Marx’s treatise on the relationship between human beings and nature contains his abundant ideas of human ecological needs.The present ecological crisis which has destroyed the root to satisfy the human’s ecological needs is resulted from three aspects:the first is the erroneous environmental ethic idea,the second is the environmental egoism and ecological colonialism and the third is the diversification and antagonism of human needs and interest groups.The following are the basic solutions to the ecological crisis:firstly,we should cultivate correct ethic ideas to remove the environmental egoism and ecological colonialism; secondly,we should develope new and high technology; thirdly,we should respect and follow the laws of nature and take the scientific developing route for the wellbeing of the whole mankind; fourthly,we should cultivate the human’s unalterable communism faith to induce and encourage the people to strive for the realization of communism.
