Banning refers to the act of prohibiting or restricting certain activities, behaviors, or items. This can occur at various levels, including local, national, or international, and is often implemented through laws or regulations. Common reasons for banning include protecting public health, safety, or morals, as well as addressing environmental concerns. Examples of bans include the prohibition of certain substances, like drugs, or the restriction of specific practices, such as smoking in public places. Bans can also apply to products, like plastic bags, to reduce environmental impact. Enforcement of bans typically involves penalties for non-compliance.
