Pollinator decline will prove disastrous for the global economy

Large swathes of the global economy are heavily dependent on the fertilization of crops by pollinators. Without them, we face a crisis that could severely impact both agricultural productivity and economic stability.

Pollination, primarily performed by insects such as bees, butterflies, and other small creatures, plays a crucial role in the fertilization of plants. However, these vital species are facing unprecedented threats due to climate change and environmental degradation. The consequences of declining pollinator populations extend beyond just agriculture, reaching into various sectors, including pharmaceuticals and financial services.

### The Current State of Pollinator Populations

Globally, insect populations are undergoing rapid decline. Anecdotal observations, such as fewer insect splatters on windshields compared to those of 30 years ago, are supported by scientific studies. For instance, research published in 2017 revealed a shocking 76% decline in flying insect biomass in some German nature reserves over a span of 27 years. This drastic reduction cannot be attributed to a singular cause, but rather is the result of multiple environmental challenges.

Climate change is a significant factor. Heating temperatures, changing rainfall patterns, and increased occurrences of extreme weather events threaten insect survival. One disturbing trend is that plants are adapting to these environmental changes at a rate four times faster than insects can, thereby adding more stress to their populations.

Another critical issue is the rise of intensive agriculture. The widespread use of synthetic agrochemicals, particularly neonicotinoid pesticides, has devastated insect populations around the world. While these chemicals are designed to protect crops, they often harm the very pollinators that are essential for crop fertilization. Although the UK government banned neonicotinoids in 2018, exemptions have been granted that keep pollinators at risk.

### The Impact on Global Food Supply Chains

Insects are estimated to comprise 75% to 80% of all known animal species, which means their decline is a significant concern for global biodiversity. The implications are dire not just for ecosystems but for the economy as well. Agriculture is the most affected sector; over 75% of globally important crops rely on animal pollination.

While grains like wheat and barley do not require pollinators, most fruits, vegetables, nuts, and beans do. A continued decline in pollinator populations could destabilize global food supply chains, with ripple effects reaching consumers and food service industries. This could lead to increased food prices and reduced availability of essential products.

### Broader Economic Repercussions

Beyond agriculture, various sectors will face unforeseen consequences due to declining insect populations. The medical sector, for one, relies heavily on animal pollinators. Approximately 25% of pharmaceuticals today are derived from medicinal plants often found in tropical rainforests, which depend on these crucial pollinators for their growth. Reports estimate that by 2024, the plant-derived drug market will be worth around $41 billion. The ongoing decline of pollinators threatens to stymie the discovery of new pharmaceuticals, resulting in a lost economic opportunity.

Financial services are also intricately tied to pollinator health. Institutions that invest in agribusiness, provide loans to farmers, or underwrite crop insurance will find themselves particularly vulnerable if agricultural production declines. Similarly, financial services tied to consumer sectors will experience the fallout from diminishing revenues in agriculture and food service.

Furthermore, sustainable finance options, like green bonds that promote ecosystem conservation, may see their viability challenged. As pollinators vanish, investments in these areas could also diminish, impacting the sustainability goals of these financial institutions.

### The Need for Action

Pollinators contribute to essential ecosystem services that support human existence. By fertilizing trees and nurturing forest health, pollinators enhance water purification, improve air quality, and reduce flooding risks. Their contributions encapsulate a vast portion of what is termed “natural capital,” the environment’s suite of services that provide value to society.

To preserve this invaluable natural capital, a concerted effort is required. Protecting pollinators should be a priority across multiple sectors, necessitating both policy actions and private sector initiatives. Governments need to regulate pesticide use more stringently, while businesses must embrace sustainable practices that help restore and maintain healthy ecosystems.

In summary, the decline of pollinators is a pressing issue that threatens not only biodiversity but also the economic framework that supports human society. By recognizing the deep connections between pollinator health and various economic sectors, we can engage in meaningful actions to protect these creatures and, in turn, safeguard our shared future. As we go forward, let us remember that our planet’s biological wealth is intricately tied to its economic health, and it is essential to safeguard both for a sustainable world ahead.
