"The Shell" is a term that can refer to various objects, but it often describes the hard outer covering of certain animals, such as snails and tortoises. These shells serve as protective barriers against predators and environmental hazards, allowing the creatures to survive in their habitats. In a broader context, "The Shell" can also refer to the Shell Oil Company, a global group of energy and petrochemical companies. Founded in the 19th century, it is known for its involvement in oil exploration, production, and refining, as well as renewable energy initiatives.
