Apex predators are those that are at the top of their local food chain and are not prey animals to any native species.
Humans, by virtue of agriculture and animal husbandry, and by being at the top of every food chain, are not classified as an apex. We're a step above even that.
We are more "manipulators", able to transform entire ecosystems by simply existing in them. To call us a predator would be to demote the absolutely all encompassing affect we have on the planetary food chain.
