Do you know that a student can produce up to 240 pounds of school waste and lots of waste gas during a term? This includes transportation, food, paper, pens, pencils and so on.

Transportation

Many parents like driving their kids to school every day. We all know waste gas from cars is a main cause of air pollution. If parents who live in a neighborhood can drive their kids to school by turns each day, that’ll be better. Another way of going green is to walk to school if students live near it.

Food

It is surprising that only one primary school could produce up to 19,000 pounds of lunch waste each year. That is only one school. One way to help take care of the environment is to stop using plastic bags. There are all kinds of environmental boxes for students to put their food in.

Paper, pens and pencils

A lot of paper is thrown away by American students. They throw away about 1.6 billion pens every year. They waste many pens and the chemicals of them are bad for the environment. Much more pencils are thrown away than pens. Pencils are made of trees, so if more pencils are thrown away, more trees will be cut down. So students should reuse paper, pens and pencils instead of throwing them away.

Backpacks

As fashion comes and goes, almost every kid needs a new backpack every year. They can save a lot of money and materials(材料)if they reuse the same schoolbags.

Are you carrying too much on your back to school? I'm sure lots of children of your age will say "yes". Not only the students in China have this problem, but also children in the USA have heavy schoolbags.

Doctors worry that children are having back and neck problems because their schoolbags are too heavy for them. "It's hard for me to go upstairs with my bag because it's so heavy!" said Rick, an 11-year-old student in the USA.

But how much is too much? Doctors say students should carry no more than 15% of their own body weight. Scott Bautch, a back doctor, says children under Grade 4 hould stay within 10 %. But it is also important that other children don't stay with over 15%, because their bodies are still growing. Parents and teachers are starting to tell children to only take home the books they will read that night. Some teachers are using pieces of paper or thin workbooks instead of thick ones.

One of the best way to solve the problem is, as some children said, to have not homework at all!
