## **Abstract**

In just a few months, COVID-19 transformed from a dangerous regional health threat into a widespread global pandemic and economic disaster. Thus the world is expecting a great recession once again. The rapid spread of COVID-19 has had far-reaching consequences for people's daily lives in almost all parts of the world. Climate change and biodiversity depletion have now reached global boundaries; thus, human activity has surpassed Earth's capacities. Earth capacities can be explained in terms of extreme climate change. This chapter is intended to investigate the link between the outbreak of Covid-19 and its effect on environmental and society. The discussion reveals that environmental pollution is minimized as a result of global lockdown. Furthermore, our review also shows that in terms of environment, Covid-19 provide an opportunity to transform our polluted economy toward the green economy through adoption of renewable energy sources and green practices in our businesses.

### **1. Introduction**

The estimated age of this world is approximate (13.8 billion years). In all these years, there are some incidences experienced by a human, which reshaped the entire behavior of human. World war I, II, cold war era and more recently the incident of 9/II all these incidences in world history suddenly changed the power centers, the world moved from unipolar to bipolar or even toward multipolar world order. Furthermore, all these event or incidence dramatically changed the over economic systems, way of governing nations and even changed our literature as well. Even all these incidences changed the lifestyle of the entire world, similarly, the ongoing pandemic crises of covid-19 will have a permanent and everlasting impact on our lives [1, 2].

It is generally believe that once pandemic crises will over; the world will be not the same as it was before. Technically, due to hyper-growth, presence of high tech inventions, innovation and more especially the extensive use to the internet already made this world liquidness thus we are unable to identify where it will be stopped or freeze. On the other hand, nowadays, this pandemic situation just created the new standard among us; it is also true; thus, it locked down the entire world in one corner. At the

moment, due to this pandemic, the circle of growth has become stiff. Thousands of airlines are not functioning, and the majority of the tourist places are closed, furthermore there not any educational activities are going on in most effected countries of covid-19. Similarly; on the other hand, this world not facing the pandemic situation the first time. History reveals that there were numerous pandemic crises experienced by this world. Due to all these pandemic crises, millions of people lost their lives. **Table 1**, indicates major pandemic crises experienced by the world in history.

In the recent era, especially at the beginning of the 21st century, two more pre-mature pandemic crises hit numerous countries of the world. Avian influenza, which is known as bird flow virus, infected hundreds of people from 2003 to 2011 in almost 60 countries of the world. According to the World Health Organization estimation, more than 1500 people died due to this influenza. Furthermore, in 2009 swine flu (H1N1) spread over more than 100 countries of the world, and approximately 550,000 people lost their lives due to this (Centers for Disease Control and Preventions). On the other hand, from 2013 to 2016, the Ebola virus hit western African countries, and more than 11,000 people died. Similarly, there are numerous diseases which cause millions of death worldwide every year. Due to HIV (AIDS) 32 million people died, whereas due to malaria, just in 2018, approximately 400,000 people died (World Health Organization).

#### **2. Climate change: why it matter?**

Before discussing actual environmental issues, it essential to describe the phenomenon of climate change. United Nations Framework Convention on Climate Change defines it as "a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable periods" [3]. Similarly, on the other hand, Rahman, [4] define it as 'our climate is changing, largely due to the observed increases in human-produced greenhouse gases. Greenhouse gases absorb heat from the sun in the atmosphere and reduce the amount of heat escaping into space. This extra heat is the primary cause of observed changes in the climate system over the 20th century. However one question arises

The most noticeable effects of overshooting or overutilization of natural resources can be observed through diminishing forest covers, collapsing fisheries, rapid fall in water level under the earth crust, carbon dioxide emissions which all are creating global climate change.

surrounds us. Similarly, one of the most destructive effects of all these harmful gases in our environment and atmosphere is depletion of the ozone layer which protect humans and surface of the earth from the adverse impact of sun rays. The concentration of harmful gases in the atmosphere increases the average temperature of the world, which negatively affect the glaciers and phenomenon of melting ice increases very rapidly. Melting of ice in summer season induces floods in our river, which causes loss of human life and another material loses as well. However, massive waves in the sea and similarly melting ice slabs directly increase sea level, which influences the life of people living on the seashores. The **Figure 1** indicates the average increase in world temperature recorded in the last 40 year. Thus we can see that average temperature indicating an upward trend, which is an indeed alarming situation for everyone.

The world-renowned, global climate change activist, Greta Thunberg Said, "And Yes I know that we need a system change rather than individual change, but you cannot have one without the other. If we explore the history, all the big changes in society have been started by the people at the grassroots level. No system change can come without pressure from the large group of individual'. Thus, it is right the entire world needs collective efforts to face all the challenges to arise by climate change. Moreover, the highest responsibility is on the shoulder of the business community, policy markers, world leaders and politicians. The business community employs by using the labor from the factor of production; moreover, they also put capital along with the utilization of land resources which are also the factor of production. However, unsustainable utilization of land resources creates massive climate change threats. Every year tons of plastic waste is buried without recycling under the surface of the earth and dump in oceans as well.

Similarly, in order to fight against hunger and our food necessities, our farmer's working day and night on land resources and grow crops and planted fruits trees. However, by using heavy pesticides and fertilizer we can double the quantity of wheat in less time but on the other hand, one of the significant adverse effects of pesticides are the death of eco-friendly insects. Similarly, extensive use of fertilizer is finishing the natural tendency of soil to grow crops.

global matter, therefore; requires worldwide attention and contribution.

Similarly, as **Figure 2** indicates the sunlight rays pass through the ozone layer, which eventually increases the temperature. Achieving sustainability requires collective action by the entire stakeholder of society; in fact, it requires action from the farmer working in the farm and earning for his family as well as a high corporate executive. One of the significant issues now a day's faced by our society is income inequalities or unequal distribution of wealth, which divide our societies into different classes. One of the most destructive factors which arise in our society is that the rich become richer and the poor become poorer. Similarly, income inequalities can be observed in developed countries and as well as in developing countries. In developing countries usually, rich people have access toward the higher political level. One of the most challenging situations can be observed in developing countries in which wealthy class, provide access to the foreigner investor in their country and due to weak local legal system and absence of environmental laws and regulations, heavily polluting industries is formed in host countries which adversely affect the

Every next coming day increases the world population in such manner that, every consecutive day noted as the highest population ever recorded in the world. Similarly, our rural areas are finishing very rapidly. On the other hand, urban concentration is increasing, which cause a heavy abnormal burden on cities. One of the most major adverse effects can be observed in developing countries and more specifically in unplanned cities as the majority of unplanned cities in the world are expanding in such manner that majority of the people living there without basic human needs such as access of freshwater, sewerage system and some of the places even with the access of electricity. The UN Framework Convention on Climate Change [8] in their report predicted that billions of people in developing countries would face shortages of water, food and more significant risks to health. Thus it requires immediate action in a sustainable way along with effective planning and then assessments. The issue which arises due to climate change will not be solved suddenly; in fact, it is a long term process which requires proper planning and contribution of every stakeholder and individual. As we already discussed earlier, it is not an issue of one individual, single community or a country's problem. Thus its

atmosphere. However, recently it had also been noticed that polluted industries also induce health issue for the local communities, including lungs cancer and asthma. The more adverse effect can be observed in developing countries in the shape of massive life losses where medical facilities are not so much advance and widely available. Apparently, in such situation, it is the responsibility of all the stakeholders to identity such industries which create an environmental hazard as well as, higher leadership should also take strict action to fight against global warming issues [10]. On the other hand, it has also been observed that in developing countries the industrial waste is directly dumped into the rivers and sea without any further recycling [11]. Therefore life undersea and river profoundly affected as well. Similarly, the extensive use of plastics also harms our surroundings.

## **3. Nexus between Covid-19 and environment**

Air pollution is one of the most considerable catalyst factors which is harming our environment. Air Pollution defined as release of poisonous gases, which are emitted by factories and transportation. As due to the pandemic crises, from beginning of the year most of the countries of the world were in lockdown situation. Due to the fact, lock down situation ultimately affects every sector of the world. The overall world output dramatically decreased due to the lockdown and millions of the people lost their jobs. **Figure 3**, indicate impact of Covid-19 on different economic activities around the world.

Similarly an empirical study conducted by Barro et al. [12] reveal due pandemic crises on average 2.1% death rate could cause decline of averagely 6% of world GDP and 8% decline in private consumption. Furthermore, in terms of macroeconomic impact, Coibion et al. [13] empirically analysis pandemic impact using survey on household in the US. They conclude that, due to pandemic crises consumption and employment decreased where as inflation and economic uncertainty increased.

It is true to argue that, due to the massive lockdown in the world overall production and consumption decreased. Lockdown indicate downward trend of industrial output and due to 'stay safe stay health' less transportation vehicles were used by people which directly impact on the overall air pollution of the world [14].

In terms of empirical studies, Brodeur et al. [15] mention in their work 'safer-athome' policies indicatively decreased air pollution across US counties. Therefore we can argue that one the key factor which contribute downward trend of air pollution is transportation vehicles thus consumption of gasoline as fuel. Similarly, Cicala et al. [16] identified in USA the average sales of gasoline from 2007 to 2019 average recorded as 8000 to 9000 barrels per day, however due to the lockdown and less mobility, the average sales drop at 5000 barrels per day until 12th week of 2020 (**Figure 4**).

On the hand, it is also true beside industrial sector and road transportation the large consumption sector of fuel is airline industry, although due the lockdown situation massive airlines of the world grounded there air craft's and international mobility stopped as well. Indeed, that particular factor also decreases overall air pollution.

It has be also observed that, air travel thus airline industry account for about 2.5% of global CO2 emission; furthermore it is predicted that until 2050 airline industry could take up a quarter of the world's carbon budget and it will cause for 1.5 degree Celsius world temperature [17]. **Figure 5**; indicate first quarter international flights and transportation activity around the world.

In terms of china, Almond et al. [19] investigate nexus between air pollution and gases emission during covid-19 crises. They conclude that during the crises NO2

emission decline whereas SO2 did not fall. Furthermore they also mention that, in overall China (PM2.5) emission decreased by 22%. The major cause of reduction in air pollution is due to less personal vehicle usage which is heavily responsible for NO2 emission. Similarly, in case of china another study conducted by He et al. [20] also concluded same results, due to the lockdown in china PM2.5 concentration decline by 25%. That particular phenomenon were recorded in more industrialized cities, therefore it is true to argue that the fall in industrial production is positively associated with reduction in air pollution. One more study conducted by Yao et al. [21], mention that higher humidity causing spread of the Covid-19, and they further illustrate that high level of NO2 emission, playing role as catalyst agent and

Similarly not only European countries have to experience clean air, on the other hand, a country like India, which is the second-highest populated country of the world, due to the lockdown situation the trend of air pollution also declined in India [23]. It is also true that, due to lockdown in massive countries of the world, the overall pollution decreases rapidly; thus, environment restores as it was 50 year ago. Not only, lockdown reduce air pollution; eventually, it also impacts on water pollution. In Europe, the death toll of covid-19 record massively high in Italy, therefore during the lockdown in Italy tourist arrival become zero almost, which impact on water quality in the canals of Venice. After couples of decades, the resident of Venice city has noticed clean water and marine life in the channels again [2]. The significant declines which has also been observed in the pattern of the overall consumption of electricity. As many of the people working from home, this directly decreases electricity consumption. Furthermore, the countries which heavily depend on electricity production via coal have experienced a decline in CO2 emission as well. It is right to argue that covid-19 ultimately reduced the consumption of electricity and fuel consumption for producing electricity as well [24]. Below **Figure 7** indicate, the overall pattern of NO2 emission in Europe during 2019

The positive change and transformation in environment is generally due to the lockdown situation in terms of clean air and clean water channels, will not be

Similarly not only European countries have to experience clean air, on the other hand, a country like India, which is the second-highest populated country of the world, due to the lockdown situation the trend of air pollution also declined in India [23]. It is also true that, due to lockdown in massive countries of the world, the overall pollution decreases rapidly; thus, environment restores as it was 50 year ago. Not only, lockdown reduce air pollution; eventually, it also impacts on water pollution. In Europe, the death toll of covid-19 record massively high in Italy, therefore during the lockdown in Italy tourist arrival become zero almost, which impact on water quality in the canals of Venice. After couples of decades, the resident of Venice city has noticed clean water and marine life in the channels again [2]. The significant declines which has also been observed in the pattern of the overall consumption of electricity. As many of the people working from home, this directly decreases electricity consumption. Furthermore, the countries which heavily depend on electricity production via coal have experienced a decline in CO2 emission as well. It is right to argue that covid-19 ultimately reduced the consumption of electricity and fuel consumption for producing electricity as well [24]. Below **Figure 7** indicate, the overall pattern of NO2 emission in Europe during 2019 and 2020, thus after the lockdown situation.

long-lasting and it is expected that our environment once again will harm as the world will experience normal cycle of life; thus we will again experience massive air and other pollution [26]. Massive corporate allow remote work for their employees. Remote work will enable people less mobility, thus, which decrease the usability of the vehicle. However at the moment it is not responsibility of single person or a country to maintain that transformation, thus we should promote a green ideology, which will ultimately reduce air pollution and on the other hand green concept will improve countries' social, economic and environmental performance. Furthermore, we should also focus on renewable energy in overall logistics operations, as it ultimately improves environmental performance by reducing emission whereas environmental performance is negatively correlated with public health expenditure as explained in literature [27].
