Is there hope under water?

Is there hope? And where on earth can you find it? The Weekly
Review sets out on a quest for light among the lingering gloom of
2020. Can we find it underwater, with Netflix documentary My
Octopus Teacher? Is it in Greenwich Village, where Fleet Foxes
lurk? Or is hope to be found in throwing out our smartphones, as
The Social Dilemma seems to want us to do? Johann Wald, Mar
Vallverdú and Ben Cardew are your adventurers in optimism.
