So they prorest... The police use fuel to reach the protest, add the cost of their time reporters use fuel to observe the protest are the cost of their time, just a guess but that adds up to the equivalent environmental damage of not insulating a fair number of homes, Add the additional fuel cost to everyone stuck in the traffic queues, Wouldn't their time be better spent working on a social media campaign, getting some celebs on board, a few footballers maybe....it's the way you promote change, these dinosaurs are campaigning indirectly for their own extinction.
