A great thought, but much of our waste is outright dangerous to animals. Think sharp half-opened cans that bears cut their tongues on, plastic multipack can straps that the necks of smaller animals get stuck in.

If you want to make waste accessible, you'll have to separate it into stuff safe for animals, and the rest, and since many tourists can hardly clean up after themselves, this seems like a herculean task to me. Plus encouraging possibly dangerous animals to get close to human areas might not be the smartest thing to do.
