What Happens If Gorillas Go Extinct?

What Happens If Gorillas Go Extinct? Impact on Rainforests and Wildlife.

What Happens If Gorillas Go Extinct? Gorillas are among the most majestic and ecologically important animals on our planet. Currently, four subspecies of gorillas exist in the wild: the western lowland gorilla, the Cross River gorilla, the eastern lowland gorilla, and the mountain gorilla. These species are classified as either Endangered or Critically Endangered on the IUCN Red List. Gorillas have natural habitats that include tropical or subtropical rainforests within Sub-Saharan Africa. While their habitat makes up a tiny portion of Africa’s landscape, gorillas can be found at a variety of altitudes.

The mountain gorilla, found only in the Virunga Massif and Bwindi Impenetrable National Park in Uganda, numbers just over 1,063 individuals. Mountain gorillas can survive between 2,200 and 4,300 metres (7,200–14,100 feet). Lowland gorillas can be found in the dense forests and swampy lowlands, some as close to sea level as possible. The western lowland gorilla can be found in central West Africa. The question facing conservationists, governments, and the global tourism industry is no longer abstract: What truly happens if gorillas go extinct?

Gorilla Trekking Tourism Collapses

The most immediate and quantifiable result of the extinction of gorillas will be the end of gorilla trekking tourism, which is worth millions of dollars in revenue and supports the economies of nations. For example, in Uganda, gorilla trekking in Bwindi Impenetrable National Park is the main revenue source for the economy through tourism activities. It costs $800 per person to go gorilla trekking in Uganda, while it takes $1,500 per person to trek gorillas in Volcanoes National Park in Rwanda.

If gorillas were to go extinct, the economic argument for preserving vast tracts of montane rainforest would largely disappear. Governments facing pressure from agricultural expansion and mining interests would find it far harder to justify protecting land that no longer generates tourism revenue. The forests themselves, home to chimpanzees, forest elephants, golden monkeys, and hundreds of bird species, would face dramatically increased deforestation pressure.

A Medical and Scientific Catastrophe

Gorillas share 98.3% of their DNA with humans, making them our closest relatives after chimpanzees and bonobos. This amazing genetic closeness has made the gorillas very useful in the fields of medicine and evolution. Research involving the immune system, disease resistance, and physiology of the gorillas has led to discoveries relating to respiratory disease, heart problems, and infection.

Like human beings, gorillas are vulnerable to many diseases, such as Ebola, respiratory syncytial virus, and even COVID-19. Studies on the biological response of gorillas to such diseases can be very useful for coming up with vaccines in the future. The loss of gorillas is the loss of a million-year-old window of opportunity for scientific research.

The Forest Architects Vanish

Gorillas are what ecologists call “keystone species”, animals whose presence shapes the entire structure of their habitat. A single gorilla consumes between 18 and 40 pounds of vegetation daily, feeding on fruits, leaves, bark, and stems. As they do this, they help spread the seeds of plants over huge distances via their faeces, becoming forest gardeners and helping plants and trees grow again.

Some species of plants in the Central African rainforest are totally dependent on the seeds being dispersed by gorillas. Without them, these plants would start dying out and eventually become extinct. This would mean the extinction of some insect, bird, and other mammal species that depend on these plants.

Cultural Loss and the Erosion of Indigenous Knowledge

The existence of gorillas is not only biologically relevant to the Congo Basin and the East African mountains; it is also culturally and folklore-wise intertwined into the life and existence of those indigenous communities. For instance, consider the Batwa people from Uganda who have coexisted with the gorillas even prior to the emergence of any kind of national parks.

The indigenous knowledge of the behaviour of the gorillas, the healing power of the forest trees, and the ecology is inimitable and unique. The extinction of gorillas would not only erase a species; it would accelerate the erosion of indigenous languages, practices, and relationships with the natural world that have no written record. The cultural dimension of this loss is one that conservation literature too rarely acknowledges.

Communities and economies would suffer deeply

The impact on humans caused by the extinction of gorillas will be enormous. In Uganda, Rwanda, and DRC, there are numerous individuals earning a living as a result of gorilla trekking, working as rangers, guides, porters, staff in lodges, sellers of crafts, and even drivers. The cost of just one permit for gorilla trekking in Rwanda is $1,500, and this amount is huge in the country’s economy.

The Bwindi Impenetrable Forest, located in Uganda, draws thousands of global visitors annually who engage in gorilla trekking. If the gorillas disappeared, so would this entire tourism economy. Schools built with permit revenues, hospitals funded through community sharing programmes, and jobs sustained by wildlife tourism would all be lost. Local communities that have invested in conservation because it benefits them would have nothing left to protect and every incentive to convert forest into farmland.

What Can Still Be Done

The story of gorilla conservation is not yet one of defeat. The mountain gorilla is, remarkably, the only great ape subspecies whose population is currently increasing, a testament to decades of intensive protection by organisations like the Dian Fossey Gorilla Fund, the International Gorilla Conservation Programme, and the Uganda Wildlife Authority. Anti-poaching patrols, veterinary intervention, community benefit-sharing from gorilla trekking revenue, and strict habitat protection have all contributed to this cautious recovery. From a low of approximately 620 individuals in the 1980s, mountain gorilla numbers have grown to over 1,063 today.

Gorilla tracking is one of the factors that help make this happen. Tourists, while on gorilla trekking tours in Bwindi Impenetrable National Park in Uganda and Volcanoes National Park in Rwanda, generate a significant amount of money from the purchase of permits, which is directed towards conservation efforts and development of the local communities. The system of creating revenue from wildlife and using that money to support the lives of the people living alongside that wildlife is the most sustainable form of conservation that has ever been created.

The Gorilla Is a Mirror

Ultimately, the question of what happens if gorillas go extinct is also a question about who we are. These animals communicate, grieve, form long-term bonds, use tools, play, and raise their young with tenderness observable to anyone who has spent time in their presence. Their extinction would not simply be a biodiversity statistic; it would represent a moral failure of the species that shares their DNA and holds the power to determine their fate. The rainforests of Central and East Africa, the communities that depend on them, and the global ecosystem that regulates our climate all have a stake in whether gorillas survive. Conservation is not a luxury reserved for wealthy nations; it is a shared obligation, and gorilla trekking tourism offers one of the most direct ways any individual can contribute to making it work.

The forest is still standing. The gorillas are still there. The question is whether we choose to keep it that way.
