I believe Bitcoin will serve this purpose and many others too.

I wrote an article related to how Bitcoin and unstoppable tech can help “protest” movements that are not fully effective (I mention Occupy Wall St in the article, but it applies equally to the environmental movement). That article is not part of this series but is also very short. There’s also an article in this series about how Bitcoin helps, not hurts the environment in long term. Here are links to both:

The new, sustainable individualism.

Why Bitcoin's Energy Use is Not Environmentally Harmful

I’m also very early into writing a novel that has this issue as part of its theme and plot.
