Abstract: The subject of fluid mechanics, which deals with both static and dynamics fluids, is the pillar that supports the planetary system, all living things, and also the inanimate global economy as it covers not only the planetary movements, but also handles nearly every facet of life on the planet, such as in breathing, blood flow, swimming, pumps, fans, turbines, airplanes, ships, rivers, windmills, pipes flow, missiles, icebergs, engines, filters, jets, sprinklers, plants, and other living organisms. This paper therefore x-rayed the critical role fluid mechanics plays in supporting human life and the planetary systems from medicine, meteorology, oceanography, hydrology, biofluids, and environmental fluid mechanics all of which deals with naturally occurring flows in human and in the environment. It is also the pivot upon which all forms of transportations are anchored from aerodynamics in aircraft and rockets to hydrodynamics in naval ships and submarines and therefore employs different models of fluid flow patterns. Fluid mechanics is also behind all forms of combustion systems, so also in agriculture and food production that involves irrigation, flood control, water supply, sewage disposal. It is also responsible for global energy and oil and gas operations. Recognizing its vast applications in all aspects of human life, this paper recommends continuous investment in research and development in the study of the various disciplines of fluid mechanics, especially biofluid, environmental and geophysical fluid mechanics. More research is also needed in computational fluid dynamics that can provide concise solutions to the problems of turbulence, since most fluids in life and at industrial scales occur under turbulence regimes.
