Dear Sir or Madam,
I am writing to ask for your help in protecting forests around the world.
Forests are home to many animals and plants. Moreover, they help clean the air and provide us with oxygen.
But forests are disappearing quickly. People are cutting down trees to make way for farmland and buildings as well as everyday products such as paper. Pollution is another problem for forests. Rubbish and waste from homes and factories are harming the plants and animals living there.
Writing
Sample
Together we can help solve these problems. We can protect our forests by planting new trees. We can also recycle and reuse everyday products to reduce waste. Moreover, we can share our ideas and let others know about the importance of protecting forests.
It is time for us to take action. I hope we can work together to help protect forests.
Yours faithfully,
Lu Jiang
