Status
Improving our status in society is one of our strongest motives, probably because status increased the odds of reproduction. Status is what we strive for. Lack of status causes stress, which reduces learning ability. Money or power would seem mere means to achieve status. Effective ways to influence civilization would have to account for our longing for status.
Status is currently closely linked to the consumption of resources (e.g., property, travel).
Once most people realize that consumption prevents future civilization, it will reduce status. We will then reduce consumption and look for ways to live without consumption as a result. Communicating the need to find ways to continue without consumption and making consumption of resources socially unacceptable thus helps to create conditions for civilization to continue.
