Hello everyone. Today, our group wants to talk about a serious problem in our area: Water Pollution. As you can see on our poster, the river near our school is very dirty. People throw plastic bags, bottles, and rubbish into it. This makes the water black and smelly. It kills many fish and is dangerous for our health. To solve this problem, we suggest some solutions: First, we should stop littering into the water. Second, we can organize a clean-up day every month to pick up rubbish along the river. Finally, we should reduce using single-use plastic products. Let’s protect our water to save our lives. Thank you for listening!

Lựa chọn 2: Air Pollution

Hi guys. Look at the grey sky in our poster. That is Air Pollution, and it is happening right here in our city. There are too many motorbikes and cars on the road. They release harmful smoke into the air. Also, smoke from factories makes it hard to breathe. This causes many health problems for us. So, what should we do? Our group thinks we should use public transport like buses instead of private cars. We can also cycle or walk to school if it's near. Moreover, planting more trees is a great way to clean the air. Let's go green to breathe clean air! Does anyone have any questions for us?
