My part in environmental protection
With the development of the technology, the living standard of the people increased a lot. But as a saying goes:‘Every coin has two sides’. It also brings bad things. One of the most serious problems is the serious pollution of air, water and soil. The polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities.
Since we have only one earth, we must do something to protect it. For me, first, I will appeal to the government to take even more concrete measures. The government should let people fully realize the importance of environmental protection through education. Then, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves. Second, I will take a bag to shop and not use the plastic bag to hold the goods. Third, I will never use the one-off chopsticks, lunch box, because those stuffs can not only pollute the environment, but also made of unrecoverable material. Last, I will tell my family members and friends to work together for environment protection. As we all know, the individual power is limited, but the collective power are unlimited.
