Donella MeadowsDr Donella Meadows was a pioneering environmental scientist, academic and systems thinker.

Those that study systems thinking, mention her name in hushed tones. The reason being that she, along with a few others in the field, had an extraordinary ability to simplify highly complex issues into manageable constructs that just make sense.

This keynote presentation from 1993 was delivered by Meadows at a Sustainability Conference in Costa Rica. Sadly she died in 2001 at the very young age of 59, but her inspiring message is as relevant today for everyone as it was 23 years ago.

In our minds, this is the TED talk she sadly was never able to give.

Do yourself – and the world – a huge favour and absorb this half an hour of inspirational wisdom and leadership.
