The majority of our collective coexistence problems come from the limited perspective we have on the world. it's true that the issues that were listed here are pressing: fossil fuel consumption, deforestation, ocean and air pollution, garbage disposal, overpopulation in some areas etc.
All these come from a narrow and biased view of the world we have. If you talk to any astronaut they will tell you the same thing when you go in space and see our world from above, your experience and understanding of it is transformed. You see it as one thing, one borderless globe. However here on the surface we, mostly, forget about this.
What we need is a better tool to evaluate potential solutions, the one based on the unity of perspectives and the objective data.
