I love that analogy. No, you're not going to personally save the world by reducing your carbon footprint. But you know what you are going to be? One leaf on a tree in a forest, making that little bit more oxygen that helps collectively make the world a better place.
And that's worth doing. Especially if you can encourage other people to be leaves too.
It might've been invented by Big Oil, but if you keep giving money to Big Oil to buy fossil fuel you're at least partially responsible for the carbon emissions released by burning that fuel.
People have trouble with the concept of partial blame, they want to feel innocent. Black and white thinking, low-resolution ethics.
It's a necessary suppression to underpin individualist ideologies, I think.
Nevertheless, remember that the 'footprint' decisions of one oil exec outweigh the decisions of thousands or millions (or billions if you include descendants) of ordinary folk. But we do also outnumber them to that extent, so we have adequate power collectively.
