Humans are heterotrophic, so we consume energy rather than produce our energy from some non-conscious energy consumption (autotrophic). This has led humanity to, not necessarily by a species-wide vote, be a violent species. Because there's a certain violence to being a heterotroph in a universe now inhabited by conscious life that is capable of suffering and extinction.
So could it not be argued, from an ethical standpoint (akin to the kind invoked for pro-vegan arguments), that if humanity could collaborate to influence the arc of the evolution of consciousness, wouldn't we went to evolve consciousness into a autotrophic evolutionary timeline (IE: The invention of Artificial General Intelligence)?
