PROBLEM: (CNN) -- For the record, I'm not a leading fan of the economist Jeffrey Sachs. But even from the "away" team benches, you have to salute the audacity of his latest adventure. Sachs, director of the Earth Institute at Columbia University, has nominated himself to be president of the World Bank. He has launched a political campaign to win the necessary votes from governments worldwide. He has won the endorsements of eight governments and 27 members of the U.S. Congress. Nobody has ever seen anything like this before. While people do "campaign" for jobs as heads of international organizations, they usually do so from behind the scenes. Their names mysteriously begin to be mentioned in the columns of The Financial Times, Foreign Policy magazine and The International Economy, but they never admit on the record that they want the job, much less go on the road giving speeches and interviews asking for it.Economist Jeffrey Sachs is mounting an unusual public bid to lead World BankDavid Frum says typically the job is awarded by a U.S. president after secret selectionHe says Hillary Clinton is a more likely candidate for the job than SachsFrum: In age of growing democracy, can top posts be handed out in secrecy?

SOLUTION: Sachs' quixotic campaign for _ president won't change that reality, even in the unlikely event that he should somehow win.

PROBLEM: (CNN) The Hawaiian archipelago is in trash trouble. Vast amounts of trash have been washing ashore on the state's once-pristine beaches. The National Oceanic and Atmospheric Administration has been trying to keep critical parts of the ocean clear of marine debris, removing 57 tons of it from the Northwestern Hawaiian Islands in 2014. This area is a part of Papahanaumokuakea Marine National Monument, the largest conservation site in the United States. Despite the government agency's efforts, Hawaii continues to be plagued by trash, much of it plastic. Originally, there was speculation that Japan's devastating 2011 tsunami had brought a wave of debris to Hawaii's islands, but recent results from an aerial survey suggest otherwise.The ocean current is carrying vast amounts of marine debris onto Hawaii's shorelinePreviously, many thought Japan's 2011 tsunami caused an uptick in marine debris

SOLUTION: _ is recognized around the world for our beautiful beaches.

PROBLEM: Choking smog may make you splutter, but it doesn't come close to the terror of Martian 'vog'. Scientists have found evidence of acid fog caused by volcanic eruptions on the Red Planet that's capable of devouring rocks. Nasa's Spirit rover detected signs of acidic vapour that caused rocks over 100 acres on Husband Hill in the Columbia Hills of Gusev Crater on Mars to go usually bumpy. A similar phenomenon is seen on Earth in Hawaii, where it is dubbed 'vog'. Planetary scientist Shoshanna Cole, an assistant professor at Ithaca College, New York, used a variety of data gathered by the rover's multiple instruments in 2003 to study the exposure of ancient bedrock on the planet.Experts found evidence of acid fog caused by volcanic eruptions on MarsUsed data collected by Nasa's Spirit rover in Gusev Crater on the red planetRocks were made 'bumpy' and less crystalline by acidic weatherSimilar phenomenon is seen on Earth in Hawaii, where it is dubbed 'vog'

SOLUTION:
When the _ vog touched the surface of the rocks, it dissolved away some of the minerals, forming a gel, according to the theory.
