I think the timing proscribes the food chain as a necessary part of
God's good creation.

I would submit that Adam's fall was his failure to set the godly example
that Christ set. The effect on mankind was deleterious due to the
appointed leader being unable to handle the responsibility. I don't think
the creation was impacted beyond a secondary effect. Sinful man pollutes,
drives species into extinction, burns the rain forest, over fishes the
oceans, etc. The "thorns and thistles" may have been outside the garden
all along but not encountered until Adam left the confines.
