Venice clearer water
In link of lockdown due to covid19 that reduce the movement of Venice’s boats including the 'vaporetti' or water buses, as well as cruise ships (reduction of human activity), these two photos ESA one took On April 2020 and the other on April 2019.
​
This shows how water quality is affected by the limitation of human activities as The Italian government imposed a nationwide lockdown on the 9th of March 2020.
​
The water now looks clearer because there is less traffic on the canals, allowing the sediment to stay at the bottom.

Less fires in US
One of the consequences of COVID 19 wide spreading is the decline in Fire in the U.S. Southeast. prescribed burning programs have been disrupted by public health measures aimed at slowing the spread of the virus and minimizing smoke exposure. The U.S. Forest Service temporarily suspended all of its prescribed burns on federal lands in the Southeast in March, and state agencies in Mississippi, South Carolina, and North Carolina also issued spring burning bans. the number of active fires detected in the Southeast by the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite fell 42 percent below normal between January 1, 2020, and May 9, 2020.
So we can link the impact of covid19 that decrease the human activity as shown in this example the activity is prescribed burning program, and this reduction affects the environment in many ways, as it can be good impact as it decreases the greenhouse gases (carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and It has a bad impact as this fire was important to minimize wildfire risk, dispose of leftover wood after timber harvests, maintain plant and animal biodiversity, and improve wild game habitat, so after reduction the fires the wild game habitat won't be improved in addition of plant and animal biodiversity won't be maintained that will affect land life greatly.
