A possible version:
For a time, disposable chopsticks(一次性筷子) became popular, which caused great damage to forests. But since our country began to ban the use o fthem in 2004, things have changed.
As is vividly shown in the left cartoon, in the past disposable chopsticks made of wood were often used in our daily life. It is a waste of wood and does harm to the environment. Due to the abuse of disposable chopsticks, many trees were cut down, which resulted in the decrease of the forest.
Since 2004, with the ban of using disposable chopsticks and the awareness of forest protection, people begin to reject using disposable chopsticks. Our government has also taken measures to prevent factories from producing such chopsticks and attach importance to forest conservation. Now disposable chopsticks are out sight and more trees appear..
This teaches us a good lesson. In our daily life, we should try to use less wood and plant more trees so that our resources can be sustainable and our world can be a better place to live in.
