Protected areas or conservation areas are locations which receive protection because of their recognized natural, ecological and/or cultural values. There are several kinds of protected areas, which vary by level of protection depending on the enabling laws of each country or the regulations of the international organisations involved. The term "protected area" also includes Marine Protected Areas, the boundaries of which will include some area of ocean, and Transboundary Protected Areas that overlap multiple countries which remove the borders inside the area for conservation and economic purposes. There are over 161,000 protected areas in the world (as of October 2010)[1] with more added daily, representing between 10 and 15 percent of the world's land surface area.[2][3][4] By contrast, only 1.17% of the world's oceans is included in the world's ~6,800 Marine Protected Areas.[5]
