redesign the "islands" under the cambie bridge
The current granite rubble covering the piers of the cambie bridge is both ugly and sterile. This area could be easily redesigned into a viable habitat that would provide a sheltered/inaccessible piece of false creek to encourage both terrestrial and marine wildlife.

An interesting idea... However, keep in mind that although the rocks may look like a sterile environment to us, marine invertebrates and fishes can make their homes there. They use the rocks for shelter from the weather and from predators.
Certainly improvements could be made, perhaps expanding the surface area or adding a bit of terrestrial vegetation, but I believe that any changes would be more aesthetic that environmental.
Don't take this as outright criticism - I like the idea in principle, I'm just not sure about the location. I'd like to see marine ecosystem improvements in Vancouver, to help maintain marine ecology as well as to improve quality of life for those of us who live in the terrestrial environment.
