I remember the first time reading this book, or rather the 30 year update -- https://www.amazon.com/Limits-Growth-Donella-H-Meadows/dp/19... -- thinking, "this is the approach to take to understand how the economy, ecology, pollution, and so on interact."

Everything else was just looking at elements. Technology is important, for example, but exists within a system. They looked at the system. They had to simplify and assume a lot, which the media didn't understand (probably benign ignorance) and critics blew out of proportion (probably maliciously), but I found their approach the most meaningful.

Sadly, I know many people who care about the environment but don't understand the (relatively simple) math in their approach, and many people who understand the math but don't care about the environment, but almost no one who cares and understands. So in about a decade since reading it, I haven't found anyone I can talk to about it meaningfully.

A great companion by one of the authors is Thinking in Systems by Donella Meadows -- https://www.amazon.com/Thinking-Systems-Donella-H-Meadows/dp....

Both changed my views more than almost any other books.

With all respect to the authors, the thinking at that point in time and the impact it made on the world and you: Much of their predictions haven't stood the test of time.

-No exhaustible has been depleted yet and the price mechanism combined with technological progress seems pretty able to set incentives straight. Look at what the oil price bubble of the '00s did for electric cars and batteries in the now. -The world has seen massively more population growth than they modelled, but not the accompanying food shortages they predicted. I'd argue the shortages of the '80s and '90s are over, although local situations obviously have tragic effects (Syria, Venezuela). -Material goods production (plastics) is at an all time high. -Many more humans alive at lower poverty levels than ever before and ever imagined by the Club of Rome

They got the depletion of fish stocks right though. Although arguably, that was the simplest prediction since the 'tragedy of the commons' is so profound in international fishery.

The gloom of the club of Rome just didn't work out. I guess outside of way we are treating our environment, humanity has a lot to be proud of. (I feel the environment is going bonkers and we are a plastic-addicted throw away society.)

> No exhaustible has been depleted yet

What did they predict would be depleted by December 2017, and where did they predict it? Be specific please.

> The world has seen massively more population growth than they modelled

Has it? What does their model predict for December 2017? Be specific.

(http://sustainable.unimelb.edu.au/sites/default/files/docs/M... shows an almost perfect fit of population growth predictions and historical data until 2014)

> Material goods production (plastics) is at an all time high.

Yes, that's lovely. Where did they predict otherwise, for December 2017?

> I guess outside of way we are treating our environment, humanity has a lot to be proud of. (I feel the environment is going bonkers and we are a plastic-addicted throw away society.)

Agreed.

With this kind of long term predictions, it's practically impossible to get the numbers right - ie the number of years it will take for resource X to end, how many billion people Earth can sustain, etc. But this doesn't mean that there are no limits to growth (on Earth): in the last 40 years we invented lots of great technologies that improved the efficiency in how we use lots of resources and reduced the pollution created by production, but there is no silver bullet in sight that could make those disappear.

Just like Moore's law, it worked much longer than anybody expected, but in the end we still hit many limits, and we can say for sure it's not going to last forever even if we don't know when it's going to really end.

Thanks! And are the arguments put forward in these links considered at executive level? Seems to me - not at all because preset agendas dominate, drowning out the logic.

You've mischaracterized their work.

They didn't predict what you said they did. They showed a range of possible outcomes based on assumptions, among many. You seem to have picked one outcome as their only one and called it their prediction.

They created a model based on a systems approach whose output depended on assumptions on physical properties of the planet and future human choices. Given the large uncertainties, they ran the model under many sets of assumptions and presented the outcomes.

The point of the book is to illustrate and promote a systems perspective, not just a linear, event-based approach, which you seem to prefer.
