In recent years, with the rapid development of industry and urbanization, environmental pollution has become increasingly serious. Air quality deteriorates; water resources are contaminated; forests disappear at an alarming rate… All these phenomena indicate that we must take immediate action to protect our living environment before it is too late.

With the advancement of technology, online learning has gained popularity among students worldwide. This mode of education offers several advantages, including flexibility in scheduling classes according to personal needs, access to vast amounts of information through various platforms, and cost-effectiveness compared to traditional classroom settings.
However, there are also drawbacks associated with online learning. One major issue is lack of face-to-face interaction which may lead to feelings of isolation among learners. Another problem lies in self-discipline requirements; without proper guidance from teachers, some students might struggle to stay motivated throughout their studies.
Therefore, while embracing the benefits brought by digital tools, educators need to find ways to mitigate potential challenges so as to ensure effective teaching and learning experiences both online and offline.
