Elimination, or removal, refers to the process of getting rid of something unwanted or unnecessary. This can apply to various contexts, such as waste management, where garbage is removed from homes and public spaces to maintain cleanliness and hygiene. In biology, elimination involves the expulsion of waste products from the body, ensuring that organisms remain healthy. In a broader sense, elimination can also refer to the removal of obstacles or challenges in different fields, such as sports or business. For example, a team may eliminate competitors in a tournament, while a company might eliminate inefficiencies to improve productivity.
