I'm part of the Roots & Shoots program founded by Dr. Jane Goodall. The program is intended to make and promote positive changes in the world. As Dr. Goodall says, "What you do makes a difference, and you have to decide what kind of difference you want to make."

    In Bulgaria, where I live, homeless dogs are everywhere. Many people here turn a blind eye to them. But I cannot ignore the life of a street dog whenever I see one wandering in the street, looking for something to eat. That's why I'm no longer a food waster. When I see wasted food, I always think of a hungry dog climbing to garbage bins, searching for food that people have thrown there. When eating in a restaurant, I'm not afraid to take leftover food to feed stray cats or dogs.

    A week ago, I saw a homeless dog around the garbage bins. Immediately I knelt down, spoke to her softly and ran my hands over her. I could see that she had had puppies. I couldn't imagine how she could have been able to care for them. Hours earlier, I'd bagged up a plate of leftover fish. As I unwrapped it, she wagged her tail and sniffed at it. She ate all the fish in no time.

    It's sad, isn't it? I can't understand why many of us waste so much and think little of it. These homeless animals have taught me that food is precious. Even when I don't have leftovers with me, I'll take the time to get something from the grocery store to feed them.

I know my power is small, so I hope that next time you see wasted food, do turn it into worthy food. You have the power to save a life!

    Technology offers conveniences such as opening the garage door from your car or changing the television station without touching the TV.

    Now one American company is offering its employees a new convenience: a microchip implanted in their hands. Employees who have these chips can do all kinds of things just by waving their hands.Three Square Market is offering to implant microchips in all of their employees for free.Each chip costs $300 and Three Square Market will pay for the chip.Employees can volunteer to have the chips implanted in their hands.About 50 out of 80 employees have chosen to do so.The president of the company,his wife and their children are also getting chips implanted in their hands.

    The chip is about the size of a grain of rice.Implanting the chip only takes about a second and is said to hurt only very briefly.The chips go under the skin between the thumb and forefinger.With a chip in the hand,a person can enter the office building,buy food,sign into computers and more,simply by waving that hand near a scanner.The chips will he also used to identify employees.Employees who want convenience,but do not want to have a microchip implanted under their skin,can wear a wristband（腕带）or a ring with a chip instead.They can perform the same tasks with a wave of their hands as if they had an implanted chip.

    Three Square Market is the first company in the United States to offer to implant chips in its employees.Epicenter,a company in Sweden,has been implanting chips in its employees for a while.

    Three Square Market says the chip cannot track the employees.The company says scanners can read the chips only when they are within a few inches of them.“The chips protect against identity theft,similar to credit cards.”The U.S. Food and Drug Administration approved the chips back in 2004,so they should be safe for humans,according to the company.

    In the future,people with the chips may be able to do more with them,even outside the office.Todd Westby is Chief Executive Officer of Three Square Market.He says,“Eventually,this technology will become standardized allowing you to use this as your passport,public transit,all purchasing opportunities,etc.”

    Two friends have an argument that bleaks up their friendship forever, even though neither one can remember how the whole thing got started. Such sad events happen over and over in high schools across the country. In fact, according to an official report on youth violence, "In our country today, the greatest threat to the lives of children and adolescents is not disease or starvation or abandonment, but the terrible reality of violence". Given that this is the case, why aren't students taught to manage conflict the way they are taught to solve math problems, drive cars, or stay physically fit?

    First of all, students need to realize that conflict is unavoidable. A report on violence among middle school and high school students indicates that most violent incidents between students begin with a relatively minor insult (侮辱). For example, a fight could start over the fact that one student eats a peanut butter sandwich each lunchtime. Laughter over the sandwich can lead to insults, which in turn can lead to violence. The problem isn't in the sandwich, but in the way students deal with the conflict.

Once students recognize that conflict is unavoidable, they can practice the golden rule of conflict resolution—stay calm. Once the student feels calmer, he or she should choose words that will calm the other person down as well. Rude words, name-calling, and accusation only add fuel to the emotional fire. On the other hand, soft words spoken at a normal sound level can put out the fire before it explodes out of control.

    After both sides have calmed down, they can use another key strategy for conflict resolution: listening. Listening allows the two sides to understand each other. One person should describe his or her side, and the other person should listen without interrupting. Afterward, the listener can ask non-threatening questions to clarify the speaker's position. Then the two people should change roles.

    Finally, students need consider what they are hearing. This doesn't mean trying to figure out what's wrong with the other person. It means understanding what the real issue is and what both sides are trying to accomplish. For example, a shouting match over a peanut butter sandwich might happen because one person thinks the other person is unwilling to try new things. Students need to ask themselves questions such as these: How did this start? What do I really want? What am I afraid off? As the issue becomes clearer, the conflict often simply becomes smaller. Even if it doesn't, careful thought helps both sides figure out a mutual solution.

    There will always be conflict in schools, but that doesn't mean there needs to be violence. After students in Atlanta started a conflict resolution program, according to Educators for Social Responsibility, "64 percent of the teachers reported less physical violence in the classroom; 75 percent of the teachers reported an increase in student cooperation; and 92 percent of the students felt better about themselves". Learning to resolve conflicts can help students deal with friends, teachers, parents, bosses, and coworkers. In that way, conflict resolution is a basic life skill that should be taught in schools across the country.

    Castle Dale is a small town in central Utah. My grandpa's farm is a few miles to the north. I grew up there. Milking a cow, feeding the chickens and cutting firewood were daily routines. Grandpa had me carrying a broom to do snow cleaning when it was actually taller than I was. This was the work kids like me learned to do at a young age.

    I was tall, very tall at a really young age. My unusual height caused people to look, ask questions, laugh, tease, and sometimes even challenge me to fight. I was teased cruelly as a kid. It wasn't fair, I knew, but that was just the way it was. Luckily, I was taught at a very young age a very important lesson. I am different and that's Okay—I'm unique and I matter. No one could ever take that away from me. I knew this then, and I know this now. That alone helped me through the frustrations and heartaches of normal life.

    When I was in junior high school, I realized something else that helped me cope. Most teasing came from one of two places—people who were either jealous or ignorant (愚昧). I couldn't change the way they were, but I could change the way I felt. I was not going to feel bad because of their ignorance or jealousy. It wasn't worth it. Realizing this didn't stop them, or change the fact that these comments hurt. It did, however, give me a way to understand these people and deal with their treatment in a way that was okay for me.

    These things still happen today. It will probably happen the rest of my life. I will always be 7 feet, 6 inches (2.29 meters) tall. I wouldn't change that for anything. People will always look because it is not every day that you see someone that tall. I learned that at a young age and I now try to teach my own children that they are unique and they matter. That is the message I give to you. Regardless of your race, religion, background, or circumstances ... Being different is okay.

    Charity Cycling UK has recently launched a campaign to raise awareness of dooring after discovering that many people don't know what it is and those that do seem to think it's a joke. Dooring happens when a driver or passenger opens the door into another road user - typically a cyclist - without looking for other road users.

    Cycling UK's chief executive Paul Tuohy told Gloucestershire Live, "Some people seem to see car dooring as a bit of a joke, but it's not and can have serious consequences. Cycling UK wants to see great awareness made about the dangers of opening your car door, and people to be encouraged to look before they open."

    The charity says 2,009 of the 3,000 injuries were sustained(遭受) by cyclists, resulting in five deaths but says this might not be the full extent of the dangers.

    Cycling UK says not all car dooring incidents will be attended by police, so the charity has written to transport minister Jesse Norman calling for a public awareness campaign urging all drivers to look before opening vehicle doors. One of the ways that the charity suggests could prevent injuries through dooring is the "Dutch Reach", where people leaving a vehicle reach over and use the non-door side hand to open the door.

    Cycling UK also suggests serious laws and advice on safer road positioning for people who cycle.

    Mr Tuohy said, "In the Netherlands they are known for practising a method, known sometimes as the 'Dutch Reach', which we think could be successfully encouraged in the UK."

    "Cycling UK has written to the Department for Transport asking them to look into this, and stress the dangers of 'car dooring' through a public awareness THINK style campaign."

    If you're really concerned about opening a door into the path of a cyclist coming behind you, consider using what's known as the "Dutch Reach" to open the door. That will naturally turn you in your seat and give you a much better view of what's coming up alongside the car.
