Our transcription: But while Jenkins is committed to building the most effective seawalls he can, he recognizes that they are only a short-term solution.
And he is sensitive to the arguments of those who oppose attempts to redirect or in any way modify natural processes along the coast.
There's a wide variety of environmental groups, and there's a wide range of government officials and university professors who oppose construction and structural intervention on the shoreline.
The reason is philosophical, that we want to preserve the shoreline in its natural state.
Now, those who are going to lose property if erosion continues also have a concern, and those are the people who, of course, are going to favor these structures.
My personal belief is we should adopt the policy of maintaining the coastline in its natural state.
A large part of that policy would involve bypassing of sediments around dams and preventing further encroachment of coastal structures in the near-shore area.
Then I would say having made those fixes, let the system adjust to its own equilibrium.
There's far too much energy out there for man to compete against.
