Abstract: With the global ecological problems becoming more and more serious, the Ecological Marxist theorists represented by Forster, use materialist and dialectical ecological thinking to criticize the social new metabolic fracture phenomenon under the rule of capital logic, and reflect on the binary opposition, i.e. exaggerating people's absolute subjectivity and negative reflection of subjectivity. The author tries to find a realistic way to overcome the theoretical dilemma of Western capitalist social subjectivity under the ecological crisis, but fails to find a realistic way beyond the capitalist mode of production, which leads to the theoretical limitation of its subjectivity. In the new era, the socialism with Chinese characteristics not only puts forward the overall plan of "five-in-one", but also creates more material wealth by relying on the construction of socialist market economy. On the basis of public ownership as the main body and the coexistence of various ownership systems, it condenses the consensus of people's interests at all levels, and implements the people-oriented social development concept of all for the masses and all relying on the masses, so as to serve the people. Thus a realistic way could be found to overcome Forster's subjective theory dilemma and provide valuable practical experience for promoting the construction of global ecological civilization.
