Problem-Solving Report: Single-Use Plastic Waste Single-use plastic products are widely used in daily life and are often thrown into rubbish bins after only one use. As a result, large amounts of plastic waste end up in landfills, where they can take hundreds of years to decompose. This causes serious environmental problems, including soil pollution, harm to wildlife, and the waste of natural resources. There are several possible solutions to reduce this problem. First, people should be encouraged to replace single-use plastics with reusable alternatives such as cloth bags, metal bottles, and reusable food containers. Second, governments can introduce policies to limit plastic use, for example by banning plastic bags or charging fees for single-use plastic products. In addition, recycling systems should be improved so that plastic waste can be reused instead of being dumped in landfills. Public education campaigns are also important to raise awareness about the negative impacts of plastic waste. In conclusion, reducing single-use plastic waste requires the cooperation of individuals, businesses, and governments. By changing daily habits and supporting sustainable solutions, we can protect the environment and reduce the long-term damage caused by plastic pollution.

The line graph shows population trends in Viet Nam from 1960 to 2020. Overall, the rural population decreased steadily, while the urban population increased significantly over the same period. In 1960, most Vietnamese people lived in rural areas, accounting for about 85% of the population, whereas only 15% lived in cities. From 1960 to 1980, the proportion of rural residents fell slightly to around 81%, and it continued to decline to 80% in 1990. After that, the decrease became more noticeable, dropping to 70% in 2010 and 63% in 2020. By contrast, the urban population rose throughout the period. It increased from 15% in 1960 to 19% in 1980, reached 20% in 1990, and then grew more rapidly to 30% in 2010 and 37% in 2020.
