Here is a classic by physicist Tom Murphy.
This is my favorite talk on limits to growth, the most important topic almost no one discusses, including people who should know better, like the Green Party.
Note that Murphy does not mention the explosive worldwide growth in debt, which is the only reason the game has continued longer than engineers like myself predicted it should.
The problem with our reliance on debt is that when the correction comes, it will be much more violent and damaging than it needed to be, which is another topic that the Green Party, and almost everyone else, does not discuss.
In summary, the most important things we should be discussing, are the things we never discuss.
Isn’t that an amazing behavior for an otherwise intelligent species?
