The major problem facing the planet earth in the 21st century is human intrusion into the dynamics of the planet earth and its ecosystems. This has generated other serious problems like global warming and other implied risks that threaten all life on the planet. However, these problems cannot be left at the margin of philosophical reflection. The argument of this article is that Phenomenology of Planet Earth Ontology is a Vital Stride towards Environmental Integrity and Conservation; it gives a better account of asymmetrical relationship between humans and the natural world. The article proposes a return to the planet earth whereby the earth should be considered as the Other-self to us humans and to other ecosystems with its own ontological significance that deserves respect, care and protection. We have to see ourselves not as superior to the natural world, but rather, as part of it together with the other entities constituting the whole world. We need to bring the earth back to rightfully serve its purposes of being a mother and home for all existing beings. The article raises candid philosophical issues about our comportment towards the environment and how respectively we can live together with it.
