The Living Earth Ethical Principles: A Family for All Families

摘要

A Family for All Families. Until the human population returns to a number that the Earth can healthily maintain, all couples should moderate their reproductive fruitfulness. Those wanting larger families should consider adopting as many children as they have the longing and means to raise. All families should focus on teaching their children to tread as lightly on the Earth as possible. We need to shrink the human population as fast as humanely possible if we expect the majority of humans to live inanything but the most abject state of poverty on a disrupted planet with ecosystem services increasingly less able to sustain humanity. But a reduction of how much, exactly? The conservatively calculated Ecological Footprint indicator suggests that the Earth can sustain about 2.1 billion high-income individuals or 6.2 billion middle-income individuals or 13.6 billion low-income individuals (this assumes all of Earth's biocapacity is used for humans). Few will be willing to return to a state of poverty,nor should they, so really we need to aim for either a high-income ("consumer") population one-third of today's population (and no one else), or, more realistically, a larger but still much-reduced middle-income population—one that maintains a simple but satisfying way of life.
