The Interior Minister is a member of a Cabinet in a Government. The Minister of the Interior (also Internal Affairs or Home Affairs) has positions which vary between governments. It is more a product of the 20th century, so its powers aren't universal among countries.
In most nations, the Interior Minister is responsible for police or security. However, in some countries, an Interior Minister can be more in charge of Internal Matters, such as entry into the country (like the Israeli Interior Minister or the South African Minister of Home Affairs).
The Department of the Interior and its agencies are observing National Oceans Month throughout June 2007 with a variety of events and ongoing conservation activities around the nation.
The Department of the Interior (DOI) is the nation’s principal conservation agency.
Interior is a large, decentralized agency with over 80,000 employees and 180,000 volunteers located at approximately 2,400 operating locations across the United States, Puerto Rico, U.S. territories, and freely associated states.
The department is headed by a secretary appointed by the president with the approval of the Senate.
As the nation's principal conservation agency, the department has the responsibility of protecting and conserving the country's land, water, minerals, fish, and wildlife; of promoting the wise use of all these natural resources; of maintaining national parks and recreation areas; and of preserving historic places.
