  Pero, ¿qué es un Océano? U n océano es una enorme masa de agua salada que representa un importante ecosistema para el equilibrio ecológico de la Tierra y que constituye el  71% de la superficie terrestre , gracias a los 360,132,000 km² de su extensión. Y,  ¿cuántos océanos existen? Lo que cubre gran parte de la superficie de la Tierra, es en sí, un solo océano. Es decir, una sola masa de agua. Para un mejor estudio, el hombre dividió esta enorme masa en 5 partes de acuerdo a su ubicación geográfica. Por ello, la expresión “los océanos”, es correcta. Importancia de los océanos *Absorben entre un 25 y 30% del dióxido de carbono emitido a la atmósfera, por lo que Equilibran el clima de toda la Tierra. *Representan numerosos ecosistemas para diversas formas de vida animal, vegetal, bacteriana, protista y fúngica. *Son hogar para miles de especies, conocidas y aún desconocidas. Existen aproximadamente 250,000 especies conocidas, pero se cree que puedan haber 750,000 más. *Proveen fuentes

Almost 11,000 elephants killed by poachers in a single park

English article
Surveys in Gabon's Minkebe National Park have revealed rare and hard data on the scale of the illegal ivory trade over the last eight years: 11,100 forest elephants have been slaughtered for their tusks in this remote protected area since 2004. In all, poachers have cut down the park's elephant population by two-thirds, decimating what was once believed to be the largest forest elephant population in the world.

"Without a global commitment, great elephant populations will soon become a thing of the past," the president of the Wildlife Conservation Society (WCS), Cristián Samper, said. WCS helped conduct the surveys along with WWF and Gabon’s National Parks Agency, the ANPN. "We believe that elephants can still be saved—but only if nations greatly increase their efforts to stop poaching while eliminating the illegal ivory trade through better enforcement and reduced demand."

While Africa's savanna elephants (Loxodonta africana) have often been the focus of media reports on poaching, it's the continent's forest elephants that have been hit hardest. Recent studies have argued that Forest elephants (Loxodonta cyclotis)—which are smaller and sport straighter tusks than the more widely known savannah elephants —are in fact a distinct elephant species, and not just a subspecies. Forest elephants are found largely in the Congo, where political instability, poverty, corruption, and a lack of law enforcement have made poaching even easier.

In 2011, a camp in the buffer zone of Minkebe containing 300 gold miners exploded to 5,000 people, including miners, poachers, as well as arms and drug dealers. Officials believe that 50-100 elephants were being killed every day during this time.

Gabon has since upped its efforts to combat the runaway poaching, including recent seizures and arrests.

The illegal ivory trade has exploded due to demand from China and parts of Southeast Asia. A recent investigative report in National Geographic, entitled Ivory Worship, argued that much of the ivory is being made into religious handicrafts, particularly for Catholics and Buddhists. Demand from East Asia is also decimating rhino populations, which are poached for their horns.

Larger than the U.S. state of Delaware, Minkebe National Park is also home to Western lowland gorillas, chimpanzees, mandrills, bongos, dwarf crocodiles, leopards, and African golden cats.
