Assignment:
Will Covid-19 have a lasting impact on the environment? (Based on the news reported by the BBC, 27th March 2020) Pollution and greenhouse gas emissions have fallen across continents as countries try to contain the spread of the new coronavirus. Is this just a fleeting change, or could it lead to longer-lasting falls in emissions?
In a matter of months, the world has been transformed. Thousands of people have already died, and hundreds of thousands more have fallen ill, from a coronavirus that was previously unknown before appearing in the city of Wuhan in December 2019. For millions of others who have not caught the disease, their entire way of life has changed by it.
SAMPLE FINAL ASSESSMENT
The streets of Wuhan, China, were deserted after authorities implemented a strict lockdown. In Italy, the most extensive travel restrictions were in place since World War Two. In London, the normally bustling pubs, bars and theatres have been closed and people have been told to stay in their homes. Worldwide, flights are being cancelled or turning around in mid-air, as the aviation industry buckles. Those who are able to do so are holed up at home, practicing social distancing and working remotely.
It is all aimed at controlling the spread of Covid-19, and hopefully reducing the death toll. But all this change has also led to some unexpected consequences. As industries, transport networks and businesses have closed down; it has brought a sudden drop in carbon emissions. Compared with this time last year, levels of pollution in New York have reduced by nearly 50% because of measures to contain the virus.
In China, emissions fell 25% at the start of the year as people were instructed to stay at home, factories shuttered and coal use fell by 40% at China's six largest power plants since the last quarter of 2019. The proportion of days with good quality air was up 11.4% compared with the same time last year in 337 cities across China, according to its Ministry of Ecology and Environment. In Europe, satellite images show nitrogen dioxide (NO2) emissions fading away over northem Italy. A similar story is playing out in Spain and the UK.
Only an immediate and existential threat like Covid-19 could have led to such a profound change so fast; at the time of writing, global deaths from the virus had passed 20,000, with more than 400,000 cases confirmed worldwide. As well as the toll of early deaths, the pandemic has brought widespread job losses and threatened the livelihoods of millions as businesses struggle to cope with the restrictions being put in place to control the virus. Economic activity has stalled and stock markets have tumbled alongside the falling carbon emissions. It's the precisely opposite of the drive towards a decarbonised, sustainable economy that many have been advocating for decades.
A global pandemic that is claiming people's lives certainly should not be seen as a way of bringing about environmental change either. For one thing, it's far from certain how lasting this dip in emissions will be. When the pandemic eventually subsides, will carbon and pollutant emissions "bounce back so much that it will be as if this clear-skied interlude never happened? Or could the changes we see today have a more persistent effect?
Answer the following question:
Using the theories and concepts from this unit, how can govemments, businesses, society and NGOs continue to leverage on the positive environmental impact that has been observed during the Covid19 lockdowns?
