Panama's tropical environment supports an abundance of plants. Forests dominate, interrupted in places by grasslands, scrub, and crops. Although nearly 40% of Panama is still wooded, deforestation is a continuing threat to the rain-drenched woodlands. Tree cover has been reduced by more than 50 percent since the 1940s. Subsistence farming, widely practised from the northeastern jungles to the southwestern grasslands, consists largely of corn, bean, and tuber plots. Mangrove swamps occur along parts of both coasts, with banana plantations occupying deltas near Costa Rica. In many places, a multi-canopied rain forest abuts the swamp on one side of the country and extends to the lower reaches of slopes on the other.
Panama is bounded to the north by the Caribbean Sea (an extension of the Atlantic Ocean) and to the south by the Pacific Ocean. It has an elongated S shape, with its Caribbean coastline stretching some 800 miles (1,290 km) and the Pacific coast some 1,060 miles (1,700 km); however, a line drawn from the Costa Rican frontier in the west to the Colombian border in the east would extend only 480 miles (770 km). The shortest distance across the isthmus is about 30 miles (50 km), from the mouth of the Nergalá (Necategua) River, which flows into the Gulf of San Blas on the Caribbean shore, to the mouth of the Chepo River on the Pacific coast. Nearly as narrow is the portion of the isthmus traversed by the Panama Canal.
The Panama Papers are an unprecedented leak of 11.5m files from the database of the world’s fourth biggest offshore law firm, Mossack Fonseca. The records were obtained from an anonymous source by the German newspaper Süddeutsche Zeitung, which shared them with the International Consortium of Investigative Journalists (ICIJ). The ICIJ then shared them with a large network of international partners, including the Guardian and the BBC.
