I'm not sure I quite follow, but I'd like to. Are you speaking of personal experience/insight, of studies, or of something else?

I have a hard time understanding why humans are the 'top' of the food chain. I mean sure, we're eaten by microorganisms when dead, but it takes a lot until then to sustain us. Again, not saying we necessarily deserve less, but why do we deserve more? I don't think there are easy answers.
