The right approach for more extreme activism should at least be directly related to the awareness. Another user pointed out the jet painting. It’s a great example. Many people are not aware of the massive carbon emissions from private jet owners. It made global headlines, drove awareness of a specific part of the problem, and even briefly impacted emissions by grounding jets.

Stonehenge has nothing to do with climate change. The visitors that that day may even be soured on the topic due to the protest’s impact on their plans. It accomplished nothing but momentary infamy, and is ultimately discrediting to the cause.

I attend more organized protests. I always bring materials for education. It’s always a good idea to supply literature or QR codes to resources to help inform interested passers-by.
