Great white shark killed California surfer

http://www.cnn.com/2012/10/24/us/california-shark-attack-death/index.html?hpt=hp_c2


Since we have been talking about sharks, I found that this is an interesting article. A great white shark that killed the suffer was said to be about 15 to 16 feet long. The shark attacked a 39 year old man and bit him n his torso. He was attacked off the coast of Vandenberg Air Force Base. The man was pulled out of the water and had CPR performed, but to no avail. The man was pronounced dead at the time the paramedics arrived at the scene. This is the second attack in the same area within the past two years, and both people died.

Elevated carbon dioxide may impair reasoning

Elevated carbon dioxide may impair reasoning 

This article talked about how CO2 levels effected how people would think. The normal outdoor CO2 level is 400 ppm. The indoor amount can range anywhere from 600 ppm which is considered a good amount, or as high as 2,500 ppm. Researchers set up a test which got college students to gather n a room together for 2.5 hour intervals. The researchers then changed the amount of CO2 that was vented in and out of the room. While the students were in the room they used computers and had to role play on them. The students were put through a series of tests on the computers and had to do an organization game and try to manage it as it went through and series of problems. The study wanted to see what would happen with different levels of CO2. The study revealed that ventilation has to be increased in classrooms for all students to be able to think and react better.

Bird Extinctions on the Rise

I found this interesting because this study only goes back 500 years. Human population is on a rise, just like it has been for thousands of years. Before humans were around this land was occupied by different animals like birds, mammals, rodents, and water life. As the human population increases the natural resources and forests decrease. Over the past 500 years, 279 different species of birds have gone extinct. That equals to one bird species going extinct ever 1.8 years. As humans keeping spreading throughout the world, and its islands, birds habitats are being taken over and are forced to move out. Most of the birds ended up staving to death because their food became the food of the humans, and because it was also being destroyed.

The $1 billion mission to reach the Earth's mantle

My article was pretty interesting, and government is doing something that has never happened before.   The government is going to create a plan to drill 3.7 miles beneath the sea floor into the earths mantle. This will allow scientist to test different samples and could show a lot about evolution. No one has ever been this deep inside of the earth, and once the government drills into the mantel, they can test samples and learn about pre existing life. Groups of international scientists have been getting together and they first have to come up with a way to drill through 6.2 miles of solid rock before they can even begin drill to the mantle. This whole experiment will take place in the middle of the ocean.  The bedrock is the thinnest in the oceans, so they want to drill there.
