Coronavirus Disease (COVID-19) has become the largest pandemic that has affected 210 countries. Rolling data indicate that 257,3605 people are infected by the disease, from which 701,838 have recovered and 178,562 have died. No specific medicine or vaccine is available yet to control the disease, hence, social distancing via lockdown is widely adopted as the only preventive measure. Social distancing is observed at different level of strictness in different counties but it almost made the world to stands still. Although scientific articles on this largest social move are scanty, it resulted in benefiting the deteriorated environment to revive back. Many environmental indices such as lowering NO and CO emissions and reduction in particulate matters in air as a result of less human activities have led to clean air and pollution free water in many countries. Undoubtedly, the world was experiencing pollution in several countries due to mainly human activities including urbanization, industrialization, fossil fuel exhaustion etc. Under such situation a special (natural) a protective measure was awaited to fix environmental issues. Probably, the lockdown is one of the natural effects expected by nature via introduction of COVID-19. It is because, introduction of COVID-19 to nature was an outcome of mutation from two of its pre-existing forms, although, debate on it is still continuing. Viability of CoV-19 virus found to have a lot of correlation with aquatic and terrestrial environmental parameters such as pH, surface type, temperature etc. Air pollution is found to increase the risk of COVID-19 infection, therefore, use of mask and alcohols based standard sterilisers is strongly recommended. However, the self-revival rate of nature shall continue during post-lockdown period and a master plan must be adapted by national and international (mostly political) bodies to revive the Mother Nature completely.
新型冠状病毒病（COVID-19）已成为影响 210 个国家的最大规模大流行疾病。滚动数据显示，全球有 2573605 人感染了该病毒，其中 701838 人已经康复，178562 人死亡。目前尚无控制该疾病的特效药或疫苗，因此，广泛采用社交隔离的封城措施作为唯一的预防措施。不同国家的社交隔离措施严格程度不同，但这几乎使世界陷入停顿。尽管关于这一最大规模社会活动的科学文章很少，但它确实使恶化的环境得到了恢复。由于人类活动减少，许多环境指标如氮氧化物和一氧化碳排放量的降低以及空气中颗粒物的减少，导致许多国家的空气变得清新，水变得无污染。毫无疑问，由于人类活动包括城市化、工业化、化石燃料枯竭等，世界上有几个国家正在经历污染。在这种情况下，人们期待一种特殊的（自然的）保护措施来解决环境问题。也许，封城是大自然通过引入 COVID-19 而采取的一种自然保护措施。这是因为，COVID-19 引入自然界是其两种先前存在形式突变的结果，尽管对此仍存在争议。研究发现，CoV-19 病毒的存活能力与水和陆地环境参数如 pH 值、表面类型、温度等有很大的相关性。空气污染被发现会增加 COVID-19 感染的风险，因此，强烈建议使用口罩和含酒精的标准消毒剂。然而，在封城解除后，大自然的自我恢复能力将继续，国家和国际（主要是政治）机构必须制定一个总体规划，以完全恢复大自然。
