Feature Map: Biodiversity in the South China Sea
We need only call to mind the first half of 2022 for an array of the extreme, energy-related global challenges we all face. Around the world, local versions of climate change effects—the temperatures, wildfires, droughts, storms, flooding—underscore how important it is for us to transition away from our overdependence on fossil fuels. And our energy sources don’t just have environmental implications but security ones as well. The Russian invasion of Ukraine is the latest rendition of the resource curse. At the heart of it all, fossil fuels are what enabled and amplified the murderous narcissism we see in Vladimir Putin and created a country with an unbalanced and unhealthy domestic economy able to profoundly destabilize energy flows and prices around the world.
The South China Sea (SCS) brings together its own assortment of these complex challenges and factors. Competing security concerns, resource needs, and nationalisms shape the motivations of the claimants. Much of the attention and conflict has centred on the oil and gas in the seabed. Estimates of SCS hydrocarbon volumes vary; only some of these resources are proven reserves that have been confirmed and measured, and are actually recoverable. But even in more generous assessments, the SCS only provides us with a small percentage of the global total of oil and gas reserves, and even less of the overall energy mix if we include non-fossil-fuel energy sources.
Beyond hydrocarbons, in a two-way tie with the adjacent Coral Triangle, the SCS has the highest level of marine biodiversity in the world. SCS fisheries feed and employ millions of people in the region. It’s true that conflict over these living marine resources also drives the territorial disputes in the region, and a wide variety of human activity degrades the SCS ecosystem. Yet drilling for hydrocarbons in the SCS threatens this vulnerable marine habitat even more, while also clearly contributing to geopolitical and security tensions in the region—and to climate change.
Given how destabilizing oil and gas pursuits have been for the SCS since the 1970s, we might ask ourselves whether we want to keep drilling for fossil fuels there. Do the costs and risks outweigh the benefits?
