palladium as a word in the sentence is still difficult to understand. Maybe if I try using more simple words, it will be clearer for you.

So I’d like to tell you about the smog again.
Since last winter, smog occurred many times. It has really hurt our daily life. Many traffic accidents happened because of heavy smog weather. Also, a lot of people had to go see their doctors due to serious diseases caused by smog.

Even more people have to stay at home to avoid the toxic air from smog. People have realized how much harm smog causes and the importance of protecting our environment. Many people are taking measures to reduce the bad weather. The government recommends people to work or school with public transport, such as bus and underground. Also planting more trees is important.

According to me, I will ride on bicycle or walk to school. I won’t throw everything away in my pocket. Besides, I will tell the people I meet to protect the environment wherever possible as much as they can. Would you like to ask some good ideas? I am looking forward to hearing your reply.
Your humble
李华
