Thirukkural, global literature does not only talk about human behaviours which are to be glorified. It also proposes bright cut ideas about the relationship between humans and nature. The attention of the modern world is on environmental issues. The fast developments due to science and technology resulted in destroying nature. Due to industrial-based products and for the sake of the sophisticated life of the modern man, we left the nature for destruction. And now humanity faces the consequences. It is a general truth that the literature reflects the social issues of that time of its outcome. One can notice that the recent creative literature of Tamil talks about environmental aspects of the globe and the local areas. Thirukkural also deals with the issues of nature and it proposes the ideal relationship between man and nature, which is the concern of this paper. Thiruvalluvar says that the whole world depends on water. All the activities in the world cannot be possible if the rain fails. All the activities of living creatures, including humans, depend on water. Start with food production and leading to every activity are depends on rain. So Tiruvalluvar concludes that the relationship between humans and nature depends on water i.e. is rain. The paper concludes that the concept of Thiukkural towards nature is the dependency of humanity.
