We are already perilously close to killing off the top of the oceanic food chain - with catastrophic consequences that we can't begin to imagine. Let us not, in the heat of anger, reduce the already devastated population of great white sharks by one more member.

Without sharks, you take away the apex predator of the ocean, and you destroy the entire food chain.

If you take away the predators in the prairies and the national parks, you suddenly have an explosion of elk, and then you have a lack of the food source for the elk, so they strip all the ground bare and that takes away the cover, on and on and on and on. The whole food chain is disrupted.

Food safety involves everybody in the food chain.

Supermarkets don't really sustain a community, and they completely remove people from the food chain.

When you're a dancer who is injured, you are at the bottom of the food chain. We are so replaceable.
