In our daily life， much plastic package is used just once and then thrown away． According to a new study from the University of California， 9% of this is recycled， 12% is burnt and 79% goes to landfill． And because most plastic doesn't biodegrade， once it's in the ground， it stays there． （1）The study also shows that eight million tons of plastic waste are pouring into the sea every year．

    Scientists have calculated the total amount of plastic ever made： 8.3 billion tons． That's as heavy as one billion elephants． And almost all of it has been made in the last 65 years．

    What can we do as students？ Just say no to single﹣use plastics like straws， cups and bags． Many people love to drink from a straw or use plastic to carry things， but they are really bad for the environment．

    （4）Bring your own chopsticks if you're planning to eat outside． It can be hard to remember．

    Just put a pair of chopsticks in your bag before you leave home．

    You know you're going to need some water to get you through your day． So carry a bottle（or a cup） with you． （5）That will help you avoid plastic bottles．
