The COVID 19 global pandemic has affected all aspects of human life.  The virus has claimed hundreds of thousands of lives in the world over, not to mention millions of people already infected with the virus. As of 29th April 2020, the virus had claimed more than 218,000 lives across the globe, according to figures released by WHO (World Health Organization).

Worse still, COVID 19 has led to massive closure of industries, thus resulting in skyrocketing unemployment rates. In some areas, food prices are at their highest.  Amid the gloom, there are various environmental benefits of the Coronavirus. Some of the most conspicuous positive environmental benefits range from an increase in air, water, and soil quality to a favorable framework for environmental management.

1.      A significant reduction in air pollution

To combat the pandemic, governments across the planet have adopted public health measures such as lockdowns, quarantines, and stay-at-home orders. With huge populations forced to remain in their homes, factories closed, airlines closed, and road traffics reduced to their minimum, air pollution levels have dwindled significantly over hundreds of years.

Due to reduced air pollution, air quality has improved dramatically, especially in major world cities. The Chinese province of Hubei, where the virus outbreak started in late 2019, recorded the first case of reduced pollution. This reduction occurred after the Chinese government introduced a lockdown in the entire province.

With COVID 19, there are a handful of planes traveling on the sky. Moreover, there are fewer vehicles on the roads. These developments translate into less air pollution. With air pollution levels at their lowest, the world’s ozone layer isn’t vulnerable to environmental hazards of air pollution.

2.      A reduction in greenhouse emissions

COVID 19 has led to a reduction of green gas emissions, particularly in highly industrialized nations because of the slowdown of economic activities worldwide. Countries such as China have recorded their lowest levels of emissions in decades.

As governments order closure of schools, industries, and factories, all of which contribute to a sharp rise in emissions, global gas emissions have dropped by 5% according to environmental experts at Global Carbon Project (GCP).

While the decline in green gas emissions as a result of COVID 19 may be temporary, the world is witnessing a sharp reduction in emissions over the decades. Furthermore, green gas emissions will continue dropping throughout the pandemic.

3.      Cleaner waters

Whereas COVID 19 has dramatically reduced the number of tourists in various world’s leading beaches, the waters in the world’s seas, oceans, and rivers are now cleaner than they used to be. In Italy, the canal waters in Venice are so clean such that fish can be spotted easily. There are just a handful of ships traveling on major global seaways. Again, the volume of waste disposed  in the seas and oceans has plummeted significantly. This reduced waste means less water pollution.

With a reduction in water pollution, water is cleaner and safe for consumption. A decrease in water pollutions translates into fewer water pollutants. As such, marine life is under minimal threat from water pollution.  In India, for instance, sea turtles have started arriving at the country’s eastern coast to lay eggs after the government issued a nationwide lockdown that saw millions staying at home following the Coronavirus outbreak.

Environmental benefits of coronavirus

4.      Nations will quickly meet their climate goals under the Paris Climate Accord.

Pundits claim that most nations will be able to meet their climate goals in accordance to the 2015 Paris Climate Accord, courtesy of the COVID 19 pandemic. Sectors such as production and transportation have come to a halt after the Coronavirus outbreak.

Consequently, the virus is driving nations towards reducing their emissions as envisaged in various global climate agreements.  Simply put, the virus outbreak has forced countries to lower their emissions hence prompting them to meet their international climate change obligations.

5.      An overall decline in global energy consumption rates

As millions of people are under strict lockdowns/curfews throughout the world, energy consumption rates have fallen sharply in decades. Energy consumption contributes significantly to the annual global gas emissions.

Although domestic energy consumption has soared significantly after the virus outbreak, industrial energy consumption rates have dropped dramatically at the same time. Industrial energy consumption is responsible for over a third of gas emissions in the world.

With the overall decline in global energy consumption, the world will benefit from reduced emissions, albeit temporarily. This reprieve has changed the global environment outlook for the better.

6.      An overall positive effect on the global climate

The measures taken by governments to combat the spread of COVID 19 have a short term positive effect on the global environment.  With vast populations barred from leaving home and travel bans imposed on major airlines, the environmental consequences brought about by such restrictive measures will give the world the much-needed respite.

A global reduction in gas emissions and pollution will contribute positively to the global climate. The pandemic has reversed some of the adverse effects caused by the infamous climate change. Even after the pandemic is over, governments will have a clear picture of the measures they ought to put in place to address the suppression of the climate.

Overly, the pandemic has led to a massive scale-down of industrial production and energy use. These two have, for decades, been the most significant contributors to climate change. Without them, the global climate will change for the better. But to maintain these benefits in the long-run, governments will have to take planned approaches to eliminate unnecessary energy consumption and industrial production after the pandemic.

7.      Closure of wet Markets

The wet market of Wuhan is the suspected source of Coronavirus. As such, authorities have stopped the operations of various wet markets following the devastating impacts of the COVID 19. For many years, conservationists have pushed for the closure of such markets. One of the most significant environmental benefit of the coronavirus is realizing stopping wet markets is possible.

Conclusion

The Coronavirus pandemic may have brought misery to the world. While the deadly virus has visibly brought everything on the planet to a halt, the environment seems to be the biggest beneficiary of the pandemic. Nonetheless, these environmental benefits that have been brought about by COVID 19 may only be temporary. As such, nations should make changes that will retain these benefits even after the end of the pandemic.

Wildlife trade hotspots, issues, and methods are pertinent conservation issues. By definition, wildlife trade refers to a lucrative business that entails killing wild animals and selling products and parts derived from them. It has adverse effects on wildlife populations, local communities, and the environment at large. 

Although most nations have banned wildlife trade,  the illegal trade is still fueled by a market with a massive appetite for animal parts. As this article expounds, wildlife trade is still a common occurrence across the globe because the demand for it is widespread.

Where does wildlife trade occur?

The latest data released by the World Wildlife Fund (WWF) shows that wildlife trafficking takes place in almost 30% of the world’s wildlife-inhabited areas.  These areas include some of the most ecologically important places in the world. 

World heritage sites have also become an easy target for wildlife trade. These sites support vast populations of unique animal and plant species.  The illegal, multi-billion-dollar business is prevalent in Asia, where the continent houses over 3,890 tigers.

Africa has also become a haven for wildlife trading. After all, it has a large number of commonly traded species such as elephants, rhinos, crocodiles, big cats, pangolins, primates, and birds.  For instance,  illegal trading of ivory has become a typical vice in the continent. In oriental countries like China, there is a belief that rhino horns are a cure for a variety of ailments. This belief has led to an increased rhino poaching in Africa. The trade of wildlife trade is also local within the continent. Markets for bushmeats are ubiquitous in West Africa, while trade in antelopes occurs illegally in East and South Africa.

Pangolins are the most trafficked animals in the world. Like the case with rhinos, some people believe that their scales have remarkable medicinal values.

While wildlife trade is rampant globally, they are some well-known wildlife trade hotspots. These hotspots include Chinese international borders. China is a leading market for illegal wildlife trade because most of its vast population have weird superstition on wildlife. There are also wildlife trade hubs in Southern Asia and Southern/ Eastern Africa. Other hotspots include the EU’s eastern borders, Mexico, and some Caribbean nations. In recent years, countries such as Ivory Coast (Côte d’Ivoire) have also emerged as hotspots for illegal wildlife trade.

How trade of wildlife happens

It is virtually impossible to list all the ways that wildlife trade occurs because they are so many, and illegal wildlife traffickers would often change the styles. However, most of the business of wildlife has at least one of these elements.

  1. Legal means as perpetrators attempt to follow the rules. However, in most cases, legal means only involves paperwork. Many countries in the world cannot assess the source and quantity of wildlife traded.
  2. Even in the cases where wildlife is legally traded, a scrutiny of the supply chain often shows some illegality along the way. For instance, traders can steal wildlife and present it as legally obtained.
  3. Wet markets offer a trading haven for wildlife trade. Wet markets provide a marketplace for selling live wildlife and other products.  Wet markets are common throughout Asia.  In these markets, throngs of customers come to shop for live animals. Poachers supply wet markets with live animals and their parts. Wet markets occur in Africa, as well. Like the first two points, wet markets may be legal, but the sourcing of the wildlife may have questionable supply chains.

Generally, most wildlife trade is illegal and involves organized gangs. The illegal trade takes place in nations where there is a huge demand for animal parts. The vice is rife in almost every region with an abundant number of endangered species such as elephants, tigers, rhinos, and other marine animals.

Why is wildlife trade occurring?

The entire globe faces the plight of wildlife trade.  Even in nations that have enacted strict poaching laws and punishments, the illegal trade continues to thrive. To address the problem of wildlife trade, we must understand why the business is booming.  Silvica identifies three pertinent issues among the various reasons why wildlife trade is occurring. 

  1. Availability of a ready marketplace

The demand for wild animals and their parts has frustrated the efforts taken to curb illegal wildlife trade globally. For instance, the Asian continent has the biggest marketplace for wildlife. From skins, ivory, snake skins, animal claws, shells to horns, the wildlife market in Asia is so diverse.

International markets are often the destination for illegal wildlife trade. The wildlife and their parts may not be in high demand in their place of origin. Instead, there are highly on-demand in international markets. In many cases, people at the source experience widespread poverty that wildlife trade is a viable economic activity. Unless governments take proactive action to eliminate the existing wildlife marketplaces, wildlife trade will continue thriving. Wildlife stakeholders must ensure that custodians of wildlife get a competitive value for keeping wildlife.  

  1. Absence of adequate laws to combat wildlife trade

In places where wildlife trade is rampant, there aren’t appropriate laws to curb illegal wildlife trading. Even if the law is present, the implementation may be weak. As such, orchestrators of this trade eventually get away with the vice. Some nations hadn’t given priority to wildlife trading until recently. Moreover, the punishment for illegal wildlife trading is too lenient in comparison to the crime committed by the masterminds of illegal wildlife trading.

  1. Big money on offer

Illegal wildlife trading fetches enormous returns in the international markets. These returns encourage poachers to conduct this trade in pursuit of wealth. The greed for money has continuously been fueling the poaching industry for years.  In 2014, for instance, the cost of a rhino horn was about US$ 70,000 per kilogram. As long as big money is on offer, wildlife trading will continue flourishing.

The issues with wildlife trade

Wildlife trade has been identified as a significant threat to wildlife today. Illegal wildlife trading has several implications not just on wildlife populations, but also on the environment as well. We have identified five major issues that arise from the trade.

  1. Endangering species

Wildlife trading is known to diminish populations of wildlife species, consequently causing global and local wildlife extinction. When this illegal trade involves endangered species, the resulting poaching of these species can subject them to the risk of extinction. In any case, sustainability considerations are rare in wildlife trade. As such, it fuels the endangering of species that were previously not threatened. For instance, bushmeat poaching in Africa has significantly reduced the population of previously common species such as zebras and giraffes. Consequently, IUCN has placed the species under the endangered group.

  1. Biosecurity risks

Wildlife trade can pose serious health threats to human beings.  For instance, it can introduce deadly bacteria and viruses to humans who aren’t resistant to these disease-causing viruses and bacteria. Parasites and other disease-causing microorganisms often infest wildlife species in transit. Trafficking of these wildlife species can thus pose a severe biosecurity threat to humans as they may cause deadly zoonotic diseases. The latest zoonotic disease that has put the globe on a standstill is the novel coronavirus. As of April 29th, 2020, the virus had infected over 3 million people.

  1. Violence

Poachers with guns alongside other crude weapons fuel violence in wildlife areas.  These weapons kill not only wildlife populations, but also wildlife officials, rangers, police, and other people who may try to protect the wildlife. Wildlife rangers in the world over have been killed and maimed by poaches while in line of duty. Violence can escalate in cases where poachers are organized and heavily armed.

  1. Derails wildlife conservation efforts

Apart from the apparent negative biological implications of illegal wildlife trading, this trade has adverse effects on wildlife conservation efforts. Even with sound conservation policies in place, all the wildlife conservation efforts will become futile as long as the business persists. Because of this reason, most conservationists are calling for a global ban on wildlife trade

  1. Threat to wildlife

The reduction of wildlife species is ultimately the biggest issue with wildlife trade. The key reason why nations are spending a fortune on fighting illegal wildlife trading is that it poses the biggest threat to wildlife.  When wildlife threatened, the world’s heritage is in jeopardy. If unlawful poaching isn’t addressed effectively, there will be no wildlife roaming on the planet in the coming decades.

Conclusion

Wildlife trade is undoubtedly a vice that governments must confront head-on. This lucrative yet illegal trade has far-reaching implications that can affect vast populations of wildlife and the environment at large.  Worse still, the business is proving challenging to fight. The international community must stop this illegal wildlife trading to protect global wildlife populations. You should also take note that not all wildlife trade is illegal. Organizations and governments should work at communicating the legal wildlife trade as well.

The emergence of Covid-19 has increased the discussion of conditions arising from animals. Zoonotic diseases, also known as a zoonosis, are diseases transmitted by germs from animals to humans. The zoonotic diseases are caused by harmful germs such as bacteria, viruses, fungi, or parasites. Once these germs/pathogens enter the human body, they cause the development of illness. A worrying trend is the observation of the increasing number of zoonotic diseases. A study by CDC estimates that three in every four emerging diseases are infectious diseases and are transmitted from the animals to humans. Scientist argues that even healthy animals can carry germs that make humans sick.

Scientists have established the link between the destruction of nature and the emergence of zoonotic diseases. As humans encroach the natural ecosystems, the chances of transmission between animals and humans increase. Similarly, wet markets provide an increased opportunity for viruses and other pathogens to jump from animals to humans.

 Some examples of deadly zoonotic diseases include Ebola, Influenza, Covid-19, and SARS.

Ebola

           Ebola is an infectious disease that is caused by the Ebola virus, which is suspected of having originated from Central Africa. The Ebola virus disease was first identified in DRC in 1976. According to various studies, the Ebola virus originated from the gorillas and the chimpanzee. However, the CDC believes that the virus was transmitted through either infected bats or infected primates. It shifted from the primates to humans through human contact with infected blood fluids. The Ebola virus then spread from human to human by coming to close contact with the infected persons. 

           The common symptoms of Ebola virus diseases include muscle aches, sore throat, severe headaches, fever, vomiting, diarrhea, impaired liver, and kidney functioning, and general weakness of the body. Other severe symptoms include the internal bleeding of the gastrointestinal tract. Patients with internal bleeding cough up blood stains, vomiting blood, and there are bloodstains in their stools. This loss of blood and body fluids eventually causes deaths. However, if there is no internal bleeding, patients can recover between 7 and 14 days. According to the World Health Organization, the Ebola Virus disease has a fatality rate of 50% in some countries. In some areas, the fatality is as low as 25% or as high as 90% in stressful situations.

Influenza

           Influenza is an infectious disease caused by the H1N1 influenza virus. In 1918, Influenza became a global pandemic that killed approximately 50 million people within months. Influenza originated from birds and pigs and is said to have originated from South East Asia. Influenza spreads from person to person by breathing air droplets produced by infected persons. Also, the Influenza can be transmitted by touching germs from the objects and surfaces and then touching your nose, mouth, or eyes.

The symptoms of Influenza include common cold, sore throat, sneezing, headaches, aching muscles, persistent cough, nasal congestions, and fatigue. However, some populations may increase the risk factors for developing severe complications. For instance, the elderly and people with underlying health conditions are at risk of developing complications such as pneumonia, bronchitis, and heart problems that eventually cause deaths. On the other hand, the young and healthy persons infected by the virus are likely to recover between 7 to 14 days.

           It can be prevented through annual vaccination against the flu. Other methods used to contain the spread of Influenza include washing hands, avoiding overcrowded places, and covering the mouth when sneezing or coughing.

Covid-19

           The Covid-19 is a new infectious disease caused by the coronavirus, as it was first identified in December 2019 in Wuhan, China. Many researchers believe Covid-19 originated from persons coming into contact with bats infected by the coronavirus. The respiratory disease has flu-like symptoms. The symptoms include persistent cough, difficulty in breathing, fever, and sneezing. In severe cases, the lungs collapse, causing shortness of breath leading to death. The incubation period of the virus is between 5 and 14 days. However, people showing no symptoms can transmit the coronavirus to other persons if they come into close contact.

           Covid-19 is transmitted from person to person by breathing in air droplets from infected persons. Also, the people can pick up Covid-19 by touching coronavirus germs on objects and then touching their nose, eyes, or mouth. The vulnerable populations are the older person with age above 65 years and persons with underlying conditions. The young and healthy can recover from Covid-19 between 7 and 14 days.

As of April 2020, there was no vaccine capable of protecting people from getting Covid-19. Nevertheless, the process of developing a vaccine has begun clinical trials and is expected to be ready in early 2021. As such, people are encouraged to control the spread of Covid-19 by regularly washing hands, avoiding overcrowded places, reducing contact with the elderly and people with underlying conditions, keep at least one meter distance between persons, and staying at home.

SARS

           The Severe Acute Respiratory Syndrome disease (SARS) was first identified in China in 2003. The SARS was caused by a SARS coronavirus that originated from bats and later spread to other animals such as the civet cats. The SARS then started to transmit from persons to persons through breathing in air droplets from infected persons. Also, people could pick the SARS coronavirus by touching contaminated objects and surfaces and then touching their nose, eyes, and mouth. Kissing, sharing drinks, and skin contact are other ways that SARS can be transmitted from person to person.

           The symptoms of SARS include fever, diarrhea, shivering, headaches, malaise, and pain in the muscles, cough, and shortness of the breath. The SARS symptoms were similar to Influenza, and there was no diagnostic symptom that was individually associated with SARS. For instance, some individuals showed a fever in the first weeks, shortness of breath and dry cough on the second week, and eventually patients suffering from respiratory distress.

           No vaccine has been developed to prevent SARS. However, research on a vaccine is still ongoing. People are recommended to keep a distance with SARS symptoms and avoid traveling into areas with SARS outbreak.

           Animals are beneficial to human beings for a variety of reasons. However, in recent years the emergence of Zoonotic diseases has shown that animals are also capable of carrying pathogens and transmitting them to humans. Ebola, Covid-19, Influenza, and SARS are some of the deadly zoonotic diseases that originated from animals and later transmitted from persons to persons. The five diseases in this article are just a tip of the iceberg. There are dozens of deadly zoonotic diseases as highlighted by this article.

Most of these diseases are infectious, thus posing higher health risks to humans.
