"We need to radically and intelligently reduce human populations to fewer than one billion.... 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.... Air transportation should be by solar powered blimps when air transportation is necessary. All consumption should be local. No food products need to be transported over hundreds of miles to market. All commercial fishing should be abolished. If local communities need to fish the fish should be caught individually by hand. Preferably vegan and vegetarian diets can be adopted.... We need to remove and destroy all fences and barriers that bar wildlife from moving freely across the land.... We need to stop flying, stop driving cars, and jetting around on marine recreational vehicles.... Who should have children? Those who are responsible and completely dedicated to the responsibility which is actually a very small percentage of humans...."
