Danjugan Island Marine Biodiversity – a genuine ecotourism experience in Negros Occidental, Philippines

A guest post from Philippine Daily Inquirer columnist Cielito M. Habito. 

Consider the following: Southeast Asia occupies a mere 3 percent of the earth’s total surface, yet is home to 20 percent of all known species of plants and animals on the planet. The region possesses 284,000 square kilometers, or one-third, of all of the earth’s coral reefs, and as divers will attest, what we have are among the most diverse, and the most beautiful, in the world. The mountains, jungles, lakes, rivers and seas of our region make up one of the biggest pools of biological diversity in the world.

Three Southeast Asian countries—Indonesia, Malaysia and the Philippines—are among the world’s 17 megadiverse countries, a term applied to those that harbor the majority of the earth’s species, and large numbers of endemic (native) species. But there are also “biodiversity hot spots”—geographic areas with significant levels of biodiversity under threat from humans. Such “hot spots” are distinguished by having at least 1,500 endemic plant species, and have lost at least 70 percent of primary vegetation. And it is alarming that among the three Southeast Asian megadiverse countries, only the Philippines is in the biodiversity hot spot list. We are, unlike our neighbors, causing the destruction and disappearance of plant and animal life at a rate so fast as to imperil our environment’s ability to sustain human life.

Human life is only one form of an estimated nine million life forms that inhabit our planet. Most of us understand that the myriad life forms all around us interconnect in simple and complex ways to one another, in an intricate “web of life.” The interconnections can be visible and obvious, as with predators and prey in the food chain. They can also be subtle, indirect or invisible, as when chemical reactions in certain organisms affect other organisms positively or negatively. For example, the class of plants called legumes develops nodules in their roots that host bacteria capable of converting nitrogen from the air into ammonia. As such, otherwise unusable nitrogen in the air is turned into useful compounds like amino acids, the building blocks of proteins, which are in turn vital to animal and human life.

In this intricate web of life, a change in one link of the food chain can lead to far-reaching disruptions elsewhere in the ecosystem. A 2011 study conducted by 24 scientists from six countries documented how the decline of large predators at the top of the food chain has disrupted ecosystems all over the planet. As observed by the study, large animals were once ubiquitous across the globe, and shaped the structure and dynamics of ecosystems. Their decline, largely caused by humans through hunting and habitat fragmentation, has had far-reaching and often surprising consequences, including changes in vegetation, wildfire frequency, infectious diseases, invasive species, water quality, and nutrient cycles.

A well-studied example of how human intervention can severely disrupt the natural equilibrium was the deliberate elimination of wolves in Yellowstone National Park in the United States between 1872 and 1926. When the wolves were gone, the elk population rose, and led to overgrazing of deciduous woody species such as aspen and cottonwood. Over the years, conditions in the park drastically deteriorated, leading park authorities to trap and move the elk, and eventually, kill them. Elimination of wolves also led to a dramatic increase in the population of coyotes, which in turn adversely impacted the population of the pronghorn antelope. Studies on the park’s ecosystem spanning decades led to the decision to reintroduce wolves into Yellowstone in 1995. This has since led to a decline in the elk and coyote populations, which in turn had further effects on the population of foxes, and on various forms of plant and insect life in the park. The new and often unexpected impacts of the reintroduction of wolves continue to unfold to this day.

There are many other similar documented examples elsewhere in the world of ecological disruption arising from human intervention into the biological system on land and in the seas. The lesson is clear: Compromising biological diversity and the complex interrelations therein will have unforeseen and far-reaching undesirable impacts that are bound to hit back on us humans in ways hard to anticipate. The World Wide Fund for Nature asserts: “Biodiversity underpins the health of the planet and has a direct impact on all our lives. Put simply, reduced biodiversity means millions of people face a future where food supplies are more vulnerable to pests and disease, and where fresh water is in irregular or short supply.”

The Philippines has the distinction of hosting the Asean region’s knowledge and advocacy center for biodiversity conservation, at the University of the Philippines Los Baños campus in Laguna. Established in 2005 with initial funding support from the European Commission, the Asean Center for Biodiversity is now supported by the 10 member-states. In the second Asean Conference on Biodiversity that it organized in Bangkok last week, hundreds of scholars, government officials, stakeholders and advocates explored the links between biodiversity and human health, business and biodiversity, and how biodiversity permeates the global Agenda for Sustainable Development and its accompanying Sustainable Development Goals for 2030.

“A treasure trove of plant and animal life”—that’s how our part of the world is often described. Protecting that treasure is critical not just for the sake of the treasure per se, but also for the sake of our very welfare as human beings, now and far into the future.
