绿色发展：让自然美景永驻人间

材料一：2016年3月10日，中共中央******在参加十二届全国人大四次会议青海代表团审议时强调，一定要生态保护优先，要像保护眼睛一样保护生态环境，像对待生命一样对待生态环境。发展必须是遵循经济规律的科学发展，必须是遵循自然规律的可持续发展，必须是遵循社会规律的包容性发展。尊重自然、顺应自然、保护自然，才是可持续发展的必然选择。所以，必须实施“碧水蓝天”工程，坚持在发展中保护、在保护中发展。

材料二：改革开放以来，中国经济在全球经济版图中一枝独秀，呈现出前所未有的快速繁荣景象，一次又一次在世界面前刷新着高增速的“中国奇迹”，也让人民群众普遍富裕起来，但随之而来的则是：马路宽了，高楼多了，钱包鼓了，可是清澈的河水、洁净的空气却成了奢侈品。粗放的发展方式，让我们在资源环境方面付出沉重代价，在得到“金山银山”的同时，我们的“绿水青山”正逐渐消逝在我们的视野中。
