Richard Heinberg, one of my favorite and most trusted sources for information about energy and economics, has a short new article out online that I recommend you check out here. As he starts out by saying, “the human economy is currently too big to be sustainable. We know this because the Global Footprint Network, which methodically tracks the relevant data, informs us that humanity is now using 1.5 Earths’ worth of resources.” We need to make major changes that will get things in balance soon, if we want to leave any kind of livable world to our children and grandchildren, and Heinberg has some good ideas on what those changes might be. If we do nothing, the economy will crash in our lifetimes anyway, due to its unsustainability, making life difficult or impossible for most of the planet’s 7+ billion people.
