Input: Consider Input: Article: While there are some unpleasant people in the world, let's not forget that most people are friendly! If you find someone who likes the same restaurants as you or who is also crazy about "Harry Potter", then feel free to talk the night away! Just keep the conversation light and about your common interests. If a topic is brought up that doesn't sit well with you, keep in mind that you are always in control. Ignore your manners at this time! Do stay open-minded. Sometimes chatting with strangers can turn into a close bond--or just another person you can turn to for a laugh. But when typing away in your computer, it's easy to get carried away and to want to tell your new friend all about yourself. Keep the personal details as secret, and instead talk about fun hobbies or the latest episode of "The Good Wife". If Stranger Sally is asking what you look like, time to put up the red flag. It is never necessary for someone to know what you look like. Always listen to your gut .If something inside you is telling you something isn't right, it probably isn't. Pay attention to how your body responds to certain people online. Remember, you never really know who you are talking to just by looking at a computer screen name, so downloading anything is an no. See? Talking to strangers online doesn't always have to be a nightmare .By following these do's and don'ts, chatting with someone you don't know can be a cool experience,and can make sure that you stay safe in the world of the Internet.

Input: Consider Input: Article: We produce 500 billion of plastic bags in a year worldwide and they are thrown away polluting oceans, killing wildlife and getting dumped in landfills where they take up to 1000 years to decompose. Researchers have been unsuccessfully looking for a solution. The 16-year old Canadian high school student, Daniel Burd, from Waterloo Collegiate Institute, has discovered a way to make plastic bags degrade in as few as 3 months, a finding that won him first prize at the Canada-Wide Science Fair, a $10 000 prize, a $20 000 scholarship, and a chance to revolutionize a major environmental issue. Burd's strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms . If those microorganisms could be identified, we could put them to work eating the plastic much faster than under normal conditions. With this goal in mind, he ground plastic bags into a powder and concocted a solution of household chemicals, yeast and tap water to encourage microbes growth. Then he added the plastic powder and let the microbes work their magic for 3 months. Finally, he tested the resulting bacterial culture on plastic bags, exposing one plastic sample to dead bacteria as a control. Sure enough, the plastic exposed to the live bacteria was 17% lighter than the control after six weeks. The inputs are cheap: maintaining the required temperature takes little energy because microbes produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide. "Almost every week I have to do chores and when I open the closet door, I have piles of plastic bags falling on top of me. One day, I got tired of it and I wanted to know what other people are doing with these plastic bags. The answer: not much. So I decided to do something myself." said Daniel Burd.
