    It's very important that we all recycle.In nature,everything1 again.For example,when an animal dies,it becomes2 animal's food.Nothing is wasted.But humans have created things like plastic bags which can't be3 down by nature.Our4 kills animals and pollutes water and soil.5 we continue making too much rubbish,the problem will only get worse.If nature can't reuse the rubbish,we must recycle6 .We should clean up the rubbish we've made because nature can't.

    Recycling is also the right thing to do for another reason.The earth is rich in natural materials like water and trees,7 these materials are not endless (无尽的).We use up our natural materials8 faster than the earth is able to reproduce (再生) them.For example,each year we cut9 more than 6,000 square miles of forest.But it takes an average of 25 years for a new tree10 .

    Recycling can help us save the earth,so let's take action right now.

    E-waste is fast becoming a serious problem around the world.This report will examine this problem and provide some possible ways to solve it.

    We live in a society that is producing and using electronics (电子产品) all the time.It is often cheaper to buy new products than to repair old ones.Also,through clever advertising,companies always encourage people to change their old TVs,mobile phones and computers for the latest models.E-waste is created when we throw away old ones.In the EU alone,about 8,700,000 tons of E-waste is produced each year.Sadly,just over 1,000,000 tons is recycled.

    Burying (填埋) E-waste or burning it causes setious problems for the environment.Electronics have dangerous things in them.These things can then get into the ground or pollute the air when they are burnt.

    In recent years,  ▲  .However,their plans are not always managed properly.Sometimes electronics are just sent to poor countries such as Ghana.Here they are often burnt in public areas,which is very bad for people's health.Setting up recycling centers is a good way to solve this problem.E-cycling centers could recycle the parts that can be reused and deal with the rest properly.

    Another way is to make producers responsible for their used products.This means that producers must take back old products which are no longer wanted.They should then make suretheyare properly recycled or reused.

    As for us,we should try to cut down on E-waste.Change electronics only when we have to.And don't buy a product just to have the latest model.

    E-waste is a serious problem in the modern world.Both producers and users must take actions and try to keep it to the smallest amount.

    Learning about the environment is very important. There are many good books that will help you learn. To get started, ask your teacher or a librarian for some suggestions. You can also look at some good websites with information about the environment and climate change. Climate change may be a big problem, but there are many little things we can do to make a difference.

    Driving a car or using electricity is not wrong. We just have to be smart about it. Some people use less energy bycarpooling. For example, four people can ride together in one car instead of driving four cars to work. Whenever we use electricity, we put greenhouse gases (气体)into the air. By turning off lights, the television, and the computer when they aren't needed, you can help a lot.

    Don't buy products that use too much energy. Some products, like certain cars, are made specially to save energy. These cars can travel longer on a smaller amount of gasoline. They don't pollute as much, either. Products like computers, TVs, and VCRs with the ENERGY STAR label (标签)Ⓒ are made to save energy. Buying products with these labels will help protect the environment. Buy recyclable products instead of non-recyclable ones. Recyclable products are usually made out of things that have already been used. It usually takes less energy to make recyclable products than to make new ones. So when you go shopping, look for the recycle mark on the package-three arrows that make a circle. The less energy we use, the better.

    How green are you? Do you know how to be green?

    We all need a healthy environment, but we produce waste every day and it does harm to our environment.Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment.Here are some ideas for you.

Reduce

    Reduce means “use less”.Don't waste things.This saves money and reduces pollution and waste going into the environment.Before we buy something new, think whether it is really neces sary or maybe the old one will be just as good! When we do buy things, choose local products if possible, and try not to buy too many things from abroad.

Reuse

    Reuse means "use again".Use things for as long as possible.When we buy things, make sure that they can last a long time.We should look after them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones.Don't use a paper cup or a paper bag.It's better to use a china cup and a lunch box because you can use them again.

Recycle

    Recycle means “change things into something else”.Though it takes energy to change something into something else, it's better than throwing things away or burning them.Find out what can be recycled in your neighborhood and take part in the recycling program.We should also buy products made from recycled materials,such as recycled paper, to help save trees.

    So please remember three words: reduce, reuse and recycle.
