I agree that it's human fault. But what can we do?

Human overfishing was controllable. It was habitat destruction that killed salmons. And sea lions made it impossible to control the habitat destruction.

When salmons were dying out due to the dams, people got alert and made salmon path at the dams. It didn't work out. Sea lions have guarded the path and practically annihilated them.

I read an old articles at National Geography called "Face of the killer". It explained a lot of effort to keep the peace. But the sea lions are just too smart. The salmon program manager have begged for years to kill just a few notorious sea lions while salmons are dying out. But animal activists have stood strong for the sea lions. Not even single sea lion who were the most infamous.

There are really only three choices;

1. Kill few sea lions
2. Leave salmons die out, which will devastate all the sea lions as result.
3. Blast the dams.

I think it will be fun to blast all the dams. But then I don't think it will happen.

By the way, most of sea lions survive fine without feeding at the dam. It's matter of only a few smart ones who figured it out.
