"We" aren't failing at controlling climate change. That's because "we"- the actual people- have little power to make the decisions necessary to fix things.
Instead, this is being done to us.
The small group of sociopathic billionaires driving the destruction would like nothing more than for us to blame ourselves for what they are actively doing to us, absolving them of blame.
So stop saying "we" are failing. We're not. We're fine.
