In an effort to discourage people from using plastics, scientists have been hard at work inventing alternative packaging products.

The idea of using seaweed（海草） to make eco-friendly water bottles has been around for a few years. Recently, Ari Jonsson took his invention—a water bottle made from red seaweed—to show off at a festival. The bottles will only hold their shape as long as they are filled. As soon as these bottles are empty they will begin to break down, though they would be perfectly safe to eat. Ari Jonsson's bottles are a step closer to a widely used alternative to the current plastic ones.

The eatable water container is not the only product to add to our image of the future. Narayana Pessapaty has also created eatable spoons. After the success of his spoons, Mr. Pessapaty is ready to expand and introduce forks and chopsticks to his menu. His aim is to largely reduce the amount of plastic waste, which is a huge problem for waste sites all over the world. It is a product that may take up to 500 years to break down, and recycling companies worldwide are struggling to deal with it.

Aside from the obvious benefits to the environment, this new packaging is also cheap to produce and therefore cheap to buy. Even better is the fact that similar eatable cutlery can be made at home, possibly a science project for children or just fun with friends. Why not experiment and create your own recipes?

Last year, during the summer holiday, I found part-time job, worked in a toothbrush factory at night. Not until I experienced it did I realized that it was no easy job.I went to work when my parents were going to bed. On the morning, when my parents were going to work, I came to home to sleep. This backward schedule was very tough for me that I often felt tiring. But I am glad that I had this unforgettable experience. Not only is it fun to “rise and shine” along with the moon or stars, but also I had learned to appreciate the hard work of those which are working while the rest of us are sleeping.

Many people like eating junk foods, because they thought they are delicious. But in fact, these foods are not healthy. That we need most is a balanced diet. Eating a balanced diet mean choosing a wide variety of foods from all the food groups. A balanced diet provides different kinds of nutrition(營養(yǎng)) with our body. We need a balanced diet to keep healthy. Therefore, many people still have unhealthy eating habits, that will do harm to their health. I think is necessary for us to have three meals a day properly. When eat, we should eat different kinks of foods. For an example, we should eat both meat and vegetables to get different kinds of nutrition.
