It seems like the biggest impact a person has on the world is the way they treat people, especially people they don't agree with.
There seem to be three primary options regarding climate change:
1) change your lifestyle
2) make someone else change theirs
3) make better technology
Option two seems to be the default based on average home sizes, commercial flights, food waste from dining out, and iPhone sales.
Technology optimists choose option three.
The outliers choose option one.
