What problems are easy to encounter with disposable paper cups?

Disposable paper cups are widely used, but there are also some problems. First of all, the production of disposable paper cups consumes a lot of wood and energy resources, which has a certain impact on the environment. Secondly, since disposable paper cups are usually coated with plastic to prevent water leakage, it is difficult to decompose the paper cups, resulting in environmental pollution. In addition, disposable paper cups are often discarded at will after use, which increases the burden of garbage disposal and causes waste accumulation and pollution. In addition, since paper cups are usually not resistant to high temperatures, it may cause deformation and leakage of the cup when using hot drinks, causing inconvenience to users. Finally, there is a risk of burns during the use of disposable paper cups, because the outer wall of the paper cup conducts heat faster, and users need to be careful when using it. Therefore, in order to reduce the environmental burden and avoid the above problems, the reduction of the use of disposable paper cups should be encouraged and the use of reusable cups should be advocated.
