Remote controlled floating polar bear rescue "islands". With satelite pictures used by volunteers to steer these platforms They could save polar bears from drowning.
A wacky idea from WW2 to build floating aircraft landing strips out of a slurry of sawdust and water, the whole thing frozen, could make frozen "islands" that would last through the arctic summer. Wind powered blowers could expand the island in winter by using very cold air to freeze more water, growing its size over the cold months.
During summer the island would melt down to it's sawdust/water base. The whole arctic could not be saved in this fashion of course. But maybe a number of floating ice islands could.
Enough to preserve the waning polar bear population until global climate disaster can be turned around? Maybe. Add a clever fish trap and the bears can be fed at least at a subsistence level too.
It's a worthy interim effort to redirect polar bears to more productive foraging and the publicity would highlight the global climate disaster and the whole area of floating renewable power generation from wind and wave power.
It's a crazy plan that would certainly capture the enthusiasm of the young and the young at heart who love wildlife. All the arctic and antarctic animals are very popular, great spokes animals against global climaste disaster! SAVE THE ICE!!!
