Using both plants and animals for food by humans is supported by both the Bible and Biology.  The biological truth is that animals themselves live off the death of other living things, be they plants or other animals.  In this sense, death is essential for life because death provides the building blocks and fuel for life.  In many of its films, Disney promotes a fictitious view of nature.  Case in point is Bruce, the great white shark in Finding Nemo, goes to a recovery group where he is taught "fish are friends, not food". . .
