Environmentalism is a belief and a strong desire to rebuild the relationship between man and nature. To realize this desire, it is necessary to establish a sense of natural community, that is, to change the role of human conquerors in the community into this Ordinary member of the community. It implies respect for each member, as well as respect for the community itself. Only with such a sense of morality can one be able to exercise his rights in the community. I feel that I have an obligation to this community, which depends not only on the scientific understanding of the nature of nature, but also on the feelings for nature built on the basis of understanding. "This" in the last sentence of this text refers to:. ['Love for nature.', 'Establishment of a sense of natural community.', 'Desire to rebuild the relationship between man and nature.', 'Obligations to the natural community.']
