Simple question really (and one of my favorite topics in general). Are humans above all other forms of life?
Hmm... i guess if i were to judge humans, critique mankind by how effectively it uses and utilizes what evolution provides it, then i would have to answer 'No' we are not above all other forms of life in value or importance. Why? Because while animals may kill without purpose, exhaust their resources, and inhibit the survival of other species, we alone claim to 'know better' and possess the ability to correct and/or prevent such ill actions by others.
Being set apart by an intellect that allows us to reason, innovate, and improvise would be impressive if it weren't for what do we inevitably do with this 'blessing', namely reap unimaginable havoc on the rest of life and damage ourselves in the process. We are the most wasteful, neglectful, and destructive of species ever to understand what 'evil' is. At best i'd say we're equal, cognizance making up for a lack of physical prowess. At worst, i'm tempted to say we're a plague on the earth.</shrug..]
