| The main contents in this dissertation start from the relations between human being and nature. Human being, which is in the nature, has two properties. They are natural property and social property. Human being exists in the nature, so it has natural property. At the same time, human being exists in the society, so it also has social property. That is to say, human being as a social group has consciousness, motive and activity. Therefore, we should abide by natural laws and respect nature when we exploit it. Or else, we are destine to be punished by nature. Marxism doesn't think that wealth springs from labor, but labor and nature. The relation between human and nature is that of human and society too, which is the same as zoology problem and social problem. So we think that Capital institution is the main reason of zoology crisis. Though socialism is up against environmental problem, we believe that we can solve it when our realizing communism in the future. Dialect, materialism and prospect opinions are the main characteristics of Marx and Engel's zoology opinions. At the end of this dissertation, we also discuss some basic ways about how to deal with environmental problems and Marx and Engel's value in zoology environment. |
