Most progressive in the Democratic Party doesn't cut it, you know. If we still can't have a health care system that provides health care as a human right, if we still cannot, you know, ban fracking and fossil fuels and move like our lives depend on it - you know, we say in the next 15 years we need to phase out fossil fuels.

Without the jobs being available to enable them to repay that [student-loan] debt in the course of their financial lifetimes, basically.We maintain that, yes, that's a significant chunk of change - it's $1.3 trillion - but what investment is more worth making than in a generation that does not have a future?

When Cuba lost their fossil fuel pipeline when the Soviet Union collapsed in 1990. Overnight they had no choice, they had to transition to clean energy, they didn't have any fuel to burn, and they also had to transition to a healthy food system, an organic system - their economy is crashing, this was not a planned transition. This was a crisis, but a crisis nonetheless, in which pollution went away. And it's very instructive to see what happened to their health.

I have always been involved in issue-based politics, not party politics - I was never really originally drawn to party politics.
