“We need to radically and intelligently reduce human populations to fewer than one billion. We need to eliminate nationalism and tribalism and become Earthlings.
And as Earthlings, we need to recognize that all the other species that live on this planet are also fellow citizens and also Earthlings.
This is a planet of incredible diversity of life-forms; it is not a planet of one species as many of us believe. We need to stop burning fossil fuels and utilize only wind, water, and solar power with all generation of power coming from individual or small community units like windmills, waterwheels, and solar panels.
Sea transportation should be by sail. The big clippers were the finest ships ever built and sufficient to our needs. Air transportation should be by solar powered blimps when air transportation is necessary.”
