negligible in their contribution to these floods. A number of sources point to the misuse of hydroelectric dams as a cause of the floods. Hydroelectric plants in the dams of Tabasco share the production of electricity with newer, private, more expensive gas plants. Investors complained that government owned plants cover most of the production of the electricity, lowering the price, and have put pressure on the government to lessen production on hydroelectric plants in order for them to sell more energy and raise their profit levels. This allegedly led to the dams retaining more water than they should have done. Impact Tabasco was subject to heavy rain in late October and early November 2007, causing widespread flooding. As much as 80% of the state was under water. At least 20,000 people were forced to leave their houses in the search of emergency shelter. Over 1,000,000 residents have been affected. The 2007 Tabasco flood not only destroyed many family houses and took away people's belongings, but also affected theaters, libraries, artistic schools and museums. One of the buildings affected was the house of the poet Carlos Pellicer Cámara, which ended up under the water. The house where the poet lived his childhood is located in Narciso Sáenz 203, in the center of Villahermosa, Tabasco. Another historical house affected is located at 620 Calle Lerdo de Tejada, in Villahermosa, close to Carlos Pellicer's house. The house once was occupied by José Gorostiza, the author of the Muerte sin fin poem, his brother, the dramatist Celestino Gorostiza, and the man of letters Andrés Iduarte. Economic impact at national levels will be insignificant. There is important damage in the fields which is causing increases in banana and cacao prices. The flood in Tabasco will not affect the economy in Mexico as much. Guillermo Ortiz Martínez, president of the Banco de México (the central bank), agrees that Mexico will not have excessive inflation because of the Tabasco flood. But some prices of products will increase such as banana and cacao. The General Peasant Confederation informed that because of the flooding, 100% of the harvests are lost. This represents an economic damage of US$480 million. President Felipe Calderón has sent seven thousand and five hundred people to help people in Tabasco. This is because of the major damage to roads, houses, and farms. The flood destroyed agricultural production in the state of Tabasco, the largest producer
