Dependence Of Animals On Humans
The intelligent design of God is no a perfect one to let it cause different results, which were not possible if the design was a perfect one. Each being depend upon other to feed or to cure itself. This dependence sometimes causes grave and painful situations. Your question is related to the problem of pain. Why God created pain in this world, He could have chosen some other scheme of existence. This question arises from the perception of a Merciful God. The fact is, God is not as merciful as we traditionally assume. Mercy is the ultimate result of the great scheme He has initiated, but the scheme itself is the manifestation of Will, Power, Knowledge and Wisdom and He has told us little about it. He willed it this way to see if we do good deeds or not, believing that the ultimate results will be a benefit in abundance for his creatures.
