Civil disobedience has an honourable history, and when the urgency and moral clarity cross a certain threshold, then I think that civil disobedience is quite understandable, and it has a role to play.

The wind and the sun are free.

For me, the most serious problem is how America became so vulnerable to the assertion of blatant falsehoods that drive policy and are not corrected by the so-called immune system of democracy, a free press and a free democratic discourse.

We're still putting 110 million tons of man-made global pollution into the air every single day as if the sky is an open sewer. More than 90% of the extra heat energy is going into the oceans, and that's why superstorm Sandy was so much more destructive, that's why the ice is melting more rapidly, that's why the water cycle is being disrupted and we get a lot more water vapor coming from the oceans into the sky, and that's why we get these enormous downpours and big floods. They happen all the time. Every night on the TV news is like a nature hike through the Book of Revelation.

Now comes the threat of climate crisis - a threat that is real, rising, imminent, and universal. Once again, it is the 11th hour. The penalties for ignoring this challenge are immense and growing, and at some near point would be unsustainable and unrecoverable. For now we still have the power to choose our fate, and the remaining question is only this: Have we the will to act vigorously and in time, or will we remain imprisoned by a dangerous illusion?

As I have said for many years throughout this land, we're borrowing money from China to buy oil from the Persian Gulf to burn it in ways that destroy the future of human civilization. Every bit of that has to change.

I think the fact that within the bitcoin universe an algorithm replaces the functions of the government is actually pretty cool. I am a big fan of bitcoin.
