How to Safeguard Our Natural Capital: A Call to Action
Written on
Understanding Natural Capital
Human society often prioritizes its immediate needs, leading to the gradual degradation of the very foundations of our existence. We seem to operate under the illusion that the universe exists solely to serve us.
Scientists have termed this current era the Anthropocene, a period defined by significant human activity, extensive energy consumption, and unparalleled impacts on our planet. While our intelligence has enabled us to create impressive technologies and innovative machines, we must question the wisdom of undermining the very resources that support us.
Is it truly wise to sever the branch upon which we rely?
For years, we have been systematically depleting the natural capital that underpins human well-being. It is imperative that we find sustainable ways to address our needs without harming our environment.
As Ban Ki-moon, the former UN Secretary-General, famously stated: “We are using resources as if we had two planets, not one. There can be no ‘plan B’ because there is no ‘planet B.’”
Identifying Environmental Stressors
How do we determine if we have overextended our use of natural capital? What measures can we adopt to ensure the sustainability of this vital resource?
Signs of environmental stress are increasingly apparent and manifest in various forms. They may include prolonged dry spells, frequent flooding, or wildfires. Other indicators might be declining crop yields without clear reasons, unusual odors, or a noticeable absence of birdsong and blooming flowers in spring.
Environmental stress can be categorized into three types: loss of quantity, quality, and diversity. Let's delve into these categories.

Loss of Quantity
Human activities exert immense pressure on both our environment and the habitats of various species. Notable examples include the Sumatran elephant, the Asian tiger, and the polar bear, all facing extinction. While these animals are easy to monitor, countless smaller species, such as bees and butterflies, are also vanishing. A decline in rainfall further exemplifies the loss of quantity in our natural resources, leading to drought and ecological damage.
Loss of Quality
Critical resources like water, soil, and air are increasingly showing signs of degradation. For instance, river pollution threatens drinking water supplies, while the erosion of topsoil diminishes agricultural yields and food security. Air pollution is linked to rising cases of respiratory diseases. Although these resources may still exist, their ability to provide the services we depend on is diminishing.
Loss of Diversity
Forests and oceans are vital reservoirs of genetic diversity. The next major medical breakthrough, whether a cure for cancer or a safeguard against pandemics like COVID-19, may lie hidden within these diverse ecosystems. Plantations often lack the biodiversity of untouched forests, proving that mere quantity cannot replace the richness of diversity. A varied landscape is essential for sustaining different plant and animal species.
These three types of loss are interconnected, with one often triggering another. For example, diminished water quality can lead to shortages, while the extinction of species reduces biodiversity and the degradation of soil affects food production.
Three Principles for Habitat Protection
To safeguard our planet, we must adhere to three fundamental principles. While they may not rectify the damage already done, they can help establish a stable foundation for future life and development.
Limit Reliance on Geological Capital
We heavily depend on geological resources like minerals and fossil fuels, which are finite. Once depleted, these resources take millions of years to regenerate. The combustion of fossil fuels releases carbon accumulated over eons, exacerbating climate change. Minerals, essential for modern industry, must be utilized judiciously and recycled from existing products.
Focus on Renewing Natural Capital
Not all natural resources are geological; many can renew themselves naturally. Renewable resources, such as water and soil, provide a sustainable foundation for human development. For example, forests yield food, fiber, and numerous ecosystem services, while domesticated animals contribute to food supplies. The sun, our most important energy source, is available everywhere.
Observe Ecosystem Resilience
Our basic needs compel us to utilize resources, but we often exceed our fair share, risking ecosystem stability. Natural systems not only produce essential raw materials but also absorb the waste we generate. By respecting ecological limits and allowing ecosystems time to recover, we can rely on their benefits indefinitely. This cyclical nature of life on Earth is truly remarkable.
We are placing immense pressure on our environment, evident in the loss of natural capital's quantity, quality, and diversity. Transitioning from an overreliance on geological resources to more sustainable options like sunlight, wind, and water is crucial. We must adopt practices that align with the resilience of natural systems and create cycles for recycling materials to ensure ongoing prosperity.
Despite our understanding of environmental issues, we often find ourselves in a pattern of measurement rather than taking action. Why do we continue to observe and document losses instead of implementing change?
Given the stakes involved, why aren't we applying these principles in our daily lives? If you possessed a duck that laid golden eggs, would you choose to harm it?
