a cow, would then become a non-renewable resource. Each generation of these related cattle's offspring would exhibit less desirable traits along with inherited deformities. This would continue until the cow would become extinct, simply because the deformities would become so great the cow could no longer reproduce viable or living offspring.
