Cow Milk : Myth or Must

I found this article from BIO-GREEN handbook quite interesting. Do you?

In nature, animals are born naturally male and female, the females will feed their inafct with its own milk. Each species of animal milk content different nutrients of animal milk content different nutrients that are only suitable for the babies of their own. That is what nature or god intends to provide. Therefore, we cannot say that cow milk is fit for all beings, it should be fit for calf only and not intent for human being. Therefore, we should follow the natural rule of principle, otherwise, we may face degeneration or illness more frequently.
