I agree, to an extent. If the parties in this country aren’t doing enough nationally, and they aren’t, then we have to try to do something locally. The Democrats don’t deny the science of global warming. They support green energy, recycling, better vehicle standards, etc. They also support an economic model that undermines environmental regulations, and they agree with an economic model that in a thousand different ways harms the environment.
I think of it this way; the gap between what needs to be done versus what the politicians you claim are “pragmatic” are doing is vast, and that gap is the rate at which things are getting worse at an exponential rate. You can argue for that for a bit, but at some point (and we’re there), not calling for the radical changes is an abdication of responsibility. Your candidate the last election did support fracking worldwide. She did support an economic model that is a key driver in environmental degradation. She didn’t support things like carbon taxes that could help a bit, they have in the Netherlands and other countries, but that was a step too far for her top donors.
Before you talk about what is or isn’t realistic, realize that any party worth a damn would be talking about the implications about not doing what is needed. They wouldn’t only be going much further in their proposals, which your party needs to do but won’t, they’d make the failure to do so a centerpiece of their campaign. Cause, you know, it’s hard to be “pragmatic” when the environment makes a functioning human civilization impossible, and it isn’t as if global warming is the only environmental issue that is at the crisis stage. Take a look at the Stockholm Resilience Center’s “nine planetary boundaries”. We’ve surpassed a majority of them, and there are other things we could address that they don’t, like the waste from nuclear energy, plastics in the environment, etc. I will take what your party is offering over nothing, which is the alternative, but it isn’t enough, and your party has been very important in the spreading of economic policies around the world that makes tackling this a lot more difficult.
