What some people are doing is obstructing us from going anywhere. We need to stop acting helpless, stand up for what we believe, fight (peacefully), stop the post-truth nonsense that supports these people, and vote them out of office.
> All human activities, in different degrees, contribute to climate change.
It's kinda true, because of the Second Law of Thermodynamics (and ignoring activities that actively reduce climate change, like installing insulation or voting certain people out of office), but meaningless. Riding a bike and riding a private jet both contribute to climate change, but that's a pointless statement.
> Say that you bike to the office everyday. You enjoy your commute, you never develop a heart condition, and in the course of your long prosperous life you have three kids and nine grandchildren, own several dogs and get a bigger house. In other words, your climate footprint all of the sudden is greater than if you had used a polluting car and died of a heart attack when you turned forty.
That's restating the Second Law, in a sense. But we can do all those things, and still prevent climate change by using different technologies.
> We have the knowledge, the technology and the means to live in domes in the vast deserts of this planet, to go to the moon or to live in space habitats anywhere in the solar system.
What do you conclude from that?
