Enough individual action can create a political climate that enables an appropriate governmental response. For example, when every home has roof-top solar, everyone is riding bikes or scooters, growing food locally, not flying, etc. It's harder for politicians to create new subsidies for coal mining, or tax concessions for airlines. Instead they will be more likely to pass carbon fee and dividend schemes or similar. On the other hand, while everyone continues to drive around in SUVs, buy cheap goods from China, long haul flights all the time, and food from the other side of the world, it's easy for politicians to maintain the status quo. Individual action can't solve climate change by itself. But it is still meaningful and necessary. Our actions influence the actions of others around us, and we can redefine "normal" for our society. Studies have shown that somewhere between 10 and 20% of a population acting in a new way are enough to shift the opinions of the remaining majority.
