Operative word you. Individual action was a deliberate red herring constructed by the FF industry propaganda machines half a fucking century ago, because they knew who the actual significant contributors to the problem were.

I do agree that real change takes political power. You need things like tax breaks for people who use public transit, congestion pricing, taxing airports more, banning ads for SUVs, requiring electronic devices to be repairable, etc... These actions would be far more efficient than any individual action. Sure.

But political power isn't enough. Look at what just happened in Canada.

Justin Trudeau banned oil tankers off the coast of British Columbia and he tried to ban single use plastics. He faced outraged reactions.

Some angry politicians were publically taunting him on social media and sued his government :

A guy literally campaigned on defending plastics and slashing the (tiny) tax on carbon.

See what happened? The guy was the Prime Minister. He tried some small changes. He faced brutal political backlash. Why? His people weren't ready.

Change starts with individuals. Only when you reach a critical mass of individuals can you start trying to push for policy changes.
