素养是指个体在数字环境中有效、负责任地使用技术的能力，包括批判性评估信息、保护个人隐私和创造数字内容。文章指出，通过数字素养教育，学生能识别社交媒体中的虚假信息、减少情绪波动，从而降低负面影响。例如，某中学开展的项目通过教授学生辨别网红营销手段，显著降低了冲动消费行为。2.支持方认为监控摄像头能有效预防犯罪（如盗窃、袭击），提升公共安全感，且成本低于事后追责。反对方担忧隐私侵犯、数据滥用和"寒蝉效应"（公民因害怕被拍而减少自由活动），并指出技术可能被滥用（如政治监控）。文章指出平衡点在于透明立法和限制使用场景。3.主要问题：焦虑症（因社交比较）、抑郁（因孤独感增强）、网络成瘾（无法控制使用时长）。文章引用研究显示，每日使用超过4小时的学生中，35%报告情绪低落，而使用少于2小时者仅15%。4.回声室效应指算法根据用户偏好推送同质信息，形成封闭认知圈。后果包括观点极化、社会撕裂，因个体仅接触强化自身信念的内容（如极端政治言论）。文章以美国社交媒体为例，指出极右翼和极左
