Yet again… Shell doesn’t give a toss.
No matter what you do Shell et al. will carry on doing their thing as long as there is money in it.
To achieve anything you have to get people,. i.e. you, me, Mark Zuckerberg, Elon Musk, Putin, Biden, Xi, Uncle Tom Cobbley and all to change and in turn make Shell, et al. change because there is no money in doing the bad things.
How do you do that? I don’t know. I suspect it’s not possible but then I’m less optimistic than Just Stop Oil, Extinction Rebellion, etc.
They seem to think that getting rich and “important” people to realise that this affects them might help.
So one of the things they do is disrupt events that rich and important people go to and/or like to tell themselves are important to them, like “Art” and posh sport like Wimbledon.
This of course does not preclude doing other things.
A protest group can do more than one thing. If you’ve got ideas, they’d love to hear them.
