Why Conserve Biodiversity?
Why does it matter if species and pristine habitats are disappearing before our eyes?
Why do we bother to conserve anything? For most of those actively involved in conservation, our motivation is clear. We conserve nature as an ethical choice. We value the wild species and natural habitats with which we share this planet, not solely for what they give us, but also as having their own right to exist and flourish. We reject any notion that suggests that species should pay their own way in order to have a right to be here on the Earth with us.
Recognising the intrinsic value of nature
This intrinsic value of nature has been formally recognized by governments, for example in the Preamble to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) agreed in 1973 and its call for urgent action:
- Recognizing that wild fauna and flora in their many beautiful and varied forms are an irreplaceable part of the natural systems of the earth which must be protected for this and the generations to come;
- Consciousof the ever-growing value of wild fauna and flora from aesthetic, scientific, cultural, recreational and economic points of view;
- Recognizingthat peoples and States are and should be the best protectors of their own wild fauna and flora;
- Recognizing, in addition, that international co-operation is essential for the protection of certain species of wild fauna and flora against over-exploitation through international trade.
Beyond intrinsic value
However, the Preamble to CITES also recognizes other values of nature beyond the intrinsic. It refers to the aesthetic, scientific, recreational and economic values of nature. All of these are values placed on nature by humans.
In recent years, as conservationists have fought harder and harder to convince others of the need for nature conservation, we have appealed more and more to the utilitarian or instrumental values of nature, because we believe, rightly or wrongly, that arguments for conservation based on intrinsic values alone will not be sufficient to persuade, for example, governments or the private sector.
What nature gives us
There is no question that nature does provide benefits to people, including economic benefits. For example, forest conserved on water catchments maintains a year-round flow of clean water in streams. Many species provide us with products that are commercially valuable, for example as medicine, food, or products such as wood. And there are whole industries based on nature, such as ecotourism, fisheries and forestry. Natural ecosystems also play critical roles in sequestering carbon (thus reducing climate change impacts), or preventing soil erosion, or providing coastline defence (for example coral reefs and mangroves), or providing for spiritual enrichment and recreational enjoyment (so-called cultural services).
Local and global benefits
Conservation programmes can bring benefits for local communities, but sometimes the human beneficiaries of ecosystem services are far distant from the site of the conservation programme (as with climate regulation services for example). All these benefits that nature provides to humanity go by the technical term “ecosystem services”. More recently conservationists have started to use the term “natural capital” to refer to “capital” needed in terms of species and ecosystems in order to deliver the “ecosystem services” on which people depend.
Debates have become particularly heated when some proponents of natural capital have started to put monetary values on nature. Many of those that emphasise intrinsic values believe that this is ethically wrong. The danger of putting a monetary value on, say, a forest, is that it could give justification for destroying that forest if the monetary value of an alternative, destructive land-use is higher. This is not an academic debate. At the time of writing, there is a proposal to destroy the Atewa Forest in Ghana because it is sitting on top of a valuable bauxite deposit. But the Atewa Forest includes many species that occur nowhere else in the world. Mining the bauxite will mean extinction for these species.
A pragmatic approach
As a result of such instances, many intrinsic conservationists have become very wary of terms such as “ecosystem services” or “natural capital”. But to be fair, by no means all proponents of ecosystem services or natural capital arguments support putting a monetary value on nature; rather they feel that such concepts are a useful way to persuade decision-makers of the multiple reasons for conserving nature.
The fierce debate on nature’s values still rages on. Is it still realistic to expect that we can help to protect nature for nature’s sake, for the intrinsic value of other species? Or is couching conservation in economic terms – natural capital, ecosystem services – the only realistic hope there is for protecting biodiversity?
The fact that this debate is even happening is a demonstration of the stark disconnection from nature which has taken place in our society – surely, we shouldn’t need to be convinced of the value of nature, and yet evidence shows that we do. Increasingly in Synchronicity Earth we wonder if this is a productive discussion. We should unashamedly embrace all of nature’s values. But we also seek to change hearts and minds to embrace nature’s intrinsic values, and to insist that nature should never be required to pay its own way.
