I do not comprehend how anyone can read the Bible to mean that Man's sin would affect the animals and what they eat.

Sin entered the world by way of Adams fall, and death by that sin. Prior to that, it was a perfect world that didn't have death.

You're conflating different things. The world ≠ Eden ≠ the Garden in Eden.

Genesis 2:8 (King James Version)

8And the LORD God planted a garden eastward in Eden; and there he put the man whom he had formed.
