If we look at the way the world is going now and try to imagine a long term vision of its direction, say, in 500 years, we may reach the conclusion that everything may be very different but may be all right. The world population may be much smaller, the energy being used may be based on daily solar radiation, life may be very local like it was through most of human history. Education will then surely be a tool to socialize children into the human world, a critical skill in a sustainable society that is trying to grow and thrive.
That may be the 500 year view but today to stop the destruction of nature and culture, to save the seeds for that 500 year future, homeschooling may be the appropriate step in today's world.
