Most people know of the Karen people from television documentaries, magazines and encyclopedias as the “long-neck” or “giraffe” tribe. But the women who wear these brass rings on their neck belong to a sub-group of the Karen known as the Padaung. Whatever the origin of the custom one of the more common reasons it continues today, particularly in Thailand, is tourism. Although the Padaung have migrated to Thailand in only the last ten years, they have become the most popular “attraction” for hill-tribe trekking tourists. Some have written of this as exploitation of the Padaung; many westerners liken the experience of visiting one of these villages to visiting a human zoo. Some tour operators in Thailand now refuse to take tourists into such villages, while some tourists boycott those operators that do.

(UNESP) Status of same-sex marriage

South America

Argentina

The Autonomous City of Buenos Aires (a federal district and capital city of the republic) allows same-sex civil unions. The province of Rio Negro allows same-sex civil unions, too.

Legislation to enact same-sex marriage across all of Argentina was approved on July 15, 2010.

Brazil

A law that would allow same-sex civil unions throughout the nation has been debated. Until the end of the first semester of 2010 the Supremo Tribunal Federal had not decided about it.

Colombia

The Colombian Constitutional Court ruled in February 2007 that same-sex couples are entitled to the same inheritance rights as heterosexuals in common-law marriages. This ruling made Colombia the first South American nation to legally recognize gay couples. Furthermore, in January 2009, the Court ruled that same-sex couples must be extended all of the rights offered to cohabitating heterosexual couples.

Ecuador

The Ecuadorian new constitution has made Ecuador stand out in the region. Ecuador has become the first country in South America where same sex civil union couples are legally recognized as a family and share the same rights of married heterosexual couples.

Uruguay

Uruguay became the first country in South America to allow civil unions (for both opposite-sex and same-sexcouples) in a national platform on January 1, 2008. Children can be adopted by same-sex couples since 2009.
