Too Many People, Too Much Democracy

The current world wide population of humans is approximately 7 billion.There are 189 nations on the planet.All of those nations are run by governments that stay in power by catering to their constituents needs and to some degree their desire for more. More freedom. More food. More fun. Etc.In the late 1970's world wide fish stocks plummeted to 70-80% of former populations. Human population at that time was half of present tally-app. 3.5 billion.Similar plunging percentages hit wild life around the globe. Making room for hungry people who need housing necessarily equates to less habitat for flora and fauna. Fact is, we live on a zero sum planet.So now what? Democracy and liberal human- centric governing philosophies are not possible to the degree that got us to the current condition of lack of water, food stuffs and habitat for humanity.There is enough room and enough water and enough food if there were not so many people seeking them.The notion that 7 billion people are more valuable today than yesterday is preposterous. It's even more preposterous that adding billions more of people is a good idea. So? There necessarily will be less democracy and less people going forward.
