We need to aim high - in the area of 20-25 percent - to create the urgent demand for new technologies, manufacturing plants and green jobs.

We're going to bake this planet, and be a curse to all species, including our own, if we don't find an alternative to carbon-based fuel. That's the #1 problem.

All the big ideas for getting us onto a lower carbon trajectory involve a lot of people doing a lot of work, and that's been missing from the conversation. This is a great time to go to the next step and ask, well, who's going to do the work? Who's going to invest in the new technologies? What are ways to get communities wealth, improved health, and expanded job opportunities out of this improved transition?

I had this radical idea that the police should obey the law. My view was that any human system without adequate checks and balances will tend towards corruption and abuse. That's why you have meat inspectors. Not because you hate butchers, but because of an understanding of human nature.

We need to aim high - in the area of 20-25 percent - to create the urgent demand for new technologies, manufacturing plants and green jobs.

If we do nothing, the ensuing climate catastrophe will wreck our economy - including wreaking havoc on our food production systems. All credible scientists agree on this point.

The surest path to safe streets and peaceful communities is not more police and prisons, but ecologically sounds economic development. And that same path can lift us to a new, green economy - one with the power to lift people out of poverty while respecting and repairing the environment.
