Bottled water has become the choice for people who are healthy and thirsty. Bottled water is all over the world. But some say the planet's health, and people's health may be suffering from it.

    The idea that bottled water is safer for humans may not be true. The Natural Resources Defense Council of America said, “There is no promise that because water comes out of a bottle, it is cleaner or safer than water from the tap.” Another New York City-based action group added that some bottled water is “really just tap water in a bottle—sometimes more clean, sometimes not.”

    It is not proven that bottled water is better than tap water. Nick Reeves from the Chartered Institution of Water and Environmental Management said, “The high mineral content(含量) of some bottled water makes them not good for feeding babies and young children.” Also, most bottled water doesn't have fluoride(氟化物), which can make teeth stronger. Kids are drinking more bottled water and less fluoridated tap water, and some say that's behind the recent rise in bad teeth.

    Storing is another problem. Placed near heat, the plastic bottles can produce bad chemicals(化学物质) into the water.

    According to the Environmental Protection Agency, some 2.7 million tons of plastic are used worldwide to bottle water each year. The plastic can take between 400 and 1,000 years to break down.

    In terms of energy use, plastic bottles are also not cheap. One report said that if water and soft drink bottlers had used 10 percent recycled materials in their plastic bottles, they would have saved about 72 million gallons of gas.

    So, if you are worried about the effect of bottled water on the Earth, you can take the following steps.

●Drink from your tap. Unless your government warns against this, it should be fine.

●Get a container(容器). Carry your tap water in a steel or a lined drinking container, and clean it between uses.

●Keep it cool. Don't drink from a bottle that has been sitting in the sun, don't store it near chemicals, and don't reuse plastic bottles.

●Choose glass containers over plastic if possible. When finished, recycle!

    Well, parents, surprise! Lots of us are using Twitter and Facebook to thumb rides, and not just to school. It's awkward to be refused when you call a friend and ask for a ride. But with Twitter, you just look for other people heading the same way.

    It may sound risky, so many teens stay within their own social circles to find rides, and don't branch out beyond friends when asking on Twitter just like me, but to some young people, especially those taking longer trips, stranger danger is less of a concern.

    “I think the digital connection of young people is really important, because younger generations grew up sharing things on line, sharing files, photos, music, etc, so they've been very used to sharing,” said Juliet Schor, a sociology professor at Boston College.

    The sharing economy got big during the recession (经济衰退), allowing people to access more goods, services using technology and even to share costs. And that technology, for me, is what the car was for my mom, a gateway to more freedom, like what my friend Earl says, “The symbol of freedom isn't the car any more because there's technology out there connecting you to a car.”

    According to the researchers at the University of Michigan, 30 years ago, eight in ten American 18-year-olds had a driver's license compared to six in ten today. So it's not that surprising that on my 16th birthday I wasn't rushing to get a license but an iPhone.

“Driving, for young people, does mean they have to disconnect from their technology, and that's a negative. So if they could sit in the passage side and still be connected, that's going to be a plus.” Schor continued.

    To me, another plus is that ridesharing represents something, something much bigger than trying to save money. I see it as evidence that people still depend on each other. My generation shares their cars and apartments the way neighbors used to share cups of sugar. For the system to work, some of us still need our own cars. But until I get my own version of the silver Super Beetle, you can find me on Twitter.

    This year's flu season is pretty scary. To try to minimize the effects, public officials are still urging anyone who hasn't yet gotten their flu shot to get one as soon as possible. However, even if every single person got a shot in the arm, the vaccine(疫苗)—with its excellent 36 percent effectiveness—would not prevent everyone from getting infected with the annoying virus. Knowledge is power, so here's what goes on in your body when you come down with the flu.

    The influenza virus primarily attacks your nose, throat, and the tubes that lead to your lungs. But the flu is so much more than that. Your muscles ache, your head hurts, and your appetite goes down, among other things. To our surprise, almost all of these symptoms have less to do with the virus itself than with your immune(免疫的)response to them. Unfortunately, the very defense you have in place to get rid of the flu is the reason you feel so painful when you recover.

    The virus usually enters through your mouth, typically by way of your hands But it takes a few days for symptoms to set in. While this process might cause some harm to your nose and throat, it's nothing major, and nothing like the symptoms that typically accompany a bad or even mild case of the flu.

    The real fun starts when your immune system begins to fight. Your immune system comes in two parts: the innate system and the adaptive. The innate immune system is essentially an all-purpose tool. As soon as your body senses the presence of any injury or invader (入侵者), the innate immune system launches into action by producing tiny proteins called cytokines and chemokines. The cytokines reproduce almost immediately and start to attack the virus. This increase in immune cells creates an serious inflammation(炎症) throughout the body. But the worst is still to come. Meanwhile, the chemokines work with the adaptive immune system to help create T cells. These cells are a special type of white blood cell that works in a much more specific way: They find the influenza virus, identify what's special about it, and create something unique on their surface that finds and destroys similar invaders.

    If cars had wings, they could fly and that just might happen, beginning in 2012.The company Terrafugia, based in Woburn, Massachusetts, says it plans to deliver its car­plane, the Transition, to customers by the end of 2012.

    "It's the next 'wow' vehicle, "said Terrafugia vice president Richard Gersh. "Anybody can buy a Ferrari, but as we say, Ferraris don't fly."

    The car plane has wings that unfold for flying—a process the company says takes one minute—and fold back up for driving. A runway is still required to take off and land.

    The Transition is being marketed more as a plane that drives than a car that flies, although it is both. The company has been working with FAA to meet aircraft regulations, and with the National Highway Traffic Safety Administration to meet vehicle safety regulations.

    The company is aiming to sell the Transition to private pilots as a more convenient and cheaper way to fly. They say it saves you the trouble of trying to find another mode of transportation to get to and from airports: You drive the car to the airport and then you're good to go. When you land, you fold up the wings and hit the road. There are no expensive parking fees because you don't have to store it at an airport—you park it in the garage at home.

    The car­plane is designed to fly primarily under 10,000 feet. It has a maximum takeoff weight of 1,430 pounds, including fuel and passengers. Terrafugia says the Transition reduces the potential for an accident by allowing pilots to drive under bad weather instead of flying into marginal(临界)conditions.

    The Transition's price tag: $194,000. But there may be additional charges for options like a radio, transponder or GPS. Another option is a full­plane parachute.

    "If you get into a very awful situation, it is the necessary safety option," Gersh said. So far, the company has more than 70 orders with deposits. "We're working very closely with them, but there are still some remaining steps," Brown said.

Growing up, we are constantly reminded that young people are heavily affected by technology. We are the "antisocial club", those who prefer to text our friends in the same room rather than make eye contact with them. And even though never-ending studies reveal to us the extent of our social media addiction, we should at least consider that it's not only our young people's problem any more.

There's the rise of the Instagram mums, who like to post an abundance of cute baby pictures, share their mom feelings along the way and show their wonderful lifestyles. They are the so-called "Facebook mum generation", a growing group of parents that like to overshare.

While all of this might be fine, and even a little humorous, new research suggests that parents' technology addiction is negatively affecting their children's behavior. According to the study, 40% of mothers and 32% of fathers have admitted having some sort of phone addiction. This has led to a significant fall in verbal interactions within families and even a decline in mothers' encouraging their children.

There is no denying that I get annoyed when receiving the words "I'll be with you soon" from a parent, when all I want to do is ask one question. But, at the same time, every day leaving the room to wait until my father is finished with his "serious business" (Farmville), has now become the norm. Whether you want to escape your disturbing children for a bit, or want to stay up late flicking through Twitter, know that wanting to do all of these is normal. We, your children, know how addictive it can be and how difficult it is to switch off. But before telling us to put our phones away at the table or even worse, listing statistics of how damaging social media can be for us, maybe lead by example, considering how much time you spend on the phone and how this is impacting your children and your relationship with us. Maybe in this way we can work on our addiction together.
