Discussions Discussion Green Efforts for the Community
Sara LUSA, Oct. 9, 2013

Years ago, when the phrase ‘global warming’ began gaining popularity, researchers and engineers, along with U.S. Senator Mike Crapo, started looking at the idea of solar roadways. These roadways would replace the concrete and asphalt roads that communities have today. The roads would be made up of glass solar panels that would absorb solar energy, providing power for surrounding communities. These solar panels could make up highways, toll roads, freeways, neighborhoods, and much more.

    That would be a great way to take advantage of the light energy that hits our planet each day. I read an interesting fact today that stated that solar panels would be able to meet human's energy demands if they covered 1% of Earths surface. Putting solar panels in our roads would really help make renewable energy the one and only energy source.

    That would be great! It's the first time I've heard of this, but thinking about it, it also seems like the Maglev Trains. It carries more people and is more efficient with speed and use solar energy. But I these trains are only found in China, South Korea, and Japan.

Discussions Discussion Wants or needs?
Brittany H-usa, Oct. 4, 2013

I feel that our world is based off technology, so I feel that though we need it, the great features that come with technology makes it a want. I upgrade my cell phone every two and a half yeas but I use my cell phone as my mp3 player. I have a Samsung galaxy s4 brand new phone i didn’t really need the Samsung galaxy 4 but i wanted it because of all the cool features. More powerful our technology the more energy we use to run and to use these high powered electronics. I do not consider myself a addict when it come to technology its just everyday in some way i am forced to use it.

    Hi, my name is Jade and I completely 100% agree with you. People rely so much on technology, whether it's their iPhone or their iPods or their laptops, you see them being used everywhere! People even take pictures of notes on their phones, and add alarms to remind themselves of things. It's wild how much we need technology, and I feel as if it runs our lives. Usually, one would change their phone every two years, but the ATT phone company has started a new plan where you can change it every six months.

Discussions Discussion Sustainable city
eric shong, Nov. 6, 2012

Greetings, everyone. I am Eric Shong, a 14-year old student from Dominican International School of Taiwan. I have noticed the sudden and huge rise of carbon emissions in the past 60 years, form 1950 to 2012. The global emission percentage has rises from 1400 million tons to a amazing 6500 million tons. Mainly because the increasing level of technology, such as the greatest contributor to carbon emissions - cars. The problem is, we simply can’t do anything about that. People travel, and for this reason they need cars. You could say that they could use public transportation, but public transportation may not always go to specific locations, and it will be tougher to travel around with a bus with luggages. Even though, we are left with another opportunity, reduce electric use. In most countries, electricity is produced by thermal power stations, which produce a significant amount of carbon dioxide. By reducing use of electricity, the power stations will need to produce less and therefore also produce less carbon dioxide.

Discussions Discussion Food and Gender
Emily Nelsen, Nov. 8, 2011

Good background article about food and gender and their interactions. Its interesting that this stuff involves everyday life but we take it for granted. For me its interesting food for thought- pun intended!

Across many cultures and epochs, people have constituted, expressed, and bridged gender differences through foodways—the beliefs and behaviors surrounding the production, distribution, and consumption of food. Through the division of labor, alimentary exchanges, access to food, and the meanings surrounding eating, men and women have enacted their identity, roles, and power.
