Topic: Environmental Awareness Post Covid-19 & Strategies for Sustainability The global outbreak of coronavirus disease 2019 (COVID-19) is affecting every part of human lives, including the physical world. The measures taken to control the spread of the virus and the slowdown of economic activities have significant effects on the environment. The pandemic situation significantly improves air quality in different cities across the world, reduces GHGS emission, lessens water pollution and noise, and reduces the pressure on the tourist destinations, which may assist with the restoration of the ecological system In addition, there are also some negative consequences of COVID-19, such as increase of medical waste, haphazard use and disposal of disinfectants, mask, and gloves; and burden of untreated wastes continuously endangering the environment. It seems that, economic activities will return soon after the pandemic and the situation might change- t According to the secretary-general of Environment and Water Ministry Malaysia, Dr Zaini Umang. One of the most predominantly reported positive impacts of Covid-19 on the environment is the sizeable improvement in air quality, reduced greenhouse gases (GHG) emission, reduced water pollution and less pressure on tourist destinations. Intuitively, these are the correlational and causal effects of the lockdown imposition, which forcibly and temporarily shut off economic and social activities. It is reported that by April last year, 3.9 billion people in more than 90 countries, including Malaysia. had been ordered to stay indoors for weeks. When half of the world population was in lockdown. mobility was drastically reduced by up to 90 per cent. As a result, environmental pollution sharply scaled down to 30 per cent. Also by April last year, the daily global carbon dioxide emission decreased by 11 to 25 per cent with respect to the mean level of emissions in 2019. In Malaysia, Air Pollutant Index (API) analysis conducted between March 1 and April 28 last year showed a 26 per cent increase in API for the number of "clean" days since the Movement Control Order (MCO) came into force. It also found that the PM2.5 concentrations showed a high reduction of up to 58.4 per cent during the MCO.- Another positive impact of the pandemic is the heightened appreciation for the nature. Compellingly, when people are compounded by the isolation of lockdowns, mobility patterns are somehow altered, resulting in a widespread engagement with green and blue spaces (parks. forests, lakes and rivers). This is especially true for city dwellers living in densely settled areas. where these spaces are not a luxury. More people are also looking to outdoor recreation. gardening and urban farming. All these highlight the value of nature for physical and mental health, as well as the importance of environmental stewardship. However, when the MCO was gradually lifted and the economy reopened, post-lockdown pollution resurfaced. The pandemic only resembled an added variable to the environmental quality but, in reality, pollution and pollutants remain anthropogenic. For instance, the monitoring of river water quality shows a significant increase in the average daily concentration of total suspended solids (TSS) when the first round of MCO was lifted and replaced with the Conditional Movement Control Order. This indicates that activities involving earthwork, whether for
