Change for a Better Future
Many readers have written to us about their reactions to the ban on plastic (塑料）bags, which began on the first day of this month. Nearly all said, despite the convenience of super-thin plastic bags, they are still willing to kick the habit because they realize the harm the bags cause to our environment.
(46) And this year’s slogan for World Environment Day is “Kick the Habit! Towards a Low Carbon Economy!” While this theme focuses on climate change and reducing greenhouse gases emission (散发)，the same spirit applies to China’s effort to eliminate the use of highly-polluting plastic bags.
(47) However, the ban on plastic bags is felt strongly among them precisely because of their lifestyle: Plastic bags come in handy (有用的）when the students pick up tea-leaf eggs or pancakes (煎饼）for breakfast while dashing to morning classes. (48)
In addition, the readers suggested that the other habits, the ones many of us barely notice, may also contribute to the deterioration (恶化）of the environment: excessive use of tap water when rinsing (冲洗） washed clothes, leaving the lights on when nobody’s in the dorm, throwing used batteries out with the ordinary trash (垃圾)• (49) They called on others to follow suit. This position by college students is inspiring. (50)
