Current Events 8 Death Of the Polar Bear
Polar Bears Soon to Extinct
Have you wondered about this question“ Will polar bears survive in a warmer world?“ well the answer is probably no. Imagine your grandchildren not knowing what a polar bear or not seeing one, that would be very sad. Now I will present the facts why this is true.
As polar bears lose habitat due to global warming, these biologists say, they will be forced southward in search of alternative sources of food, where they will increasingly come into competition with grizzly bears.
To test how this competition might end, the UCLA biologists constructed three-dimensional computer models of the skulls of polar bears and grizzly bears subspecies of brown bears and simulated the process of biting. The models enabled them to compare the two species in terms of how hard they can bite and how strong their skulls are.
The implication is that polar bears are likely to lose out in competition for food to the Grizzle bears, therefore they would die out. This will shake the whole food chain, and the animals habitats.
Grizzlies as warmer temperatures bring them into the same environments, because grizzlies' stronger skulls are better suited to a plant-rich diet, said Slater and Blaire Van Valkenburgh, UCLA professor of ecology and evolutionary biology and senior author of the research.
In conclusion as you see there are many possibilities for these animals (polar bears) to die out (go to Extinction). I believe that this has a very negative effect to the environment, if these animals do die out the food chain could corrupt or be severely shaken. I believe that extinction is a huge issue in the modern world, not many people are trying to stop it, although many laws have been passed about pollution, and I believe that if there was any chance for us to abide these laws there could be a possibility of stopping this major pollution issue (this would also help us for other problems that have something to do with pollution.)

Technology Fights Hospital Infections
Hey! Wouldnt it be sad if your grandmother is in the hospital and suddenley gets a Hospital Infection, that the doctors cant cure and she might die! Well you should britten up your mood because i have something that can cure your granny, it was made a cuple of thousand years ago, its called technology. But its actually HINS light (wich is Technology). In this Report I will explore the ways that this type of technology can cure patients.
The technology decontaminates the air and exposed surfaces by bathing them into visible-light, known as HINS-light. The clinic at Glasgow Royal Infirmary has proven that Environmental Decontamination System provides significantly greater reductions of bacterial pathogens in the hospital environment than can be achieved by cleaning and disinfection alone, providing a huge step forward in hospitals' ability to prevent the spread of infection. Technology was discovered and developed by a multidisciplinary team of experts, Professor Scott Macgregor (Electrical Engineer), Professor John Anderson and Dr Michelle Maclean (Microbiologists) and Professor Gerry Woolsey (Optical Physicist.) Professor Anderson stated: “The technology kills pathogens but is harmless to patients and staff, which means for the first time; hospitals can continuously disinfect wards and isolation rooms.” This means that it can help the human kind with no problems.
In conclusion I believe that this is something that can really help us because there are no Cons to this “invention” there are only Pros which will really help humans but mostly patients, and even staff (staff of the hospital.)

This Video that we watched in class was called "Human Footprints" it was Posted by National Geographic.
The video spoke a lot about sustainability. What is sustainability?
Sustainability is the property of being sustainable so it basically means how it is possibly to stand against to sustain in varuis situations. |

Current Events 6 (Energy Harvesting)
Eco Harvesting
Have you ever though “oh it would be sooo...... cool if a Nanogenerator would be able to power electrical devices so it would develop our environment” of course you have! And I am going to make your dreams come true, because they are true, I will explain to you why they are true.
The laboratory of Zhong Lin Wang at Georgia Tech, discovered that the blinking number on a small LCD signals the success of a five-year effort to power conventional electronic devices with nanoscale generators that harvest mechanical energy from the environment using an array of tiny nanowires. The mechanical energy is able to fit in between your finger (it is very small). These sources of energy could be used to power nanoscale and microscale devices and even to recharge pacemakers or iPods. "By simplifying our design, making it more robust and integrating the contributions from many more nanowires, we have successfully boosted the output of our nanogenerator enough to drive devices such as commercial liquid-crystal displays, light-emitting diodes and laser diodes," stated Wang. Recent improvements in the nanogenerators, including a simpler fabrication technique, were reported online last week in the journal Nano Letters.
Conclusion
In conclusion I believe that this could really improve our environment because of all the energy. This device can power every day materials without hurting the Economy which in my opinion is very helpful, this product would also be cheap (affordable) which is great again for the Economy.

Current event 5
Two Tons of Carbon Dioxide Through Eating
FOOD
Have you ever thought about how much CO2 you are breathing wild eating in a year? Of course you have not that why I’m bringing it up, over 2 tons of Carbon Dioxide is being inhaled!
A group of Spanish Scientists have discovered that human excrements play in the life cycle of food. It is the first time that a scientific study of this type incorporates the role played by human excrements. “Food in Spain produces emissions of around two tons of carbon dioxide per person and per year (more than 20% of the total emission per person and per year) and consumes 20 gigajoules of primary energy," states Iván Muñoz, the main author of the study and researcher at the UAL. According to the study, producing food from animals, such as meat and dairy products, causes the greatest impact. Human excretion contributes dramatically to water polluting through providing organic matter and nutrients, such as nitrogen and phosphorus, which fosters the growth of algae, a decrease in the level of oxygen dissolved in the water, bad smells and other problems associated to eutrophication.
In conclusion I believe that this Event is not needed because there is no way to stop humans from excreting waste, and even if there was it would be extremely unhealthy. So I believe that this event should not be valid.
