Brazil has been nominated for two locations in the Seven Wonders of Nature competition, in which people can vote for the greatest wonders of the natural world. The Amazon and Iguaçu Falls were chosen amongst thirty total natural wonders from around the world. They are competing against the Grand Canyon, the Great Barrier Reef, the Dead Sea, and Mount Kilimanjaro, amongst others.

The top thirty finalists were chosen by a panel of experts based on five factors: unique beauty, diversity and distribution, ecological significance, historical legacy, and geo-location (allowing an equal amount of finalists from the seven continents).

You can vote for your favorite seven wonders of nature on the official website, though the results won’t be announced until 2011. You can vote on the website or by phone, and the site will release the latest ranking of the most voted sites next week.
