= WHY ARE MARINE TURTLES IN DANGER? = 
 * 1) Over hunting before they were protected.
 * 2) Getting trapped in drift nets now that they are (although this was always a problem since man used nets for open ocean fishing).
 * 3) Disturbance (either intentional or accidental) at their breeding beaches.
 * 4) Plastic pollution in the ocean effects thousand of marine animals, causing them to sufocate aftter confusinghe pollutants with food.
 * 5) Some people illegaly collect turtle eggs for food.

= CLIMATE CHANGE EFFECTS ON MARINE ECOSYSYEMS = The ocean is the home of the marine animals! The impacts of climate change in marine life has a lot of consequences for our marine animals and it is also a big concern for scientists since climate change happens so fast that it will be impossible for marine animals to adapt to the changes. The increase of carbon dioxide and other greenhouse gases into the atmosphere are thought to be the main cause of climate change or global warming. As levels of greenhouse gases in the atmosphere increase, they trap heat which causes an overall warming of the planet as well as the oceean. Sea surface has changed dramatically causing the warming of the ocean. .

 = CURRENT EVENT = [|Marine Evolution]

This current event shows the work of the research team Marine Protected Area (MPAs) for threaten turtles. By keeping them safe from the threats of fishing.
= Marine Protected Area MPAs =

It refers to regions protected in which human activity has placed under some restrinction in the interest of conserving the natural environment according to Biology and Conservations.
= PROJETO TAMAR =

to the preservation of sea turtles' species threatened with extinction.
====Created in the 1980´s i t is now recognized internationally as one of the most successful experiences projetc in marine conservation and obligues as a model for other countries, especially because it involves coastal communities directly in the socio-environmental work .====

This is a video created by Ana Siller and Alexa Baumbach. It talks about Projeto Tamar and the biologist Paulo Lara and his role in PROJETO TAMAR.

= WHY SAVE TURTLES? = ====Sea turtles live in the open ocean and eat tiny animals that are found in floating seaweed concentration. The tiny sea turtles are preyed by fish, sharks and birds. Thus, they are an important part of the marine ecosystem. Their disappearance has caused many widespread effects in the open ocean and coastal ecosystems. ====

= OTHER THREATENED SPECIES =

Mediterranean Monk Seal
With less than 400 remaining, the Mediterranean Monk Seal is one of the rarest animals on the planet but due to increasing human populations they have since retreated to rocky sea caves virtually inaccessible by people. These caves are a much more dangerous place for the Monk Seal's young, and is a leading cause of deaths.

North Pacific Right Whale
It is consider the most endanger whale on earth; it is consider the preferred whale for hunters. for swimming slow and being near shore.

Giant Clam
This Giant Clam offers algae a safe home and access to sunglifht for their photosynthesis. Some scientist believe that some of larger ones are over 200 years old.They are also excellent for bio filters which means they extract nutrients.

Great White Shark
The biggest threat to the Great White Shark is humans who have long hunted it for its teeth, jaws, and meat. The white shark is famous for eating people because of the movie Jaws, however they eat fisht and marine animals.

Sea Otter
The Sea Otter was once hunted for its fur, this led to near extinction in the early 20th century, its numbers dropping below 2,000. Now protected by law, the Sea Otter is still endangered, but has made a recovery with over 100,000 currently alive.

Dugong
The Dugong is a vegeterian specie. It is now legally potected, however was a long target for hunters who desire its meat, oil, skin, teeth and bones. Its food sources are also in endangered which makes it hard for them to eat.

Steller Sea Lion
Though populations of the eastern Steller Sea Lion remain stable, the western one has seen a dramatic decrease in its numbers, falling 70 to 80%since 1970. While no conclusive has yet been found, one suspected cause is overfishing in the Gulf of Alaska reducing their food stocks.

= Scientists involved in the study = ==== Many people think that marine biologist spend their days swimming with the dolphins, sea lions or even whales in places suchs as: Sea World or other pools. However, as a discipline of biology, marine biology is the scientific study of bacteria, plants and animals that live in oceans and on their shorelines. Marine biologists apply their knowledge in a wide variety of biology and ecology related fields to study the living resources of the world's oceans and coastal seas as well as marine threatened species. Biologist look at everything and take care of their animals they also take of their food and changes in life. T hey also study the effects of light and causes of pollution on plant and animal life in oceans, and research endangered species of marine plants and animals and their habitats other work in environmental conservation, preservation and education, p roducing mathematical models to estimate the number and kinds of marine life in a specific place.====

===="Sometimes the turtle chooses to spawn in a place where the tide will flood later that nest. And because we want to retain the greatest possible number of turtles, we moved the nest above the highest high." - Paulo Lara====

Carole Baldwin (marine biologist)
marine biologist who specializes in tropical marine and deep sea fishes. She specializes in exploring the beaches and tide pools.

He is a marine biologist specialized in marine life. His professional experiences has taken him to the creation of a robot for the marine life.
