Do you know that a student can produce up to 240pounds of school waste and lots of waste gas (气体) during a term?This includes transportation,food,paper,pens,pencils and so on.
Transportation
Some parents drive their kids to school every day.We all know waste gas from cars is a main cause air pollution.If parents who live in a neighborhood can take turns to drive their kids to school each day,that'll be better.Another way of going green is to walk to school if students live near their schools.
Food
It's surprising that only one elementary school can produce up to 19,000pounds of lunch waste each year.That's 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
Lots of paper is thrown away by American students.They throw away about 1.6billion pens every year.They waste many pens and chemicals (化学药品) in them are bad for the environment.Many more pencils are thrown away than pens.Pencils are made from trees,so if more pencils are thrown away,more trees will be cut down.So students should reuse (再使用) 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 lots of money and materials if they reuse the same schoolbags each year.
