In our daily lives, we often see people spitting on the ground in public places. This bad habit not only affects the environment but also brings many health risks to others. As a university student, I believe it is our responsibility to raise awareness about this issue and take action to change this behavior.

First of all, spitting on the ground is a serious violation of public hygiene. It can spread germs and diseases easily, especially in crowded areas like schools, parks, and transportation stations. Many diseases, such as tuberculosis and colds, can be transmitted through saliva. Therefore, if people continue to spit anywhere, they are not only harming themselves but also endangering the health of others.

Secondly, this behavior reflects a lack of social responsibility and respect for others. In modern society, people are expected to behave politely and follow rules. Spitting on the ground shows a lack of consideration for public spaces and the feelings of those around us. It is a sign of low cultural quality and poor manners.

Moreover, many cities have already taken measures to deal with this problem. For example, some places have put up signs that remind people not to spit. Others have even imposed fines on those who violate the rules. These actions are necessary, but they are not enough. What we need most is a change in people's attitudes and habits.

As students, we should set an example by not spitting anywhere. We can also help educate others about the negative effects of this behavior. By doing so, we can contribute to building a cleaner and healthier environment for everyone.

In conclusion, spitting on the ground is not just a small matter. It has a great impact on public health and social order. We should all take it seriously and do our part to stop this bad habit. Only by working together can we create a better living environment for ourselves and future generations.
