Sometimes I look around at work and think, "what are we all doing here?"
You're making money that you can then spend on this crisis outside of work
This is a guess, but I think that it makes sense for each individual to specialize for work, doing what you're best at. If you can make a lot of money at work, then turn around and dump a ton of your money into making the planet better, that may end up contributing more to the solution than directly working on it for a living (assuming you're not inventing some revolutionary solution).
As an example, I'm going to be much better at making money doing software development than I would be a politician trying to fight climate change. I can then use some of the money I make at work to donate to political campaigns that support the fight against climate change.
If I'm being honest, this feels like an excuse to some degree. But, I think it's worth considering that most of us may be more useful by indirectly contributing (via dollars) to the solution than directly.
