What if there were no bees? 

    It's a beautiful day for a picnic, but minutes after you spread a blanket on the grass and unpack an impressive selection of sandwiches, fruit salad and a show-stopping cherry pie, you discover an uninvited guest. A bee is making the rounds, buzzing around your head and scaring all your friends. You're about to swipe at the winged interloper with your shoe, but then think better of it. 
      It's a good thing, too, because bee populations are dwindling. Consider these United States Department of Agriculture (USDA) survey results, based on 21.7 percent of the 2.6 million bee colonies in the United States. During the 2013-2014 winter, more than 23 percent of honeybees in the managed colonies included in the survey had died. The winter before that was even worse, when more than 30 percent of the hives died [source: Jones].  
     And honeybees aren't the only bees at risk. There are more than 20,000 species of bees in the Hymenoptera order that are crucial to life as we know it [source: Encyclopedia Britannica]. So what would happen if there were no bees at all?
     Bees rely on pollen and nectar from plants for food. The nectar is later transformed into honey and the pollen is transferred from plant to plant as the bees travel, resulting in crosspollination. In fact, bees pollinate as much as 70 percent of the planet's top 100 food crops, including apples, avocadoes, cucumbers, nuts, squash and more [source: Greenpeace].
     Many of the diverse flavors and nutritional components in our food are the direct result of bees at work. And, without the crucial role bees play in agriculture, the world's food supplies would likely suffer. That's because an estimated one-third of all the food we eat relies on bees to flourish. Some of the foods we eat simply wouldn't exist without bees. Almonds, for instance, rely entirely on bees for pollination. In California alone, the almond crop needs 1.4 million bee colonies for successful pollination [source: USDA]. 
     If there were no bees, our food supply would be less varied and less available. While we might not go extinct, we would certainly need to find edible alternatives to many of the mainstay foods we currently enjoy -- particularly those crops dependent on bees for pollination -- and figure out ways to stave off economic hardship and famine until new cultivation methods could be developed.

10 Ways to Protect Your Privacy Online


Source: www.newsweek.com (Adapted) Oct, 22nd 2010




    Up to a couple of years ago, I used to say that the average person could protect his or her privacy on the Web. Even as the founder of an online reputation-management company, I believed it was possible – so long as you were willing to commit some time doing it. Today, I tell people this: the landscape of personal data mining and exploitation is shifting faster than ever; trying to protect your online privacy is like trying to build your own antivirus software – really, really difficult. But whether or not you have the time (or money) to invest in the pros, there are a few simple steps we can all take to reduce the risk to our private data.


1. Do not put your full birth date on your social-networking profiles.


Identity thieves use birth dates as cornerstones of their craft. If you want your friends to know your birthday, try just the month and day, and leave out the year.

2. Use multiple usernames and passwords.

Keep your usernames and passwords for social networks, online banking, e-mail, and online shopping all separate. Having distinct passwords is not enough nowadays: if you have the same username across different Web sites, your entire life can be mapped and re-created with simple algorithms.

3. Shred. If you are going to throw away credit-card offers, bank statements, or anything else that might come in hard copy to your house, rip them up into tiny bits first.

According to the author, the year of your birthday must be

What can you expect in El Niño conditions? Warmer sea-surfaces that could send floods to South America, potentially impacting farmers and confounding food production, among other things.
