Read the passage, then answer the questions.
Every day of the year throughout the world, about twenty million paper bags and newspapers are screwed and thrown away
Making paper requires a lot of wood pulp and the work of million of workers. Many countries have had plans to recycle waste paper to save money and labor. In countries where there is the cooperation of the public, paper mills recycle as much as sixty percent of waste paper. Their simple work is to take away the ink, crush it and make it into pulp again. For every ton of recycled newsprint, twelve trees can be saved. We can insist that the more paper people save, the more trees are preserved.
