But I ask again - for what? What big change are they hoping to accomplish?
It is completely possible to achieve zero emissions in six years time. It is not likely. It is not easy. But it is possible.
Since we're talking about Pankhursts, let's compare our current government to Asquith's in 1914. They also faced a crisis - a war with Germany. So what did they do? They passed a law in 1916 making it illegal for any able-bodied unmarried man aged 18-30 to do anything except devote his entire existence to solving the problem. They mobilised, armed, fed and equipped an army of literally millions, who spend four years fighting.
1.8 million British men died. Huge numbers more lost their physical and mental health. The entire social structure of British life was changed forever. Thousands of women left their homes and jobs and took on the work that those men had left. The daily lives of everyone in the country was completely changed for four years. We had rationing. Food shortages. Unheated houses. And we achieved our aim.
The current crisis is far more serious than the risk of losing a war. I agree with pp that the rhetoric of XR is overdramatic. I don't think we're facing inevitable extinction or societal breakdown. But I think it's possible. Mainstream science says that millions of people will die, whole countries will become uninhabitable (though probably not Britain), and war, famine and natural disasters will become more common. Those things are beginning to happen now.
If we treated this big emergency with the same seriousness as we treated the much smaller emergency of WW1, we could be carbon neutral in 2025. Do I think we're plausibly going to? No. I don't think XR do either. But I think by demanding it, they're going to get something much closer to the level of response that we need.
This isn’t a human right that is being withheld
Declaration of Human Rights says that "Everyone has the right to a standard of living adequate for the health and well-being of himself and of his family, including food, clothing, housing and medical care and necessary social services." Our government is failing to even meet the requirements of the Paris Climate Change Agreement, which most climate scientists agree is completely inadequate. That's directly trampling in the human rights of entire nations.
