Eight Billion – Our Greatest Mistake

According to the United Nations Population Fund, reaching a global human population of 8 billion is an achievement to be celebrated. In “a world of infinite possibilities,” they state, “imagine the boundless paths 8 billion can take.” Rather than taking refuge in irresponsible fantasies, it’s time our bloated societies reckoned honesty with demographic reality. By … Continue reading Eight Billion – Our Greatest Mistake

The per capita fallacy

Are many tiny ecological footprints more virtuous than fewer, larger ones? Will they be better for the Earth, or easier to accomplish?
