Answers
The worldwide disruption caused by the COVID-19 pandemic has resulted in numerous impacts on the environment and the climate. The global reduction in modern human activity such as the considerable decline in planned travel[2] was coined anthropause[3] and has caused many regions to experience a large drop in air pollution.[4] In China, lockdowns and other measures resulted in a 25 per cent reduction in carbon emissions[5] and 50 per cent reduction in nitrogen oxides emissions,[6] which one Earth systems scientist estimated may have saved at least 77,000 lives over two months. Other positive impacts on the environment include governance-system-controlled investments towards a sustainable energy transition and other goals related to environmental protection such as the European Union's seven-year €1 trillion budget proposal and €750 billion recovery plan "Next Generation EU" which seeks to reserve 25% of EU spending for climate-friendly expenditure
Answer:
Decreased concentration of NO2 and PM 2.5
Air quality is essential for people's health; however, 91% of the world population lives in places where poor air quality exceeds the permissible limits (WHO, 2016). The consequences of air quality degradation are manifested in a significant percentage of global mortality each year (Zhang et al., 2017). In this regard, the 2016 World Health Organization (WHO) report indicates that air pollution contributes to almost 8% of total deaths in the world; the most affected countries being those found in Africa, Asia and part of Europe (WHO, 2016).
Clean Beaches
The lack of tourists, as a result of the social distancing measures due to the new coronavirus pandemic, has caused a notable change in the appearance of many beaches in the world. For example, beaches like those of Acapulco (Mexico), Barcelona (Spain), or Salinas (Ecuador) now look cleaner and with crystal clear waters.
Other Indirect Effects on Environment
China has asked wastewater treatment plants to strengthen their disinfection routines (mainly through increased use of chlorine) to prevent the new coronavirus from spreading through the wastewater. However, there is no evidence on the survival of the SARS-CoV2 virus in drinking water or wastewater (WHO, 2020b). On the contrary, the excess of chlorine in the water could generate harmful effects on people's health
