Dearest darling girl,

    Today is the beginning of the next stage in your life. We head off to your new home at Stanford. Where do I start in telling you how proud I feel to be called Mummy by you? We've laughed at how you burst into this world with a scowl on your face, how determined you have always been right from feeding yourself to making big decisions for your life. There were days during your illness that I wasn't sure you had the will to make it. Telling you that you needed to want to get better was the hardest and yet the greatest day. From that day you took responsibility and decided you wanted to beat anorexia（厌食症）．

    I don't think I've ever felt so proud of you as when you came home to say that you wanted to go to West Africa between school and university. You chose to go alone, and to raise the money yourself. You have such strength of character and determination. It is at times hard to believe that you are only 18. You experienced something in that month that few dare experience in a lifetime.

    So, Viv, here are my words of wisdom to you as you start your next big adventure. The world is a beautiful place but often a few things can make it seem difficult. God's temple is made of love. It's man's temple that is built of stones. Open your heart to goodness and never ever let negative people or thoughts take hold of you. As Minor Myers put it, "Go into the world and do we'll. But more importantly, go into the world and do good:'

    It is true that with every passing day, I will grow older and weaker. A day may come when I will become forgetful. But even then, you with your bright smile, will light up my heart.

Your Alo

    Ever wonder how much a cloud weighs? What about a hurricane? A meteorologist（气象学家） has done some estimates and the results might surprise you.

    Let's start with a very simple white puffy cloud—a cumulus cloud(积云). How much does the water in a cumulus cloud weigh? Peggy LeMone, senior scientist at the National Center for Atmospheric Research in Boulder, Colorado, did the numbers. “The water in the little cloud weighs about 550 tons,” she calculates. “Or if you want to convert it to something that might be a little more meaningful...think of elephants.” Assume（假设） an elephant weighs about six tons, she says, that would mean the water inside a typical cumulus cloud would weigh about one hundred elephants.

    The thought of a hundred elephants' worth of water floating in the sky begs another question—what keeps it up there?

    “First of all, the water isn't in elephant-sized particles(微粒); it's in tiny tiny tiny particles,” explains LeMone. And those particles float on the warmer air that's rising below. But still, the concept of so much water floating in the sky was surprising even to a meteorologist like LeMone. “I had no idea how much a cloud would weigh, actually, when I started the calculations（计算）,” she says.

    So how many elephant units of water are inside a big storm cloud—10 times bigger all the way around than the “puffy” cumulus cloud? Again, LeMone did the numbers: About 200,000 elephants.

    Now, come to the calculations for a hurricane about the size of Missouri and the figures get really massive. “What we're doing is weighing the water in one cubic meter theoretically pulled from a cloud and then multiplying by the number of meters in a whole hurricane,” she explains.

    The result? Forty million elephants. That means the water in one hurricane weighs more than all the elephants on the planet. Perhaps even more than all the elephants that have ever lived on the planet.

    Have you ever wondered why people drive on a different side of the road? It might seem bizarre that U. K. drivers stay on the left, but they're not the only ones. Around 35 percent of the world population do the same, including people in Ireland, Japan, and some Caribbean islands.

    Originally, almost everybody traveled on the left side of the road. However their way of transport was quite different from today: Think about four legs instead of four wheels. For Medieval swordsmen on horseback, it made sense to keep to the left to have their right arms closer to their enemies. Getting on or off was also easier from the left side of the horse, and safer done by the side of the road than in the center.

    So why did people stop traveling on the left? Things changed in the late 1700s when large wagons (货车) pulled by several pairs of horses were used to transport farm products in France and the United States. The wagon driver sat behind the left horse, with his right arm free to use his whip to keep the horses moving. Since he was sitting on the left position, he wanted other wagons to pass on his left, so he kept to the right side of the road.

    The British Government refused to give up their left-hand driving ways, and in 1773 introduced the General Highways Act, which encouraged driving on the left. This was later made law thanks to The Highway Act of 1835.

    When Henry Ford showed his Model T in 1908, the driver's seat was on the left, meaning that cars would have to drive on the right hand side of the road to allow front and back passengers to exit the car onto the roadside. However, British drivers remain on the left, and this is highly unlikely to change.

Unusual incidents are being reported across the Arctic. Inuit(因纽特人) families going off on snowmobiles to prepare their summer hunting camps have found themselves cut off from home by a sea of mud. There are also reports of sea ice breaking up earlier than usual, carrying seals beyond the reach of hunters. Climate change may still be a rather abstract idea to most of us, but in the Arctic it is already having great effects—if summertime ice continues to shrink at its present rate, the Arctic Ocean could soon become almost ice-free in summer. The knock- on effects(连锁反应) are likely to include more warming, cloudier skies, and higher sea levels. Scientists are increasingly eager to find out what's going on in the Arctic.

    For the Inuit the problem is urgent. They live in unsteady balance with one of the environments on earth. Climate change, whatever its causes, is a direct danger to their way of life. Nobody knows the Arctic as well as the locals, which is why they are not content simply to stand back and let outside experts tell them what's happening. In Canada, where the Inuit people are trying hard to guard their hard-won autonomy in the country's newest land, Nunavut, they believe their best hope of survival in this changing environment lies in combining their ancestral knowledge with the best of modern science. This is a challenge in itself.

    The Canadian Arctic is a vast, treeless polar desert that's covered with snow for most of the year. Adventure into this area and you get some idea of the hardships facing anyone who calls this home. Farming is out of the question and nature offers few pickings. Humans first settled in the Arctic a mere 4,500 years ago, surviving by taking advantage of sea first. The environment tested them to the limits: sometimes the settlers were successful; sometimes they failed and disappeared. But around a thousand years ago, one group appeared that was uniquely well adapted to deal with the Arctic environment. These Thule people moved in from Alaska, bringing dogs, iron tools and the like. They are the ancestors of today's Inuit people.

    Life for the descendants(后代) of the Thule people is still tough. Nunavut is 1.9 million square kilometers of rock and ice, and a handful of islands around the North Pole. It's currently home to 2,500 people, all but a handful of them Inuit. Over the past 40 years, most have abandoned their nomadic(游牧的) ways and settled in the area's 28 isolated communities, but they still rely heavily on nature to provide food and clothing.

    Supplies available in local shops have to be flown into Nunavut on one of the most costly air networks in the world, or brought by supply ship during the few ice-free weeks of summer. It would cost a family around ￡7,000 a year to replace meat they obtained themselves through hunting with imported meat. Economic opportunities are few, and for many people state benefits are their only income.

    It's true that many dads in the wild aren't interested in parenting, but there are some that work pretty hard to give their little ones a good start. Maybe one of these dads will make you remember your own dad!

    The male giant water bug (雄性负子蝽) doesn't seem to mind a heavy load (负荷物) on his back for his kids. The female puts about 100 to 150 eggs on the back of the male, and then she leaves. Once the female is gone, the male has to look after the eggs. It usually takes one to two weeks for the eggs to hatch (孵化). The father giant water bug jumps around to make sure the growing eggs get enough air and water. All this time he can't fly because of the weight of the eggs growing rapidly on his back.

    Now let's turn to the male stickleback fish. When the mother leaves after laying her eggs, the father tends his young. If the young fish go too far away, their father helps with their safe return by carrying them back in his mouth. The male stickleback looks after all his young — as many as 100 — until they can live on their own.

A similar example can be found in emperor penguins (帝企鹅) living in cold areas. The male emperor penguin goes without food while looking after his egg until it hatches. For about 62 to 67 days, the egg stays on top of the father's feet, in very cold temperatures that drop down to -39℃. As a result, the father may lose nearly 50 percent of his body weight while waiting for his baby penguin to be born!

    Russ Gremel, now 98 years old, decided it was time to donate $2 million to the Illinois Audubon Society, a charity to purchase nearly 400 acres of land for wildlife protection. Gremel was able to make this amazing donation because he purchased $1,000 worth of Walgreens stock seven decades ago whose value has grown recently.

    "A single man with no kids, Gremel has lived in the same Chicago house for 95 years, and has always lived simply", neighbor Patrick Falso told TODAY. Falso said he heard Gremel say many times the "money wasn't mine to begin with" and that he always intended to give it away.

    The Gremel Wildlife shelter was founded on June 4. Illinois Audubon Society president Jim Herkert said Gremel's donation was extremely generous. "It's allowing us to protect a really valuable and important possession and realize one of Gremel's wishes that we could find a place where people could come out and experience nature the way he did as a kid," Herkert told TODAY.

    After doing all this, this past weekend, Gremel adopted an old Chihuahua（吉娃娃犬）. Winnie the dog was picked up as a homeless dog several months ago. She suffered from a kind of cancer, which was treated—and all she needed was a loving home, which Colleen Collins, the founder of Perfect Pooches Adoption Agency, was determined to find.

    Gremel had lost his own beloved Chihuahua earlier this year. When he reached out to Collins about Winnie, she felt this could be a good match. That feeling grew when she brought Winnie to his house for a meet and greet, and Winnie was introduced not only to Gremel but also some of his friends and neighbors. One had brought over a lot of fresh strawberries; all said they'd be there to help out in any way needed.
