Introduction While we understand that natural forests are essential resources occurring on earth, human beings have continuously misused them to satisfy their short term needs. They have cut down trees to create a settlement, plant crops, produce industrial products, and construct structures among other needs. Although this tendency seems to satisfy human wants, it develops some linear effects resulting in human sufferings. The side effect of this deforestation, which has caused a lot of disability in the ecosystem, cannot be ignored anymore. As a result, this research seeks to identify the most important reason for the conservation of the forest by a human being. It aims at presenting a detailed rationale of taking care of the forests that can resonate with all people in totality. This rationale is based on analyzing the disadvantages of deforestation and the advantages of conservation. This ideology of presenting the two edges of forest conservation, which include the shortcomings alongside the benefits, can provoke people to retaliate from abusing the forest and taking endorsing conservation. Enthymeme I strongly believe that forests are pillars of sustainable development. The concept of sustainable development argues that development should encompass three aspects. These aspects include environmental awareness, economic growth and the sociology of human beings. It contends that developments should not sacrifice the sociology of people and the environmental stability of the surroundings. It adds that a sustainably developed system is equitable, bearable and viable implying that the development is not oriented to a single aspect of life. The concept of sustainable development will form the basis of this research meaning that we shall focus on the environmental, social and economic reasons for conserving the forest. Consequently, the research will present a holistic approach that does not disenfranchise any aspect of development. Environmental Reasons Source of Rain Water Rainwater, which is the main source of surface water, is an essential component of an environmental factor that human beings need for survival. Besides being the main source of surface water, rain is a component of the hydrological cycle that develops stability in the ecosystem. These two aspects of rain make it an inevitable environmental factor. In that light, we understand that trees release water in the form of humidity forming clouds which fall in the form of rain. This implies that the presence of trees increases the likelihood of receiving rainfall frequently. This condition is evident in the Amazon forest, which receives rainfall throughout the year, due to the thick forest comprising of the indigenous forest (Salati & Vose 133). On the other hand, the lack of forest cover leads to gradual desertification of originally arable land resulting in real deserts. This means that continued deforestation can result in lack of sufficient rain that in turn lead to desertification. As a result, we conclude that the conservation of forest is not only a role but also a mandate for all human beings in their capacity. Failure to conserve the forest will result in unsustainable development that seeks to develop economically only. Creating Biodiversity Animals and plants are created in a manner that enhances the self-sustaining system of biodiversity. Biodiversity is the harmonious co-existence of flora a
