Leadership And The Environment

What is Earth's carrying capacity? Why is it important?Many ask how we will feed 10 billion people. Mathematician way of asking is if we can feed so many and if so how. Maybe we can't.First, don't want to know. While it depends on many assumptions that aren't hard or measurable numbers, like standard of living, distribution of resources, and technology, we can say it's maximum misery per person.How do we narrow it down? Could ask resources per person and how much resources Earth can provide. Limits to Growth projects how much planet would sustain from a systems perspective including history and how we live our values.I prefer a historical perspective I learned from Alan Weisman based on the Haber-Bosch process, which enabled artificial fertilizer. Before artificial fertilizer, limitations on fixing nitrogen to grow food suggest Earth could sustain about 2 billion, enough to create Einstein and Mozart. Want people like Jesus, Buddha, Laozi, and Aristotle? We needed only a few hundred million to create them.If
