essay on effect on environment due to covid 19
Answers
Answer:
The worldwide disruption caused by the COVID-19 pandemic has resulted in numerous impacts on the environment and the climate. The considerable decline in planned travel[2] has caused many regions to experience a large drop in air pollution. In China, lockdowns and other measures resulted in a 25 per cent reduction in carbon emissions[3] and 50 per cent reduction in nitrogen oxides emissions,[4] which one Earth systems scientist estimated may have saved at least 77,000 lives over two months.[5][6] 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.[7][8][9][10][11]
However, the outbreak has also provided cover for illegal activities such as deforestation of the Amazon rainforest[12][13] and poaching in Africa,[14][15] hindered environmental diplomacy efforts,[16] and created economic fallout that some predict will slow investment in green energy technologies.[17

Explanation:
Due to the coronavirus outbreak's impact on travel and industry, many regions and the planet as a whole experienced a drop in air pollution.Reducing air pollution can reduce both climate change and COVID-19 risks but it is not yet clear which types of air pollution (if any) are common risks to both climate change and COVID-19. The Centre for Research on Energy and Clean Air reported that methods to contain the spread of coronavirus, such as quarantines and travel bans, resulted in a 25 per cent reduction of carbon emission in China.In the first month of lockdowns, China produced approximately 200 million fewer metric tons of carbon dioxide than the same period in 2019, due to the reduction in air traffic, oil refining, and coal consumption.One Earth systems scientist estimated that this reduction may have saved at least 77,000 lives. However, Sarah Ladislaw from the Center for Strategic & International Studies argued that reductions in emissions due to economic downturns should not be seen as beneficial, stating that China's attempts to return to previous rates of growth amidst trade wars and supply chain disruptions in the energy market will worsen its environmental impact. Between 1 January and 11 March 2020, the European Space Agency observed a marked decline in nitrous oxide emissions from cars, power plants, and factories in the Po Valley region in northern Italy, coinciding with lockdowns in the region.
the water in the canals cleared and experienced greater water flow and visibility of fish. the increase in water clarity was due to the settling of sediment that is disturbed by boat traffic and mentioned the decrease in air pollution along the waterways.
Demand for fish and fish prices have both decreased due to the pandemic,and fishing fleets around the world sit mostly idle.German scientist Rainer Froese has said the fish biomass will increase due to the sharp decline in fishing, and projected that in European waters, some fish such as herring could double their biomass. As of April 2020, signs of aquatic recovery remain mostly anecdotal.
As people stayed at home due to lockdown and travel restrictions, some animals have been spotted in cities. Sea turtles were spotted laying eggs on beaches they once avoided (such as the coast of the Bay of Bengal), due to the lowered levels of human interference and light pollution.
Conservationists expect that African countries will experience a massive surge in bush meat poaching. Matt Brown of the Nature Conservancy said that "When people don't have any other alternative for income, our prediction -- and we're seeing this in South Africa -- is that poaching will go up for high-value products like rhino horn and ivory."On the other hand, Gabon decided to ban the human consumption of bats and pangolins, to stem the spread of zoonotic diseases, as the novel coronavirus is thought to have transmitted itself to humans through these animals.
