Dear Mayr,I’m glad t write this letter t yu. I’d like t talk abut the envirnment in ur city.Our city is nt as beautiful as befre. Envirnmental prblems are becming mre and mre serius. The river is dirtier. Peple are thrwing litter int the river r in public places like parks. This is turning beautiful places int ugly nes. Factries are putting waste int the river and they burn cal, which als pllute the air with a lt f black smke. And mst f us ride in cars t schl even if they live clse t schl. I think it is time t play a part in saving the earth.First f all, we shuld let mre peple knw the imprtance f envirnmental prtectin. We’re suppsed t save water and energy in ur daily life. Secnd,t cut dwn air pllutin, we shuld ride a bike r walk t schl instead f riding in cars. If it’s far, we can take the bus r subway. Third, we shuldn’t thrw litter here and there. We shuld put it in the bins. As fr waste pllutin, we shuld never take wden chpsticks r plastic frks when buying takeaway fd. We can als use reusable bags instead f plastic bags. What’s mre, the gvernment shuld clse dwn the factries that are putting waste int the river r giving ut a lt f black smke.The earth is ur hme and we have the duty t take care f it fr urselves. S I hpe that yu can take my advice. Thank yu.
