![]() | CREA - Saving Tropical Ecosystems Google Tech Talks May, 15 2008 ABSTRACT Michael will talk about the work that his organization CREA is carrying out in Panama to conserve endangered tropical forests. Specifically the talk will deal with the link between human poverty and environmental degradation and how social justice is key to the solution. In his presentation Michael will discuss how CREA is taking a leading role environmental conservation through the implementation of innovative programs and initiatives that the organization undertakes. Speaker: Michael Roy (PhD) Michael is an accomplished conservation geneticist having obtained his PhD from London University and thereon working in academic institutions in UK, Denmark and the US before being made a tenured senior lecturer of zoology at Otago University, New Zealand. He has undertaken biological research on a wide variety of terrestrial and marine organisms and has generated over 40 international research papers. While working on sabbatical in Panama as a conservation biologist with the Smithsonian Tropical Research Institute in 2002 he came to the stark realization that the knowledge gained by his research and that of others was not being conveyed to the people that most needed it. At that point he made the bold decision to leave his successful career as an academic and dedicate himself to creating a grass-roots organization that could really making a change. That organization became known as Conservation through Research Education and Action: CREA. In 2005 CREA became a 501 c 3 organization whose mission is to conserve tropical rainforests through the building of sustainable livelihoods for rural communities based on the principles of science, education and social justice. Since then Michael has been working full time with CREA. |

![]() | Coral Reef Ecosystem http://www.myspace.com/acorvettes All living things require energy to carry out life functions such as growth, movement, and reproduction. For nearly all ecosystems—diverse collections of species that interact with each other and their physical environment—the major source of energy is the sun. The flow of energy tends to follow the same basic pattern whether the ecosystem is a tropical rainforest or a coral reef. To portray the transfer of energy through an ecosystem, ecologists use simple models called food chains. Organisms can be organized into different trophic levels, or positions in a food chain; organisms at higher trophic levels feed on those at lower levels. |

![]() | DEFORESTATION-Degradation of humid tropical forests CAUSES OF THE DEFORESTATION IN THE WORLD Climatic hazards or natural catastrophes are pratically independent from the actions of the man. However, the worries concerning eventual future climatic changes, due to the consequences of green house gases from industrial pollution are going to grow. It is sufficient to study here not the ways of fighting these aggressions, but those measures to take before forestry stands are subjected to these events. Forests are submitted more than any other terrestrial ecosystem to climatic hazards, due to the duration of their maturity, wich can take up to 200 years. In such a period the number of climatic hazards can be great. The importance of human factor The main causes of contemporary fires and anthropogenic : This is the case with the recurrent fires in the European Mediterranean zone, or those fires provoked in tropical humid zones, which have their goal the clearing of land for agriculture. In dry tropical zones with mixed broadleaved forests and rich undergrowth, human populations have always used fire to make way for grazing and agriculture. In Europe, figures gathered by the FAO permit one to establish the area of forest burnt annually between 1980 and 1988, i.e. some 585.000 ha. During the same period North America lost some 3.5 million hectares of forest to fires. That percentage attribued to human causes being around 97% in Europe, 91% in the United States and 66% in Canada. Very little is known concerning the equivalent information for the entire world. The total wooded surface touched by fire annually is around 10 million hectares, which represents some 0.3% of the total world forested area. However the impact of these fires is more important than this small percentage suggests. In fact, in the zones where the frequence of fires is high, the destructive character of such fires is worsened by the fact that forest stands do not have the time to reconstitute themselves between the passage of two consecutive fires. Fire has always been an element present in many forestry ecosystems. Natural causes of fire exist such as lightening and volcanic eruptions. The area subjected to natural fires has been very important and can cover millions of hectares. However the lapse of time is generally long between successive fires, permitting the ecosystem to recover and reconstitute itself. Large fires have always ravaged the surface of the earth.

![]() | AIR BOAT RIDE - EVERGLADES, FLORIDA Everglades National Park is a national park in the state of Florida. The largest subtropical wilderness in the United States, it contains the southern 25 percent of the original Everglades marshland region of southwestern Florida. Unlike most other U.S. national parks, Everglades National Park was created to protect a fragile ecosystem instead of safeguarding a geographic feature. Thirty-six species designated as threatened or protected live in the park, including the Florida panther, the American crocodile, and the West Indian manatee. Protecting the largest U.S. wilderness area east of the Mississippi River, the park is the most significant breeding ground for tropical wading birds in North America, and contains the largest mangrove ecosystem in the western hemisphere. More than 350 species of birds, 300 species of fresh and saltwater fish, 40 species of mammals, and 50 species of reptiles live within Everglades National Park. All of southern Florida's fresh water is recharged by the park, including that of the Biscayne Aquifer. Crocodiles coexist with alligators in Everglades National Park, the only place in the world where they do so naturally. An alligator is a crocodilian in the genus Alligator of the family Alligatoridae. The name alligator is an anglicized form of the Spanish el lagarto ("the lizard"), the name by which early Spanish explorers and settlers in Florida called the alligator. There are two living alligator species: the American Alligator (Alligator mississippiensis) and the Chinese Alligator (Alligator sinensis). ________________________________ O Parque Nacional Everglades é um parque nacional norte-americano localizado na porção meridional dos Estados Unidos, no estado da Flórida. É a o única área sub-tropical preservada da América do Norte.O parque possui uma flora tanto sub-tropical, como tropical, e é muito conhecido pela sua grande quantidade de pássaros, além dos jacarés e crocodilos. Os jacarés ou aligatores são répteis da família Alligatoridae da ordem Crocodylia. São animais muito parecidos com os crocodilos, dos quais se distinguem pela cabeça mais curta e larga e pela presença de membranas interdigitais nos polegares das patas traseiras. Com relação à dentição, o quarto dente canino da mandíbula inferior encaixa num furo da mandíbula superior, enquanto que nos crocodilos sobressai para fora, quando têm a boca fechada. |
![]() | The World's Greatest Treasure House http://amazongifts.org Honoring Our Connection with Nature Imagine a portion of real estate almost the size of the United States and you get an idea of the immensity of the Amazon Rainforest. Imagine a virgin tropical environment hundreds of miles from the nearest road or source of pollution. Think of the Rainforest soil, rich in minerals and trace elements as the forest continuously recycles in a virtually closed ecosystem. Imagine over 200,000 species of plants thriving in this tropical paradise. Consider that approximately 40% of modern therapies and medicines are derived from just 2% of these Rainforest botanicals. Think about the life-saving research that still needs to be done. The World's Greatest Treasure House Clearly we are looking at our planets greatest natural treasure house home of the highest concentration of nutrients and life energy on earth. It plays a key role in maintaining global health and climatic stability. Every person in the world is a direct or indirect beneficiary of the Amazon Rainforest. For the sake of all mankind, the Rainforest must be preserved. |
