During the school year many parents take on the role of driver as they drive their children from one lesson to another. It can be understood that many of us want our children to have a little taste of everything, from organized sports to music, dance and more. But we overdo it, leaving our children feeling a little tired, and according to parent educator Diane Loisie, it’s their school work that suffers the most. “After school, if they’re busy in a number of sporting events, besides they need to do their homework, then the time they’ll feel sleepy is in the classroom. Your child needs free time. So if you’re filling up that after school time, then it’s during the day they’re going to be taking a break. ”

Professor Claire McDermott agrees that there’s a lot to be gained from sometimes putting those planned lessons and activities away. “Relaxing time is important for children. It’s time just to do the things they want to do. A child can go up to their room, or they can play around. It doesn’t look like useful time; parents certainly wouldn’t be saying ‘Wow, are they ever learning things now?’ But this relaxing time gives both the body and the brain just a wonderful chance to relax after a day. It helps a child prepare for sleep, but it also helps to understand the learning that’s gone on that day. ”

It’s hard to prevent signing our kids up for some activities and lessons. After all, many of us want our children to have a head start in life and the chance to join in great activities in the arts or sports is a part of that. However, Loisie feels that in the long run most children feel better with just a few key activities because it gives them an opportunity to master them. “When we get our children in too many activities because we want our children to experience everything, then what we’re doing is setting them up not to be good at one thing or gaining a skill. ” So choose your children’s activities wisely. It may be one of the best things you’ve ever done for your kids… and for the family driver!

Imagine a mass of floating waste is two times the size of the state of Texas. Texas has a land area of more than 678 000 square kilometers. So it might be difficult to imagine anything twice as big.

All together, this mass of waste flowing in the North Pacific Ocean is known as the Great Pacific Ocean Garbage Patch. It weighs about 3 500 000 tons. The waste includes bags，bottles and containers—plastic products of all kinds.

The eastern part of the Great Pacific Ocean Garbage Patch is about l 600 kilometers west of California. The western part is west of the Hawaiian Islands and east of Japan. The area has been described as a kind of oceanic desert，with light winds and slow moving water currents. The water moves so slow that garbage from all over the world collects there.

In recent years，there have been growing concerns about the floating garbage and its effect on sea creatures and human health. Scientists say thousands of animals get trapped in the floating waste，resulting in death or injury. Even more die from a lack of food or water after swallowing pieces of plastic. The trash can also make animals feel full，lessening their desire to eat or drink.

The floating garbage also can have harmful effects on people. There is an increased threat of infection of disease from polluted waste，and from eating fish that swallowed waste. Divers can also get trapped in the plastic.

Its existence first gained public attention in l997. That was when racing boat captain and oceanographer Charles Moore and his crew sailed into the garbage while returning from a racing event. Five years earlier，another oceanographer learned of the trash after a shipment of rubber duckies got lost at sea. Many of those toys are now part of the Great Pacific Ocean Garbage Patch.

In August，2009，a team from the University of California，San Diego became the latest group to travel to it. They were shocked by the amount of waste they saw. They gathered hundreds of sea creatures and water samples to measure the garbage patch’s effect on ocean environment.
