50 ways to go green

You can be good to the earth--without giving up things you love. Plus, what those "eco" labels really mean. 
At the supermarket

Be picky about produce

Download the "Shoppers' Guide to Pesticides in Produce" at ewg.org. The wallet-size list sorts out the fruits and veggies that tend to be higher in pesticides (like apples and spinach) from produce with a lower count (like bananas and peas).
Choose "certified" coffee

Yuban coffee is Rainforest Alliance Certified (that means it's grown in a way that preserves the ecosystem). A Fair Trade Certified brand is Green Mountain Coffee Roasters. (Both brands are available at many markets.) For more on these certification labels, see the chart.
Support local farms

At eatwellguide.org, you can plug in your zip code and find suppliers of organic and sustainably produced meat, poultry, eggs, and more. If you buy locally, you won't have to rely on farms that ship food nationwide, which helps to decrease our dependence on oil and to cut back on gas emissions.

Tote your own grocery bag

Paper or plastic? Neither! If you're shopping for a small load, bring along a cute sack like the polka-dot tote, above, from Cath Kidston (cathkidston.com). Another practical option: the ACME Workhorse Style 1500 (reusablebags.com), which crunches into a tiny pouch that fits in your purse.
Pay attention to packaging

Every American produces about four and a half pounds of garbage a day. So before you buy something, eyeball the amount of cardboard, plastic, and/or other materials used for the box or wrapping. Wal-Mart is one big retailer that is waking up to the problem: The chain is replacing petroleum-based plastic containers with corn-based packaging for precut fruit, herbs, strawberries, and Brussels sprouts.

Around the house
Save money in the bathroom Buy water-efficient showerheads. With low-flow models, a family of four can cut water usage by as much as 280 gallons a month-and yet not feel much difference in water pressure. Two we like: Kohler's Master Shower Eco (kohler.com) and Niagara Conservation's Earth Massage (niagaraconservation.com).
Bring home superhero plants
Certain greens can help remove indoor air pollutants like formaldehyde and benzene. Don't have the gardening gene? Golden pothos, English ivy, and peace lilies are all easy-to-grow toxin fighters.
Recycle rechargeables
Cell phones, digital cameras, and camcorders have made these batteries more popular than ever, but in certain states-Florida, Iowa, Maine, Maryland, Minnesota, New Jersey, and Vermont-it's illegal to throw them away. Wherever you live, you can find a nearby store that will recycle them for you; just go to rbrc.org and type in your zip code.
Adjust fridge and freezer temps
Refrigerators eat up the most electricity in the household. Maximize efficiency by keeping the fridge at 37°F. and the freezer at 0°F.
Lighten up with energy savings
Consider using compact fluorescent lightbulbs (CFLs). They cost a bit more than regular bulbs, but you'll lower your electric bill and pay less in the long run-CFLs last up to ten times longer than traditional ones. (Worried that fluorescents will fill your house with a greenish glow? That's no longer a problem. When we compared a regular bulb with a GE Energy Star Qualified CFL, testers couldn't tell the difference.) You can buy CFLs at most hardware and home stores. To save more on lighting, install dimmer switches and use timers, indoors and out.
Recycle smart
From furniture to electronics, one person's trash is another's treasure-so when you want to dispose of an old item, don't make the dump your first stop. Two sites with alternatives: freecycle.org and earth911.org. The Freecycle Network describes itself as "a place to give or receive what you have and don't need or what you need and don't have-[to keep] stuff out of landfills." The Earth 911 Web site offers community-specific resources, with a focus on recycling. Check out the home page to find out where you can recycle your computer, your cell phone-even used motor oil.

Entertaining
Protect the earth while you picnic
At your next outdoor party, ask people to write their names on disposable cups so they'll use only one (to make it easy, put out markers). If you use disposable dinnerware, buy the kind that won't clog landfills or kill trees. To try: EarthShell plates and bowls (www.earthshell.com). They're made from corn, potatoes, and limestone-and cost less than 6 cents per plate.

Remodeling
Take paint precautions
Most paint emits VOCs (volatile organic compounds), the same kind of chemicals found in gasoline and nail polish. But manufacturers like Sherwin-Williams have developed water-based products that perform well but give off virtually no VOCs. Krylon's H20 paint is the first low-VOC latex spray paint that can be cleaned up with soap and water. Made from 99 percent food-grade ingredients, Anna Sova's Healthy Wall Finish (annasova.com) leaves your rooms smelling vaguely like vanilla. To be at least minimally organic, use a water-based latex paint, not an oil-based alkyd paint-and remember, exterior paints should never be used indoors.
Raise the roof with recycled materials
If your old shingles need replacing, consider a Classic Metal Roofing System (classicroof.com). It's made from recycled aluminum cans but resembles traditional shakes or tiles. Thanks to the Energy Policy Act of 2005, installing this type of material can qualify you for a $500 tax credit.
Choose energy-efficient appliances
Look for the Energy Star label, awarded to fridges, washers, and other products that exceed government efficiency standards by using less water or electricity. For Energy Star appliances that have been tested by GHI, visit goodhousekeeping.com.

Personal style
Dress in eco-chic clothing
Lara Miller's Melissa tunic is 100 percent bamboo, yet it's as soft as silk. (For stores, go to laramiller.net.) Linda Loudermilk, an eco-couture designer, uses fabric made from sasawashi (a Japanese leaf), along with bamboo, soya, and other exotic self-sustaining plants(lindaloudermilk.com).
Opt for new undies
Wearing 100 percent organic-cotton panties reduces your exposure to chemical pesticides in a sensitive area. Try Blue Canoe brand (goodhumans.com).
Make up with Mother Nature
Aveda's All-Sensitive Body Formula moisturizing body oil uses organic jojoba. What's more, most of Aveda's packaging is made from recycled material. A makeup line that's entirely organic: Nvey Eco (econveybeauty.com). We particularly like their eyeshadows.
Get sporty, eco-style
Patagonia's PCR fleece vest ($70) is made from recycled soda bottles.
Be clean (and green)
Pangea Organics soaps, which are made with organic and often Fair Trade Certified ingredients, are scented with oils like lavender and lemongrass. They come in a biodegradable carton that will start disintegrating within 48 hours if you plant it in your garden. Available at Whole Foods Markets.

Cooking and eating 
Become a flexitarian
Swap out one meat dish a week for a veggie plate. Why? Because raising produce is "cheaper," in terms of energy, than raising animals. Log on to vegweb.com to find tasty, meatless recipes (our favorite: the lentil burgers).
Grill corn in its husk
Instead of stripping off the green leaves, soak the ear whole, then place it right on the barbecue-no aluminum foil required.
Go for the gold- coffee filters, that is
Spare trees by replacing paper filters in your coffeemaker with reusables (usually gold colored).
Get the organic habit
Switch to organic for at least one product that you buy every week.
Put it in park
Avoid drive-through windows, especially if there are long lines.
Compost
Instead of trashing food scraps, toss them into Gardener's Supply Company Kitchen Compost Crock, a ceramic countertop composter that's perfect for first-timers (gardeners.com).
Break out the bamboo
This plant is a far more sustainable natural resource than wood because it grows very quickly. Try the stylish bamboo bowls and cutting boards from TimberGrass (lamsonsharp.com).
Home office
Buy a laptop
It uses considerably less power than a desktop computer.
Get off junk mail lists
Register with the Direct Marketing Association's Mail Preference Service (dmaconsumers.org) and you'll see a significant reduction in mail after three months.
Double up on printing
Configure your printer so that it prints on both sides of the page. You know those extra pages you get when printing out one simple e-mail? Turn them over and put them back in the printer for reuse.
Invest the green way
Environmentally conscious mutual funds are increasingly available through 401(k) plans, especially if employees express interest. To learn more, log on to socialinvest.org; then talk to your benefits administrator.

For kids
Buy organic for baby
Hanna Andersson makes her children's clothing-including the romper at left-with 100 percent organic cotton grown without harmful chemicals (hannaandersson.com). This garment is also certified to meet the Oeko-Tex Standard 100 requirements, meaning every fabric, button, thread, and zipper is tested for over 100 potentially harmful substances. Another source for organic-cotton baby clothes is Wal-Mart's new George Baby line for sizes up to nine months.
Teach kids to be green
Give your little ones responsibility for your family's recycling and match whatever they make in deposits at the store. They'll learn about money and recycling at the same time.
In your yard
Mow-ercise!
Today's non-gasoline-powered reel lawn mowers are easier to push than the old models. Their eco-benefit: zero emissions (plus, you're getting great exercise). If you prefer a power mower, consider a quiet, battery-operated model from Black & Decker.
Warm up to solar energy
You may not be ready for a totally sun-powered home, but you can get a taste of the technology by using solar-powered lighting in your yard or on your patio. We like Malibu's Solar Floodlight (intermatic.com).
Go native
Plant flowers and shrubs that are well suited to your climate (the staff at your local nursery can help). The benefit: You'll use less fertilizer and pesticides.
Five eco labels you can really trust

10 tips to get good grades

1. Attend All Your Classes
Now, you might think this was an obvious one. But I speak from experience when I say that many students skip classes for one reason or another. But if you want good grades, there are several reasons why you should attend all your classes:

• Absorb classroom material. Even if the professor follows the textbook pretty closely, sitting in the classroom and listening to the lectures/discussions will help you absorb the materials.
• Make presence known/participate. One of the benefits of going to college should be that you form a mentoring relationship with some of your professors, and that's not going to happen if you don't attend the classes. And often faculty have participation points (or bonus points), so beyond just attending, make an effort to be involved in the class discussions.
• Earn attendance points. Many professors have attendance policies, so you can have a direct impact on your grade simply by attending.

Don't forget to sit close to the front -- historically, those who do are usually the best students.
2. Master Your Professors
Every professor has a different personality and system for running his/her classes, so it makes sense as early in the semester as possible to learn what the professor wants. Here are some ways to master your professors:

• Understand course expectations. Most professors give out a class syllabus during the first week of classes -- and it is your responsibility to know deadlines and all the requirements for the course.
• Understand professors on personal level. Rather than viewing the professor as some figurehead at the front of the class who decides your fate in some abstract way, get to know your professor as a person. Visit him or her during office hours, or stay after class.
• Communicate with professors when you are struggling. Especially at larger colleges and universities, the professor won't know when you are struggling, so if you are having problems with the course work or the tests, schedule an appointment to meet with the professor and get the help you need.

3. Get/Stay Organized
You may have been one of the lucky few who has never needed a planner before, but college is all about multitasking, and you can easily get overwhelmed with due dates, team meetings, and other demands on your time. Here are some tips for getting organized:

• Use a planner or other organization system. I've had my day-planner for years and cannot go anywhere without it. Others are that same way with their personal digital assistants.
• Stay current with due dates/course calendars. It's not enough to have a system -- you have to use it! So once you have some sort of system, get in the habit of using it (and it will soon become second nature).
• Keep homework, tests, and class papers in central location. Don't just throw old homework assignments or tests in the back of your car or the floor of your dorm room. You'll need these for studying for future tests, for meeting with your professor to discuss them, and for figuring your grade in the class… so, keep all your class materials in a central location.

4. Use Time Wisely
Even if you do not procrastinate and are the most organized person in the world, time can be one of your biggest enemies in college. Here are some tips for using time wisely:

• Tackle harder work first. Yes, tackle the harder stuff first so that you are sure to have enough time to complete it. You'll feel a greater sense of accomplishment completing the work in this order.
• Take breaks as reward for work. Reward yourself for completing a major task by taking a break and chatting with a friend or watching some television. Not only are the breaks good motivation to help you complete something, you'll also be more refreshed to tackle the next bit of work after a break.
• Break larger projects into smaller, easy-to-accomplish pieces. If you have a massive term paper due at the end of the semester, break up the work into smaller chunks and assign deadlines to each part.
• Do not overextend yourself; learn to say no. Besides all your academic work, you will also be asked to get involved in all sorts of clubs and organizations while in college -- and at some point, you will have to learn to say no to some requests of your time.
• Work hard to play hard. One of my favorite students used to say that she worked hard so that she would have the time to play hard -- and that's a good balance. Just make sure you do the work FIRST.

5. Become "Noteworthy"
Another reason for attending class is recording the class notes. These notes are vital clues to what the professor thinks is the most important material for you to learn, so besides taking notes, learn how to better use them to your advantage. Here are some specifics:

• Be an active listener in class. Don't read the newspaper, gossips with friends, or text your roommate during class. Instead, listen attentively and actively -- and ask for clarification when you need it.
• Take good notes in class. Whether taking notes from scratch or following a professor's outline, the key for you will be to get the most important details down so that you can refer back to them when you need them.
• Rewrite or organize notes on your computer outside of class. This suggestion may sound a little extreme, but the writing-to-learn literature shows that you can increase your understanding and retention of material by rewriting it.

6. Use the Textbook
Professors assign textbooks for a reason -- and it's not to make you broke; it's to supplement the lectures and discussions from class. Do buy all the textbooks -- and follow these tips for using it:

• Read all assigned material. Sounds obvious, right? When a professor assigns a chapter, read the whole thing (unless told otherwise), including the opening vignettes, the case studies, and tables and exhibits.
• Know what's critical. At the same time, know what parts of the text are most critical. For example, in one of my classes, the vocabulary is most critical, and the textbook emphasizes the point by having all the terms and their definitions printed in the margins of every chapter.
• Use outlining system to help comprehend material. Reading and highlighting the material in the text is just the minimum. To get the most of what you're reading, you should also take notes and outline the material.

7. Follow Good Rules of Writing
Many classes require one or more writing assignments, from short responses to term papers, and you'll do better on these assignments if you follow these rules of good writing:

• Organize your thoughts before writing. Stream of consciousness works in a diary or journal (and may have worked in high school), but it's best to map out an outline before you start the actual writing.
• Understand requirements for paper. Every professor has a specific way he or she wants a paper organized, and it's best to know them before you start to write. Be sure to understand the reference system and all the mechanics of the paper (font, margins, cover sheet, footnotes, etc.).
• Write a draft (and get feedback when possible). Especially for larger papers, you'll have a higher quality paper (and a better grade) if you can show the professor a draft early enough before the deadline to make changes.
• Rewrite, edit, rewrite, edit, rewrite. Learn that editing and rewriting are your friends. No one is a good enough writer to whip out the final draft in one sitting. The best writers go through a process.
• Proofread, proofread, proofread. Spellcheckers catch spelling errors, but not other problems, so learn the art of proofreading. Or better, have a buddy system with a friend in which you proofread each other's papers.

8. Study, Study, Study
Another obvious one here? Perhaps, but the rule is you should be spending at least three hours outside of class for every hour in it. And for some classes, you'll find you need a lot more time than that to master the material. So, here are some suggestions:

• Study early and often. Breaking your studying into shorter periods of time will make less of a chore -- and give your mind time to absorb the material before moving on.
• Develop and practice good study habits. Make it a habit and studying will become second nature to you.
• Know how you best study, learn material. Some people need complete silence to concentrate while others like a little noise. Find what works for you and stick with it.
• Study with friends to gain support, but… don't turn it into a social event. A study buddy can be a great tool, as long as you actually get some studying accomplished.
• Make sure work is done before socializing. Studying is critical to learning, which is critical to better grades -- so do the work before heading out to have fun.

9. Be a Good Test-Taker
Just about all college classes have exams, and sometimes the exams are the major portion of your final grade, so it's important to become a good test-taker. Here are some hints:

• Know what to expect on exams. Every professor has a style of test development, so obtain old copies or ask the professor directly. Know the types of questions that will be asked -- as well as the content that will be covered.
• Read questions carefully and plan answers. Take your time at the beginning of the test to read through all the instructions and make a plan of attack.
• Pace yourself so you have plenty of time to complete all parts. And know the point v alues of questions, so you can be sure to complete the most important ones first in case time does run out.
• Ask questions. If you don't understand something, or need clarification of the question, ask the professor. Don't wait to get the exam back and find you answered a question the wrong way.

10. Polish Those Verbal Communications Skills
Many classes include a presentation component, so use these tips to improve your verbal communications skills and maximize your grade:

• Practice speeches, presentations. The best speeches and presentations are the well-rehearsed ones, so complete your script or outline early enough to have time to practice the presentation (and to make sure it falls within the specified time limit).
• If using technology, always have a back-up. Technology is great, but sometimes it fails. If you have a PowerPoint presentation, make copies of it as a handout in case you need it.
• Know the presentation situation -- and plan accordingly. Every professor has a set of guidelines when grading presentations, and many classroom set-ups are different, so know the situation before going into the presentation

Are Patrick Schwarzenegger & Miley Cyrus dating ?

Hollywood’s next power couple or just a bad rumor?
Hookup Alert! Patrick Schwarzenegger is staying tight-lipped on whispers romantically-linking him to teen starlet Miley Cyurs. The 17-year-old is the eldest son of former Governator Arnold Schwarzenegger and his wife Maria Shriver. The power couple announced their separation on Tuesday after 25 years of marriage and their disapproval of their son’s new galpal may be one of the few things the pair has agreed on in months!

Rumors floating around the Streets of Celebsville suggest that things are “heating up” between the well-to-do Californians after Pat — whose celebrity crew includes Selena Gomez and teen model Kendall Jenner — gushed about having a crush on Miley in a recent interview with Details Magazine.“Miley is so over bad boys. After she heard that Patrick was interested in her, Miley jumped into action,” a gossipmonger squeals on the pages of the May 16 issue of The National Enquirer. “It’s early, but Miley is hoping to rope Patrick into a full-fledged romance. She thinks he’s way classier than her previous boyfriends and she’s betting that the connection will help improve her bad-girl image.”

So what’s in it for Patrick? After all, the yoga-lovin’ teen sports a physique that already shows similarities to his father’s in the early stages of his career as a bodybuilder. What does he see in Miley?
“Patrick is ready for his close-up and wants a gorgeous, famous actress on his arm,” the same source explained. “Miley fits the bill perfectly.”
Tattles say Miley’s parents, who only recently began to repair their own broken marriage, are ecstatic that she’s finally taken up with a clean-cut kid after her failed romance with Aussie actor Liam Hemsworth and a rumored fling with Hollywood womanizer John Mayer. The Arnold and Maria, on the other hand, are taking news of the budding romance with a grain of salt.
“Billy Ray and Tish think Patrick is just the kind of stable guy Miley needs. But Arnold and Maria worry that Miley might lure Patrick into the Hollywood party scene.”

top ten mysterious places

Stonehenge
Who has never heard about Stonehenge? I guess it is one of the most popular mysteries. So, what’s the point about this megalithic wonder? Why does this place cause controversy in the scientific community?

Stonehenge is a megalithic monument on the Salisbury Plain in Southern England, composed mainly of thirty upright stones (sarsens, each over ten feet tall and weighing up to 45 tons), aligned in a circle, with thirty lintels (6 tons each) perched horizontally atop the sarsens in a continuous circle. There is also an inner circle composed of similar stones, also constructed in post-and-lintel fashion. You can say that there are a lot of great monuments all over the world, many of them are more interesting. What is special about Stonehenge? All those questions that have no exact answers. What was its function: an astronomical observatory, a religious site, or something supernatural? Who built it, and how?


Some have suggested that Stonehenge was built by Druids, but we don't really know much about the builders. The archaeology points to a construction date between 5,000 and 3,000 years ago, so it was built even before the first metal tools were used by humankind.

Regardless of who built the stone monument, the design and construction involved thousands of people. To drag huge stones from Marlborough Downs, 30 kilometres to the south of Stonehenge, would have been quite a feat. And how was it possible to erect those stones? It is an amazing feat of engineering, and there are many legends that reflect the inability to explain how the heavy stones could have ever been transported by primitive humans. Stonehenge is even mentioned within Arthurian legend, that names Merlin as the engineer.


One more interesting thing is that Stonehenge is angled such that on the equinoxes and the solstices, the sun rising over the horizon appears to be perfectly placed between gaps in the megaliths. This is doubtless not an accident, and probably contributed to the stories of its mysterious origins.Nazca Lines

Nazca Lines are the most outstanding group of geoglyphs in the world, they are located in the Nazca Desert, between the towns of Nazca and Palpa on the Pampas de Jumana in Peru. Etched in the surface of the desert pampa sand about 300 hundred figures made of straight lines, geometric shapes and pictures of animals and birds - and their patterns are only clearly visible from the air.
There are 3 mysterious aspects to Nazca Plateau:

• First, the straight lines, many kilometers long, crisscross sectors of the pampas in all directions.
• Second, many of the lines form geometric figures: angles, triangles, bunches, spirals, rectangles, wavy lines, etc.
• Third, many lines form animal patterns.

Nazca Lines Map Extract:
It is believed that the geoglyphs were built by a people called the Nasca- but why and how they created these wonders of the world has defied explanation. Since the Nazca lines cannot be recognized as coherent figures except from the air, it is presumed the Nazca people could never have seen their work from this vantage point, there has been much speculation on the builders' abilities and motivations.
Could these geoglyphs be effigies of ancient animal gods or patterns of constellations? Are they roads, star pointers, maybe even a gigantic map? If the people who lived here 2,000 years ago had only a simple technology, how did they manage to construct such precise figures? Did they have a plan? If so, who ordained it? It all seems so otherworldly. To comprehend the Nasca lines, created by the removal of desert rock to reveal the pale pink sand beneath, visitors have proposed every imaginable explanation - from runways for spaceships to tracks for Olympic athletes, from op art to pop art, to astronomical observatories.
Easter Island

Easter Island (Rapa Nui in the indigenous language), is a Chilean-governed island in the south eastern Pacific Ocean. Rapa Nui is a small, hilly, now treeless island of volcanic origin. It's been called the most isolated inhabited territory on Earth, but there is another aspect that sets it apart from any other place on Earth - its hundreds of megalithic human-like statues that face inland from the shore. These enigmatic statues are called moai.

Almost all moais were carved out of distinctive, compressed, easily worked volcanic ash. The largest one weights up to 165 tons, and its height is almost 22 meters. Some upright moai have become buried up to their necks by shifting soils.

This massive production of megalithic works on an island that is absolutely barren, with just grass, immediately captures our imagination. How did it all happen? Who built these statues? And why did they build them?


Some scientists suggest that Easter Island inhabitants, the Rapanui, came from Polynesia. But similarities to Indian stone statues around Lake Titicaca in South America are striking. Is this accidental or not? Scholars are unable to definitively explain the function and use of the moai statues. Some of them suggest that the statues were symbols of authority and power, both religious and political.

One of the biggest riddles about Easter Island is how the statues 'traveled' from the quarry to their platforms or ahus, sometimes as far as 20 or 25 kilometres away? Rapa Nui legend has it that the moai "walked from the quarry". But less than one third of all carved moai actually made it to a final ceremonial ahus site. Was this due to the inherent difficulties in transporting them? Were the ones that remain in the quarry deemed culturally unworthy of transport? Or had the islanders run out of the resources necessary to complete the Herculean task of carving and moving the moai?


Easter Island is more well known as Te-Pito-O-Te-Henua, meaning ‘The Navel of the World’ and as Mata-Ki-Te-Rani, meaning ‘Eyes Looking at Heaven’. These ancient names and a host of mythological details point to the possibility that the remote island may once have been both a geodetic marker and the site of an astronomical observatory of a long forgotten civilization.
