As any working mum can tell you, running a business and a family at the same time is an almost impossible act. There are never enough hours in the day and most days spill well into the late evening hours. My story starts with a simple red bump (小包)on my back. Turns out, the bump was actually skin cancer! The diagnosis hit me like a ton of bricks. I was in my mid-20s and living a very healthy life. Cancer at that point was unimaginable. And, yet, it was all too true. After crying and crying for days, I finally decided to do something positive about my skin cancer diagnosis. After researching, I knew scientists had found that UV(紫外线)exposure as a child leads to skin cancer later in life—especially for fair skinned people—and I did not want my children to suffer the same fate. So, I decided to quit my job and start my own business. Thus was born SwimZip swimwear—stylish swimsuits with protection that block 99% of those nasty cancer causing UV rays. These cute, sun protective clothes can actually save lives! The choice to follow my passion and help prevent children from getting skin cancer was an easy one, but turning that passion into a successful business, while being a full-time mum, was a whole different story. Being a mum and business owner has been very difficult. I often feel like I cannot ever give as much energy to parenting or working as I would like. After several busy work days, I know I have to take a break, leave the phone at home, and just go out and give 100% to my child. Of course, by the time I get back to being CEO, the "to-do" list has grown enormous again. Late (late, late, late!)nights are the norm . Starting a business from the ground up, and while parenting full time, has been an enormous challenge.

Brain drain, which is the action of having highly skilled and educated people leaving their country to work abroad, has become one of the developing countries' concern. Brain drain is also referred to as human capital flight. More and more third world science-and-technology-educated people are heading for more prosperous countries seeking higher wages and better working conditions. This has of course serious consequences on the sending countries. While many people believe that immigration is a personal choice that must be understood and respected, others look at the phenomenon from a different perspective. What makes those educated people leave their countries should be seriously considered and a distinction between push and pull factors must be made. The push factors include low wages and lack of satisfactory working and living conditions. Social unrest, political conflicts and wars may also be determining causes. The pull factors, however, include academic freedom and extensive funds for research. Brain drain has negative impact on the sending countries' economic prospects and competitiveness. It reduces the number of dynamic and creative people who can contribute to the development of their country. Likewise, with more entrepreneurs (企业家)taking their investments abroad, developing countries are missing an opportunity of wealth creation. This has also negative consequences on tax revenue and employment. Most of the measures taken so far have not had any success in softening the effects of brain drain. One option is to provide adequate working and living conditions in the sending countries. Another option should involve encouraging the expatriates (侨民)to contribute their skill to the development of their countries without necessarily moving back home.

For centuries Dutch engineers have been fighting a war against water. Their main enemy is the sea. A large part of the country is below sea level. In fact, Holland is also called the "Netherlands" which means "low land. " Very tall and strong walls, called dykes, have built to keep out the sea. But in very rough weather the sea may suddenly burst through a dyke. Great damage can be caused by floods when this happens. Three large rivers are also part of the problem. They flow through Holland into the North Sea. They have cut many passages across the country. At low tides, the rivers flow into the sea as usual. But at high tide, the sea can flow into the rivers! This is because the land is so low. The battles against the water never end, but they have made Holland a bigger and bigger country. In order to prevent floods, the engineers take, or reclaim, land that was under water. The Dutch have been reclaiming land for seven hundred years. Land is usually reclaimed from a passage between islands. Two dykes are built across the passage, so they block the water between them. Then the engineers dig long canals and pump the water into them. At low tide, the canals empty the water into the sea. Because the land is so low, water from the sea and rivers can rise up through the ground. For this reason, the pumps continue working. The dykes contain gates, and through these the water is pumped out. In many parts of Holland, pumps must be working all the time. If they stopped, there will be very bad floods. A piece of reclaimed land is called polder , and Holland has thousands of polders. Some are very large, but others are quite small. There are farms on many of the polders. Corn and other crops grow well on the drained land, and it gives good grass for cattle. Many small towns and villages stand on polders. Even Amsterdam's great airport was built on reclaimed land.

We do not often consider how much energy goes into creating comforts like hot showers and cold beer. A more efficient refrigerator will give us the same cold beer while using less energy. A more water-efficient showerhead will give us the same hot shower while using less water: less water requires less energy. By being more efficient, we use less energy, requiring fewer resources and less money. We have a lot of opportunities for energy efficiency at home. Whether you are ready to upgrade an appliance to an ENERGY STAR rated model or replace conventional light bulbs with more efficient ones, you will enjoy the same level of comfort in your daily life while saving both energy and money.
