Consider placing an A4 sized page of general info in the lunchroom. No one will pick it up but many will read it. Replace it occasionally with a new design that isn't AI generated.

To start a discussion, perhaps try from a personnal perspective which can be an honest story of transition from ignorance to understanding. The awareness of these issues is coming to the collective concious light, albeit gradually, and we are all learning the impacts as they're occurring.

"AI is an awesome tool but I had no idea it caused so much pollution. I watched a story about X's platform and their Grok AI centre in Memphis. Its causing so much harm to the people and the local environment, I had no idea! I was shocked and sadened to see these peoole suffering. We might need to start thinking about responsible use of AI to limit the human and environmental impact, especially if that's what our planet needs right now."
