 Furthermore, Kovel quotes Trotsky, who believed in a Communist "superman" who would "learn how to move rivers and mountains".Kovel believes that, in Joseph Stalin's "revolution from above" and mass terror in response to the early 1930s economic crisis, Trotsky's writings "were given official imprimatur", despite the fact that Trotsky himself was eventually purged, as Stalinism attacked "the very notion of ecology ... in addition to ecologies".Kovel adds that Stalin "would win the gold medal for enmity to nature", and that, in the face of massive environmental degradation, the inflexible Soviet bureaucracy became increasingly inefficient and unable to emulate capitalist accumulation, leading to a "vicious cycle" that led to its collapse.
