It doesn't necessarily have to involve self sacrifice. For example, we could build a world where life is comfortable for most people without a car. I don't know how we actually get there from here. But I'm confident that it isn't effective to make everyone believe that our choices are between 1. short-term personal gratification at the cost of everyone being certainly doomed and 2. short-term personal sacrifice with a very slim hope of marginal collective gain. In that scenario, most people will look out for themselves. Only crazy people sacrifice themselves for no real gain for anyone else. We have to create a plan for short-term personal gain that leads to collective gain long term. Most conversations don't allow for that possibility to exist at all.
