Many kids turn up their noses at the though of eating fish because, well, it can smell “fishy”. While it is usually a healthy source of protein in the diet, there may be several reasons to avoid biting into a forkful of fish. Before you break out the tartar sauce, learn some facts about fish to keep yourself and the environment healthy.
Some fish may contain harmful chemicals, which can be the result of both natural causes and water pollution. Mercury is a toxic chemical, which occurs naturally in oceans and the Earth's crust, but also comes from man-made sources, such as pesticides, burning garbage, and the releasing of fossil fuels.
Polychlorinated biphenyls（PCBs），a group of chemicals, can also be found in some fish. These man-made chemicals were used in many industries until 1977, when they were banned. PCBs were released or leak into the air and water and have been transported around the globe.
How do mercury and PCBs end up in fish and the food supply? When they are released into the air, they attach themselves to particles. These particles settle on the ground and in the water and are eventually eaten by microscopic organisms. Small fish eat the micro-organisms, and large fish eat the small fish and on up the food chain.
Because they can negatively affect your health, the U.S. Environmental Protection Agency advises that kids younger than 16 years old avoid fish that contain high levels of mercury and PCBs. These include shark, swordfish, king mackerel, and tilefish.
There are also many types of fish that are good for you, but because of over fishing some are in danger of being wiped not. Some are being fished in the wild so much that they cannot reproduce enough to survive. Others are being farmed in ways that are not environmentally friendly. These fish include red snapper, Atlantic salmon, blue fin tuna, and king crab.
Despite these problems, there are several fish that are both healthy and sustainable, such as Alaskan salmon, American catfish, Pacific cod, and several farm-raised fish and shellfish.

Sooner or later, many families will face the situation of moving. The experience can be very bad for kids, who may not be a part of the decision to move and may not understand it. You can take steps to make the whole process (过程) easier for everyone.
Many kids like to stay in familiar places. So as you consider a move, weigh the benefits (好处) of that change against the comfort that neighborhood, school, and social life give your kids. If your family has recently dealt with a big life change, such as death, you may want to put off a move to give your children time to accept the fact.
The decision to move may be out of your hands, perhaps because of a new job or money problems. Even if you’re not happy about the move, try to keep a positive (积极的) attitude to it. During the move, a parent’s attitude can greatly influence kids.
No matter what the results are, the most important way to prepare kids to move is to talk about it. Try to give your children as much information about the move as possible. You can ask kids to join in the planning such as house-hunting or the search for a new school. This can make the change feel less like it’s being forced (被迫) on them. If you’re moving across town, try to take your children to visit the new house and th
e new neighborhood.
A move can have many problems, but good things also come from this kind of change. Your family might grow closer and you may learn more about each other by going through it together.
