The comprehensive ecological crisis is an expression of the contradiction between the planetary boundaries of growth and the endless accumulation dynamics of capital.
The ‘treadmill’ of accumulation leads to a planetary overload and to an “overall break in the human relation to nature arising from an alienated system of capital without end.”
This ecological rift is the result of a social rift: the domination of humans over humans.
Sounds very similar to Bookchin. Interesting to hear that Marx said this also. But yes capitalism could be described as the domination of humans over humans.
