OUR global environmental crisis is widely understood to be reaching a crucial moment; the danger signals are flashing almost daily. Yet a certain complacency follows the many catastrophic climate events attributable to a critically injured environment. People talk easily of a climate Armageddon, while maintaining business as usual.

Is this fatalism? Are there onerous sacrifices necessary to save the planet? Are there insurmountable obstacles to finding solutions? Are we beyond the point of no return? These questions need urgent answers.

The truth is that some leftists have been addressing these problems and ringing the alarm for decades. But some of us, though recognising the crisis, have paid only lip-service to its solutions, neglecting to apply the unique perspective that Marxism could bring. Looking at the crisis through the lens of class and exploitation surely offers a deeper understanding than the sensationalism and superficiality of the capitalist media and their punditry.
