Who owns all national parks. If the U.N. most of parks who rest?

National parks are primarily owned and managed by the respective national governments of the countries in which they are located. There is no single entity that owns all national parks globally. Each country has its own national park system, and the management and administration of these parks may vary depending on the policies and regulations set by the respective governments.

The United Nations (UN) does not own national parks. The UN may play a role in promoting conservation efforts and encouraging countries to establish protected areas, but it does not directly own or manage national parks.

In summary, national parks are owned and managed by the countries in which they are located, and there is no single global entity that owns all national parks.
