Animales en Extinción/Endangered animals
Venezuela uno de los países con mayor diversidad biológica, hoy es lamentable el aumento de la cifra de animales en extinción, debido a la intervención del hombre. Hasta 1974 se habían extinguido 68 especies de mamíferos, 130 especies de aves y 28 especies de reptiles. Más de trescientas especies animales y un número indeterminado de especies vegetales corren el riesgo de extinción definitiva, uno de esos animales es la Tortuga Verde que estaremos investigando a continuación.
[Venezuela one of the most biologically diverse countries, today is regrettableincrease in the number of animals in extinction due to human intervention.Until 1974 they had extinguished 68 species of mammals, 130 species ofbirds and 28 species of reptiles. Over three hundred species of animals andan unknown number of plant species at risk of ultimate extinction, one ofthese animals is the Green Turtle and then we will be investigating.]

Distribución:
Es la tortuga más abundante del Mar Caribe. En Venezuela puede encontrarse en el Archipiélago de las Aves, en los Roques. La mayor concentración se encuentra en Isla de Aves, donde cerca de 500 hembras desovan todos los años, siendo después de Tortuguero, la segunda colonia reproductiva más grande en el Mar Caribe.
La Tortuga verde también se encuentra en aguas cálidas tropicales y subtropicales. Las hembras de tortuga verde solo van a las playas a depositar sus huevos en nidos tradicionales de arena, fuera de este hecho, la especie es totalmente marina.
[Distribution:
It is the most abundant turtle in the Caribbean Sea. In Venezuela can be found in the Archipelago of Birds, in Los Roques. The highest concentration was found in Bird Island, where about 500 females spawn every year afterbeing Tortuguero, the second largest breeding colony in the Caribbean Sea.
The green turtle is also found in warm tropical and subtropical waters. The female green turtle only going to the beaches to lay their eggs in sandy neststraditional, out of this fact, the species is fully marine.]

Amenazas:
La especie ha sido utilizada como fuente de alimento para las poblaciones costeras. Sin embargo, la razón principal por la que sus poblaciones se han reducido tan drástica mente es la comercialización de su carne, huevos, cuero, aceite y otros productos derivados. Igualmente los desechos tóxicos derramados en bancos de algas afecta severamente a los tortuguillos que de ellas se alimentan.
[Threats:
The species has been used as a food source for coastal communities.However, the main reason why their populations have declined so drasticallymind is the marketing of meat, eggs, leather, oil and other products. Equallytoxic waste spilled on seagrass beds is severely affecting the turtles that feedthem.]

"Es alentador reconocer la toma de conciencia sobre la protección de la Naturaleza,por organismos gubernamentales mediante la declaración de parques nacionales y la iniciativa privada mediante la protección de la fauna por los dueños de fincas y haciendas, y cría de especies en peligro de extinción para devolverlas y repoblar las zonas afectadas."
["It is heartening awareness on nature conservation by government agenciesthrough the declaration of national parks and private initiative through theprotection of wildlife by the owners of farms and ranches, and breeding ofendangered species to restore and repopulate the affected areas. "]
