An Overview-Effects of Covid 19 Pandemic on Climate Change in India

From a public health perspective, the spread of the COVID-19 virus has become a problem. The incredible rise in disease-related infection and death rates has brought the world to a standstill in dealing with its negative consequences. This has led to a global lockdown to prevent further spread of the virus. The blockade had a huge social and economic impact. However, it also has some positive effects on the environment, especially air quality, as many research institutes point to reduced nitrogen dioxide and carbon monoxide problems in major cities (PM) around the world. Ni#trogen dioxide emissions were reduced by 20-30% in China, Italy, France and Spain, while nitrogen dioxide emissions were reduced by 30% in the United States. Compared to last year, China's air quality improved by 11.4%. NO (-77.3%), NO2 (-54.3). Compared to five years per month, 3% and carbon monoxide (-64.8%) (Signs point to a decrease) content were found during Partial shutdown in Brazil. There are about -51.84, -53.11, -17 in India 97%, -52.68, -30.35, 0.78, and -12.33 reductions in PM10, PM2 concentrations. They are SO2, NO2, CO, O3 and NH3. This article focuses on the environmental impact of closures and also discusses air pollution before and after closures in major cities around the world. Various aspects of the environment were studied and evaluated, including air, water, noise and waste management before and after closure. Therefore, this research will serve as a guide for environmentalists, leaders, and frontline activists as they look for ways to beat this disease and reduce its long-term impact on health and the environment.
