Nothing is isolated in human society, everything always goes together to support each other. So from the time students know they come to school, there will be bags born. Since people knew how to use pens and rulers for study and work, pens and rulers also appeared from there. Pen tube – a very familiar tool for students, but to fully understand it, we need to consider many aspects.


Compared to the history of ballpoint pens, eyeglasses or some other items, the pen holder is not mentioned much. Although there is no definite date, it can be affirmed that the pen tube was born in parallel with the time of the pen's birth. According to some historical records, in the Middle Ages, poets, historians... used a pen holder shaped like a flower vase to stick brushes. This pen tube is made of porcelain with decorative patterns on the outside, but it is only placed on letters and is very inconvenient to move. Perhaps that is why horizontal pen cases were born later.


However, at present, environmental problems are a burning problem of many countries in the world today, including Vietnam. Every year, millions of tons of waste and waste are discharged, not only negatively impacting the environment but also affecting human health. If they are reused, it will bring economic efficiency and significantly reduce the amount of waste. So, recycling old plastic to create beautiful and unique things in the family can help protect our environment.


We can find enough materials to make a pen holder such as: A piece of cardboard about 15cm long, about 20cm wide. Colored paper, scissors, glue, staplers, dried flowers,... Remember those plastic bottles? It would be the perfect material for a beautiful fountain pen. Unlike in the past, today the materials for making pen tubes are extremely diverse. It is everything around us that can be used. Although very diverse in types, but in general, the pen tube has two parts: the outer shell and the hollow core to hold the pen.


Thanks to it, students can arrange learning materials such as pens, rulers, compasses, pastels, sticky notes, etc. neatly. Not only that, the pen holder also has the function of protecting the pen and ruler safely. It will be the companion of students, students and some other professions. For us, it is not only a place to store essential items but also a place to hide memories. Therefore, each of us must cherish this object and keep it carefully.


It only takes a little time to have a small pen holder in the study corner that looks beautiful and convenient. School age with white shirt and future aspirations cannot be without such good friends. Let's create a companion for us, for our environment, for the life of humanity.

Today, I would like to talk to you about a product that not only helps us keep our stationery organized, but also contributes to environmental protection. That product is the recycled paper pen box.

As we all know, paper is one of the most commonly used materials in our daily lives. However, the production of paper consumes a large amount of natural resources and energy, and also generates a significant amount of waste and pollution. Therefore, it is important for us to find ways to reduce our consumption of paper and to recycle it whenever possible.

The recycled paper pen box is a great example of how we can contribute to this effort. Instead of using new paper to make the pen box, this product is made from recycled paper, which helps to reduce the demand for new paper and the associated environmental impact. In addition, the production process for the recycled paper pen box consumes less energy and generates less pollution compared to the production of new paper products.

Furthermore, the recycled paper pen box is not only environmentally friendly, but also practical and durable. It provides a convenient and organized way to store and carry pens, pencils, markers, and other stationery items. Its sturdy construction and attractive design make it a great addition to any desk or workspace.

In conclusion, the recycled paper pen box is a simple yet effective way for us to contribute to environmental protection in our daily lives. By choosing products made from recycled materials, we can help reduce the demand for new resources and minimize the environmental impact of our consumption. I encourage all of you to consider using the recycled paper pen box and other recycled products whenever possible. Thank you for your attention.

Enviroment is neccessary thing for this life. Enviroment is the air we breath, the water people drink and is everything they need for their life. But now the most important thing for the life is being polluted. This pollution affects the health of all living things. Air is damaged by lorry fumes and car, and power stations create acid rain which can destroys entire lakes and forests. When fossil fuels: gas, oil and coal are burned to provide energy for cooking, lighting etc. they form polluting gases. Not only on land but also in the sea, oils spills pollute sea water and kill marine life; chemical waste from sewage works and factories, and artificial fertilisers from farmland, pollute river water, spreading disease, and killing wildlife. Everything is being caused by human’s existence. Humans create rubbish! Each household produces about one tonne of rubbish each year! Most of this is taken away by dustmen and burned in incinerators or buried in enormous landfill sites – both of these actions can be dangerous for our environment.

But only people can change and solve it. Pollution could be prevented by all thing we do each day. First people can use recycled paper to save trees. Second try to avoid using plas. It is hard to recycle. People should refuse to use carrier bags. If people can not avoid buying plas bags, they should use re-use plas bags many times. Finally people must take their old clothes to charity shops. People also should save energy to protect environment. Switching off all electric things when they are not in use, walk or use a bicycle instead of car for short trips, keep healthy life and  keep clean atmosphere.

Keep clean environment isn’t only all ways are mentioned before but also to protect natural resources. That is the way to conserver wild life. First we need to conserve the old forest, rainforest, build more safari and national park, and plant more trees to make place to live for wild animals. Second we need to prohibit hunters who hunt animals too many out of the law allowance.

Finally, we now know that enviroment is the most important thing for life and we know how to protect and use it scientifically. Everyday we invent and find more and more way to protect enviroment. I hope that in the future the earth will be cleaner.
