Salmon or Blackbird - Nature's call?

Business talk is peppered with definitions that more resemble nature than anything else:

"Survival of the Fittest"
"Dog eat Dog"
"Bear or Bull Market"

Last night I was watching a Nature Program on TV (Nature of Britain - presented by Alan Titchmarch). One of the items shown was that always spectacular site of salmons swimming, jumping, struggling up stream.

4 years afters they are spawn and swim out to the open spacious deep sees or oceans the salmon returns to its birth grounds to reproduce. Swimming up river, jumping strong currents and rapids and many die trying. The ultimate reward of making it back to the little stream their own life began is to mate and die.

As I said, always a grandiose spectacle to watch but it left me with a question. Why? In this situation has Nature forgotten its own adaptability? Am I missing something here?

I mean, the blackbird was mainly a wood/forest bird only 50 years ago before adapting to 'city-life' - where survival-rates are better. Numbers of blackbird are increasing.

Salmon is more and more 'thwarted' - by 'human' intervention of for instance building dams, barriers and flood-defences - in its struggle to swim back to the only place they mate and die. The numbers of Salmon is decreasing.

In business it is said that in order to survive and/or grow you have to adapt, be able to change and embrace the most practical way. See and take opportunities to create a better future, to increase the chance of survival.

Would you rather be like the Salmon, 'sticking' to the only known way, perhaps even being applauded for your spectacular efforts, but dying nonetheless or would you adapt to the changing (business) environment like the Blackbird and keep singing your lovely songs?

Just some thoughts from a wondering ponderer.

p.s. Steve, perhaps the ponderings above will give you a different kind of cigar on change? ;-)
