不知何时起,口罩的设计似乎越来越好了,从一些路人戴的那种又小又尖的、像防毒面具一般的口罩到前阵新闻里说的给交警佩戴的隐形口罩,技术含量明显提高了。然而,现在走在大街上,竟不怎么敢大口呼吸了。首都连日的阴霾和黄沙,使很多人选择待在屋里,同时还要装一个空气净化器才能放心呼吸,这是怎么了?城镇建设的推进势必造成对环境的影响,虽然是这样,城市化也是一个必然的过程。如果是无知,之前造成的破坏现在已经开始呈现结果了。那么,接下来的建设又该如何避免破坏,或者说随时反省和弥补,这是一个时代的课题,而问题已然摆在面前,势不容缓。 I do not know when, masks design seems better and better, from the kind of passers wearing the kind of small and sharp, masks like gas masks to the front news that invisible masks worn by traffic police, technical content Significantly improved. However, now walking in the street, did not dare to breathe. The haze and yellow sand in the capital for a long time have caused many people to choose to stay in their homes and have to install an air purifier to breathe safely. What is going on? The promotion of urban construction is bound to have an impact on the environment. Although this is true, Is also an inevitable process. If it is ignorance, the damage that was done before is now starting to show up. Then, what should be done to avoid any further damage in the future, or to reflect on and make corrections at any time? This is an issue of the times.
