Pollinator decline will prove disastrous for the global economy

Large swaths of the global economy are heavily dependent on the fertilization of crops by pollinators. These essential contributors to our ecosystem, primarily insects, are facing significant threats from climate change and environmental degradation. The decline in pollinator populations is expected to have far-reaching effects that extend beyond agriculture and consumer goods, impacting sectors such as pharmaceuticals and financial services. Understanding the ramifications of this decline is crucial for safeguarding both our environment and economy.

### Insect Numbers Are Declining Rapidly

The decline in insect populations is alarming. A paper published in 2017 highlighted a staggering 76% drop in flying insect biomass across German nature reserves over a 27-year period. This startling figure is not an isolated incident but part of a broader global trend. Scientists attribute the decline to a myriad of environmental threats, predominantly climate change. As global temperatures rise, rainfall patterns shift, and extreme weather events become more frequent, insects find it increasingly challenging to survive.

The British Ecological Society indicates that the seasonal timing of plants is changing at four times the rate that insects can adapt, further compounding the problem. Agriculture plays a significant role in this crisis, particularly due to the widespread use of synthetic agrochemicals, such as neonicotinoid pesticides. These chemicals not only directly harm pollinator populations but can also cause long-term sublethal effects that impact their survival and reproduction. Although the UK government banned the use of neonicotinoids in 2018, exemptions have allowed their continued use, leaving pollinators vulnerable.

### Global Food Supply Chains Will Suffer Dramatically from Pollinator Loss

Pollinators are critical to global biodiversity, with insects making up 75% to 80% of all known animal species. This staggering number signifies how essential they are for food production. According to UK Research and Innovation (UKRI), over 75% of globally important crops require animal pollination. While staple crops like barley and wheat do not depend on pollinators, the majority of fruits, vegetables, nuts, and beans do. Consequently, a continued decline in pollinator populations poses a serious threat to global food supply chains, disrupting everything from production to distribution.

This impact will inevitably have a cascading effect on the consumer and foodservice sectors. A decline in agricultural output will lead to increased prices and reduced availability of essential food items. This situation will destabilize supply chains and threaten business models across these industries, causing economic ripple effects felt by consumers globally.

### Other Sectors Will Face Unexpected Consequences from Declining Insect Populations

Interestingly, the medical sector also relies on animal pollinators more than one might think. Approximately 25% of pharmaceuticals today are derived from medicinal plants, many of which are dependent on insect pollination. The plant-derived drug market is projected to be worth around $41 billion. A decline in pollinators means not only the loss of potential life-saving medicines but also untapped revenue potential for pharmaceutical companies.

The financial services sector is poised to face unexpected repercussions as well. Financial institutions that invest in agribusinesses, lend to farmers, or underwrite crop insurance will experience significant exposure as agricultural production declines. As revenues in the foodservice and consumer sectors dwindle, this can lead to broader implications for financial stability within these institutions. Moreover, sustainable finance initiatives and green bonds, which aim to support ecosystem conservation, may also be jeopardized by the decline of pollinators.

### To Maintain the Global Economy’s Stock of Natural Capital, We Must Protect Pollinators

Pollinators play a vital role in maintaining ecosystems that support human habitation worldwide. They contribute to the health of forests, which in turn purify drinking water, alleviate air pollution, and help manage flood risks. This makes them indispensable to our natural capital—a stock of natural assets that provide immense value to society. As the global economy increasingly recognizes the importance of natural capital, protecting pollinators becomes paramount.

To effectively safeguard pollinators and maintain our economy’s natural capital, collaborative efforts at every level are required. Policymakers must implement meaningful regulations to reduce the use of harmful agrochemicals and encourage sustainable farming practices. Likewise, businesses should invest in initiatives to conserve pollinator habitats and promote biodiversity. Finally, individuals can contribute by advocating for policies that support pollinator protection and by adopting practices that enhance local biodiversity, such as planting native flora.

### Conclusion

The decline of pollinators poses a profound threat not only to agriculture and food security but also to sectors as varied as healthcare and finance. As these essential insects continue to diminish, the implications become increasingly serious for the global economy. Investing in the protection and conservation of pollinators is not just an environmental imperative; it is an economic necessity. By addressing the multifaceted challenges they face, we can help to ensure a sustainable future for both our ecosystems and economies. Now more than ever, it’s essential to recognize that our well-being is intricately linked to the health of the natural world around us.
