Australia will create the most important marine reserve network of the world.

Australia will create the most important marine reserve network of the world. | BIOLOGY AND GEOLOGY | Scoop.it

The Australian goverment will create the largest marine reserve network. It would 3.1 million km2.

 

The goverment works in the responsible gestion of the marine areas and marine resources. They are really worried about the protection of whales, turtles and other endangered species. They will also expand the protection to the Coral Sea.

 

It´s a very good new for the world.

BP Petroleum Disaster

BP Petroleum Disaster | BIOLOGY AND GEOLOGY | Scoop.it

Following release of the US government's latest estimate, the Deepwater Horizon disaster is confirmed as the biggest ever accidental release of oil into the oceans.

It exceeds the 1979 Ixtoc I leak - also in the Gulf of Mexico. It's comfortably bigger than tanker releases such as the Torrey Canyon and Amoco Cadiz, and 20 times the size of the 1989 Exxon Valdez spill with which it is often compared.

Now that BP finally appears to have the flow under control.

 

What impacts are we talking about - on the coast, on the ocean surface, or the sea floor?

Which species are we including - fish, shrimp, insects, plants, birds, whales, turtles - or some combination of them all?

Are we looking long-term or short-term, local or regional - and are we to include or exclude impacts from the use of chemical dispersants and fires and the other containment measures?

Remember!!

Remember!! | BIOLOGY AND GEOLOGY | Scoop.it

I would like to remember that next week we start with the oral exposition of the collaborative works about World Network Biosphere Reserves.

 

Please prepare as good as possible the Role play that I gave you.

 

Thank you very much.

 

See you!

Failed in diet and sports.

Failed in diet and sports. | BIOLOGY AND GEOLOGY | Scoop.it

Spanish teenagers fail in nutrition and in fhysical activity. These are the results of a programme developed in 92 schools and high schools. The problems are focused in fruit and vegetable consumption, fish and dairy products.

 

The first part of the programme had been evaluating nutritional habits and sport habits of 2516 students. They have done a nutritional register and a sport register.

The results are clear: more than 98% of the students eat under 5 rations of fruit and vegetables  a day. Also the 23% said that never eat legumes.

 

The register also observe a higher consumption of soft drinksand pastries.

 

Another worrying fact is that 45% of the students don´t have breakfast daily.

Scientists Discover Thriving Microscopic Plant Garden Under Arctic Ice

Scientists Discover Thriving Microscopic Plant Garden Under Arctic Ice | BIOLOGY AND GEOLOGY | Scoop.it

Earlier this month, a team of NASA scientists revealed the presence of a thriving bloom of phytoplankton underneath three feet of ice in the Arctic - A phenomenonthat researchers say is as astonishing as finding a rainforest, in the middle of a desert.The discovery was made during a 2011 NASA sponsored expedition undertaken by some of the world's most prominent scientists. Called ICESCAPE (Impacts of Climate on EcoSystems and Chemistry of the Arctic Pacific Environment) its mission was to find ways to improve NASA's remote monitoring of the changes that are occurring in the Arctic ice pack due to global warming.

 

Led by Stanford Professor Kevin Arrigo, the team was conducting their research north of the Bering Strait, in the Chukchi Sea ice pack - An area of the Arctic not known to sustain life due to the thickness of the ice. So you can only imagine their surprise when their fluorometer, a measuring device used to gauge water content in algae, suddenly began lighting up fiercely. At first, they thought the device was emitting false signals.

 

While amazing, the reason behind this blooming garden is not so heartening. Scientists believe that the growth of this lush forest of the microscopic single-celled organisms can be attributed to the fact that sunlight is now able to penetrate through the Arctic Sea ice, a situation caused by global warming.

 

The researchers believe that if the current global warming trends continue, algae gardens will become a common occurrence, encompassing as much as 25% of the Arctic seas, within a few years. This is turn, will shift the Arctic ecosystem as we know it today - Benefiting some species while destroying others. Whether it will be a good change or not, is something only time will tell. Unfortunately unless global warming trends turnaround soon, not much can be done to reverse this situation.
