Less use of transport reduced air pollution
Reduction in industrial activities reduced land pollution and water pollution
Carbon emission was reduced due to less fossil fuel burning
Deforestation activities were stopped during lockdown etc.
5.2. Negative Impacts
COVID-19 has many negative impacts on environment as given below:
Increased death rate
Disturbed food chain
Public health was badly affected
Loss in biodiversity etc.
