Why should we strive to conserve biodiversity? I believe that If we do not, pathogens will find space to live among us. And when they do, our public health might be in danger. Hear me out.

No one knows the exact origins of coronavirus (Covid-19). Regardless, many people believe that it originated from Wuhan China, mainly because the first cases had linkages with a wet market in the area. Regardless, scientists know that the SARS-CoV-2 is common in bat populations. The virus somehow managed to infect humans. Like AIDS, SARS, Ebola, and some other infectious epidemics, the coronavirus is a zoonotic disease.

Think about it; the human body has trillions of microorganisms. How many more microorganisms exist within other plants and animals? I do not know, but I guess that it is undoubtedly more than quadrillions, or the next ‘llion’! And some of those microorganisms are pathogens, meaning that they cause diseases.

As we get closer to biodiversity, we expose ourselves to the pathogens

Human activities like urbanization, agriculture, logging, mining, and population growth trigger the destruction of biodiversity.

It is the destruction of biodiversity that creates conditions for new diseases. Tropical forests and wildlands have various plants and animals, and these living things harbor a variety of viruses. As we tamper with biodiversity, we get closer to more and more microbes.

Humans disrupt the ecosystem by killing animals and destroying habitats. When that happens, the viruses (and other microbes) that used to live in the animals and habitats will require new hosts. Often, the new hosts are us.

To reiterate, killing all the biodiversity will not get rid of the microbes. Inevitably, a few microbes may go extinct, but a significant number will look for alternative hosts. Humans will make a right candidate for alternative hosts because we are spread all over the earth.

The hidden cost of human economic development is exposure to zoonotic diseases. Rarely do environmental impact assessments capture this enormous cost. If you want to argue about the costs of zoonotic diseases, refer to how coronavirus has put the world at a halt.

Conserving biodiversity for human health is pertinent.

Researchers believe that pathogens are crossing from animals to humans at an alarming rate. The US Centers for Disease Control and Prevention (CDC) estimates that 75% of new emerging diseases are zoonotic. The coronavirus is just a tip of the iceberg, and more dangerous infectious diseases may arise if we do not put our act together.

We believe that conserving biodiversity will have positive outcomes for human health. As such, governments and non-governmental organizations should ensure enough land is set for protected areas. Species and their associated microbes will thrive in protected areas

I am not saying that maintaining protected areas will automatically mean that we will have no new zoonotic diseases. But yes, the risks will reduce. We should accept that humans are part of the earth system. In the bigger scheme of things, our ecological function is as crucial as the persistent mosquito.

Forests play a vital role in maintaining a sound environment, thanks to the fact that they contain the most extensive animal and plant diversity. Better still, forests have billions of trees that are particularly essential for absorbing carbon dioxide, thus helping to address the contemporary challenge of climate change.

Forests cover about 30% of the landmass on earth. However, most of the forest sites face various challenges that threaten their very existence. As such, we should all support the conservation of the world’s forest. We have outlined some of the important forests in the world.

The Expansive Amazon Rainforest

About 10% of the global biodiversity is in the Amazon (Source, WWF)

The massive rainforest lies on a territory stretching across nine nations.  It is the world’s largest rainforest since it represents over half of the rainforests in the world. Approximately 70% of the rainforest covers the Brazilian territory, although there is a significant part of the forest in Peru. Initially, the forest spread on a total area of approximately 7 million sq. Km (2.7 million sq mile).

Nonetheless, the forest is today estimated to cover an area of about 5.5 million sq. Km (2.12 sq. miles), thanks to heavy logging that has diminished the forest cover in the previous decades.  The Amazon Rainforest is considered critical since it hosts valuable freshwater resources alongside a wealth of diversity. Moreover, the rainforest plays a vital role in global biodiversity. Still, the forest is a carbon sink and hence offers essential ecological services.

The biodiversity of Congo Forest

As the world’s 2nd most extensive tropical forest, the Congo Forest forms a quarter of the earth’s remaining tropical forests. It covers an estimated area of 1.9 million sq. Kms (734,000 sq. miles). The Congo Forest is essential for a myriad of reasons. First, it houses 10,000 plant species, hundreds of mammals, and over 1,000 bird species. Secondly, the vast tropical forest is home to the world’s largest ape species, namely the Bonobo, gorilla, and chimpanzee. Besides playing a vital role in global diversity, the forest is home to over 24 million people who live within the forest area. Most of these people depend entirely on it for their livelihood.

The Coniferous East-Siberian Taiga

Located in East-Siberia, this vast coniferous forest stretches across a land area of about 4 million km sq. The forest is remarkably essential owing to its diversity of flora and fauna. The forest isn’t just the largest forest reserve in Europe, but also the 5th largest forest reserve worldwide. Furthermore, it hosts thousands of plant and animal species, most of which can only be seen here (endemic). It is also the only forest that stretches between tundra in the North and a group of temperate forests in the south.

The Scandinavian & Russian Taiga, a multipurpose forest complex

The forest is ranked as Europe’s largest eco-region, covering approximately 2 million sq. Kilometers (772,000 sq. miles). It spreads across Norway, Sweden, western Russia, and Finland.  The forest covers roughly a third of the European continent. It is crucial as a global ecological spot, thanks to the fact that it absorbs massive carbon dioxide emissions. The forest is specifically vital because it offers an extraordinary nesting habitat for thousands of bird species. It is also a haven for mining, tourism, and fossil fuel exploration.

The Sinharaja Forest, a World Heritage Site

The Sinharaja forest is the largest in Sri Lanka, with an area of 88 Km2 (34 miles2). It is also the country’s only remaining tropical rainforest. The forest is a significant part of Sri Lanka and the universe at large. Marjory because of its extraordinary biodiversity as it houses several species of endangered wildlife. It contains over half of Sri Lanka’s endemic mammals and butterflies. In 1988, UNESCO listed it as a World Heritage site thanks to its valuable, rich ecosystems and diverse living heritage. The forest boasts over 154 bird species that have been known to coexist in feeding flocks.

The Picturesque Mindo-Nambillo Forest

The sprawling, beautiful tropical forest is situated in Ecuador. It is one of Latin America’s most important ecological sites. Moreover, it is an incredible tourist attraction that keeps millions of travelers coming to Ecuador. The present-day tropical forest is a remarkably beautiful private reserve, which houses countless plants, birds, and mammal species. It is a treasure to behold, courtesy of the more than 450 bird species that live in the forest. It further houses a wide array of orchids.

The Avatar-inspiring Daintree Forest

Daintree forest is the world’s oldest rainforest, and it forms an integral part of the Australian treasure. The rainforest is a remarkable conservation center for birds, plants, and other mammals. For example, it houses the largest concentration of saltwater crocodiles in the universe.  It has the highest number of threatened animals and plant species.  The 1200 Km2 (463 square miles) rainforest was used as an inspiration for ‘Avatar’- one of the world’s best-selling movies.

The Pristine Xishuangbanna Rainforest

Located in China, this beautiful tropical rainforest is one of Asia’s biggest and most important forests. It is the world’s only living museum of flora and fauna. The 2500 Km2 (967 square miles) forest is also a center for ecosystem research for the Chinese government.  It has the most significant number of endangered plants and animal species in Asia. The forest is further home to multiple primitive villages that allows humans to coexist with wildlife.

Sundarbans, a Vital Mangrove Forest in Asia

The mangrove rainforest is located along with the coastal parts of the mighty Bay of Bengal. Due to its unmatched biodiversity, the forest has become highly significant as a conservation area. It has the widest variety of mangroves than any mangrove rainforest in the world.  The forest is a crucial natural wildlife spot. It has vast numbers of water monitor lizards and Bengal tigers, not to mention a variety of endangered species living in the mangrove rainforest.

The Endemic Valdivian Rainforest

Located in South America, the 250,000 Km2 (95,800 square miles) temperate rainforest is South America’s only rainforest. It houses the Andean Mountains, which add plenty of biodiversity to it. The forest is one of the world’s most important forests since it houses several fascinating creatures like the Kodkod and the southern Pudu.  Its vegetation comprises a variety of rare trees, such as the endangered Monkey Puzzle Tree. Approximately half of the woody species in the forest are endemic to the region

Forests remain crucial systems that support our lives. On the surface, forests appear similar as they encompass a group of trees. However, each forest has its unique composition of plants, animals, and microorganisms. Some important forests in the world are facing threats ranging from human encroachment to deforestation. Others like Borneo and New Guinea forests face a challenge from palm oil production. We must act to conserve the important forests of the world.
