Make a g.o. using coloured sheets to show the positive impact of covid - 19 on water bodies and aquatic life.
Answers
Answer:
Water bodies, natural and built environment, and related sociological systems such as policy and governance, have experienced significant impact from the economic slowdown resulting from the Covid-19 pandemic. While human health and life are our primary and immediate concerns to address, water and environmental systems from local to regional scales have seen discernible positive impacts due to the reduction of pollutant loading from industries, vehicle emission, and other sources. Anecdotal evidence indicates reduction in biochemical oxygen demand and coliform levels in rivers, improvement in air quality as a result of reduction in the loading of nitrous oxide, particulate matter, and other pollutants. The extent of recovery seen would not have been possible without extreme measures that have been forced on the society due to the pandemic, at the cost of several trillions of dollars across the globe. This enormous unintended experiment offers opportunities for unprecedented insights about the dynamics of our natural and built environment, and societal systems that can lead to feasible paths for preservation of recovered systems and new recovery pathways through sensible policies and practices
