If a number of individuals sharing a depletable or degradable common resource (such as a stable climate) each carry out and act on their own individual cost-benefit analysis, then non-one has an incentive to act in ways that preserve the resource. This is commonly known as the ‘tragedy of the commons’. It does not happen because people are ignorant or stupid but because they are uncoordinated. Small groups of people can be good at coordinating themselve, but large groups of people commonly choose leaders to undertake coordination tasks. When they do so formally, by voting, it is called ‘representative democracy’.

One of the advantages of representative as opposed to direct democracy is that elected representatives can specialise in considering complicated issues and appoint others to do the same. If, and only if, you are an anarchist, then you can consistently say that this system is too ‘elitist’ for your own taste, but by no measure can it be called ‘very’ elitist.

As to ethics and the valuing of human life, where does he stand on the question of including agriculture in any emissions reduction program which is the economically first best answer in terms of efficiency with the dilemma that it is likely to reduce production and therefore increase price when there are significant numbers of people suffering from starvation or malnutrition in the current period.
