Does sustainability in business mean companies have to die?
That's obvious in your garden and in the forest. Older trees eventually die to give way to the younger trees. Last year's tomato plants are pulled and composted, and this year's crop is planted.
As sequoias may last for centuries and tomatoes last a season, different companies have different lifespans. We shouldn't uproot a healthy sequoia seedling after a season, anymore than we should try to keep that tomato plant producing into the next century.
And there are indeed challenges. When companies fold, people have to find new work, and that doesn't always happen at favorable times. When companies fold, we may lose access to products and services that provide part of the support for our businesses or our lives. We have to think well about how to deal with such transitions.
Yet a key factor in enabling births in an environment with finite capacity is deaths. A key factor in enabling growth in companies and opportunity for people may well be to allow companies to die with dignity.
