"We face unprecedented pressures on resources and on our environment, as human population and standard of living both surge on a finite planet. Nature will not allow this trend to continue indefinitely."
"Many people, including environmentalists, often avoid linking the multitude of environmental problems to overpopulation. Some believe that a global shift to veganism could support the current population and more. Others attribute the crisis to various factors [that] are frequently cited as primary contributors to the ongoing environmental crisis, overshadowing the impact of population growth."
"Humans collectively must ultimately face the uncomfortable question of whether Earth’s natural systems can support 8 billion or more people at a modern standard of living. Since the resource footprint of a U.S. citizen is at least four times that of the global average, the key question is whether the planet can support an increase in material throughput four times higher than present when the strain is apparent already. As noble as it may be to wish [for] a modern living standard for an eventual ten billion or more people, it is likely that committing to such a course could result in more human suffering than would transpire under the adoption of more modest goals. The responsible path is to reduce global resource dependencies and abandon the imperative for growth starting now."
"This moment is special because we have dramatically built up our population, technology, science, medicine, and democratic institutions as a direct result of vast amounts of surplus energy stemming from a one-time resource. The fossil fuel experience has made us dangerously confident about our cleverness and dominance over nature. What makes this century special, then, is that we will have to cope with a diminishing supply rate of the resource that has been of paramount importance to our high-tech existence."
"[Theres an] excessive number of humans who [want to] live a lifestyle that promotes equality, along with [others] being minimalist and/or vegan... [and] similar overpopulation by other organisms is considered a plague."
"Our fossil fuel bonanza has left our ecosystem in a perilous state. We have destroyed vast forests and habitats, polluted water and soil, kicked off a rapid climate trend that natural systems may not adapt to quickly enough, and basically overrun the planet."
"What did we do with our fossil fuel bonanza? We exploded population by revolutionizing agriculture [and health]. Now when fossil fuels inevitably (and soon?) decline, we’re left with an overhang that can no longer be supported. The resulting population decline will suddenly cast Malthus in a new light: oh what a starry-eyed soothe-sayer [sic]! When that day comes, […] realize that it’s no more tragic than the ant colony waning as it must."
