The planet Earth stands out in the known Universe for its wealth of water, biodiversity, and living species, including humans. Water is majorly relevant to all living beings; in some organisms, up to 90% of their body weight comes from water. Up to 60% of the human adult body is water. In the same way, our planet is covered up to 70% by water. With its natural and anthropic cycles, water is an essential element in our planet, and any alteration in terms of its quantity and/or quality can affect the health of all interconnected elements and living species. The water resource is not the sole element crucial for the health of people, animals, and the natural ecosystems; all environmental resources are interconnected and participate in the health of living species and ecosystems. These aspects are generally approached by civil and environmental engineering or, more in general, by environmental scholars.If from one side it is reasonably verified that we live under one planet and the interconnections between the different elements are generally known; however, the environmental engineering science and the health matters of humans and animals are fundamentally not well integrated, which is of concern at present days. "One Health" is an integrated approach between three main spheres of knowledge (Figure 1): human health, animals' health, and living environments or environmental health (Ash, 2019;Zinsstag et al., 2018). The latter component is often neglected, as evident from the various sources where it is not mentioned strongly (Essack, 2018). As it is known, environmental issues seem to be a significant index towards accomplishing UN Sustainable Development Goals (SDGs). The 17 SDGs illustrate how to develop a sustainable and healthy environment for all living beings (Brito, 2012;Griggs et al., 2013), all highly interconnected with the "One Health" approach.One Health is not a new approach, but it is more recently put into action by FAO and WHO because globalization and relative movement of people, animals, and natural products have exponentially increased from international travel and trade. As a result, diseases can spread quickly across borders around the globe, and the most evident indicator of this issue is the current COVID19 pandemic.
