To learn to write a report on an environmental issue.
Look at the title and the picture and discuss the questions.
What do you know about the Li River Have you ever been there
I know that the Li River is one of the most beautiful and popular river landscapes in China. It is over 100 miles long and is surrounded by the famous karst (喀斯特) mountain formations.
2. What do you think might have caused water pollution in the Li River
As the Li River is very popular with tourists, I think the pollution may have been caused by tourists and tour boats on the river.
Read the report and then answer the questions.
What were some of the negative effects on the Li River as a result of the growth in tourism
Negative effects from the growth of tourism on the Li River include garbage being thrown by tourists and kitchens on tour boats dumping cooking oil into the river. Because of the success of tourism, the population and number of enterprises also rose, meaning there was more waste going into the river.
2. What measures have been taken to improve the LI River’s water quality
Waste water treatment, household waste collection and transport facilities have been improved. Dozens of polluting businesses were moved or closed. New rules about waste disposal and fines for abusers were introduced. Authorities used the media to spread awareness of the issue.
3. What is the “River Chief System”
The “River Chief System” holds senior officials responsible for reducing water pollution.

What is the issue Why does it need to be dealt with
Where does the issue occur What are its causes What effects does it have
What actions have been taken so far What future actions are planned

Litter is a big issue in our local community. We must deal with it because it is bad for local wildlife and it makes our community look terrible.
This mostly occurs in our local park. It is caused by people dropping food wrappers from the nearby fast food restaurant.
So far, we make sure the park is cleaned every day. We have added more rubbish bins in the park to make it easier for people to dispose of this waste. We also spoke to the fast food restaurant and asked them to encourage people to dispose of their waste properly.
There is a plan to add more bins and signs to inform people about the need to dispose of waste properly. We have also asked the restaurant to provide help in cleaning up their waste.
The issue has been dealt with well, but more work is needed. It is hard to deal with these issues because there is never-ending source of waste as people will always need to buy food. In the future, the best solution would be to find alternative ways of packaging.
