The cards are on the table. Renewable energy alone or tinkering a bit with new banking regulations or off shore investment controls will make no major difference whatsoever, and gibberish talk about increasing productivity (i.e. financial output per employee) or GDP will not solve the problem but merely accelerate the downfall.
The theme is ages old. And if the roots are not taken out, the weeds will continue to spread. Unfortunately there is no gardener to do that, there is no grown up to take our dangerous toys away. But there was advice from wise men and women throughout history who seem to have been somewhat more grown up than the rest of us. Either mankind listens, or perishes. Both is fine for nature.
