How Economic and Environmental Stability Influence Population Growth and Decline

Population changes, both explosions and declines, significantly impact our environment and economies worldwide. To truly address economic and environmental sustainability, we must acknowledge the relationship between population trends and our technological advances.

Historically, the idea of a population explosion came from Thomas Malthus in 1798. He warned that population growth would surpass food production. This concern resurfaced in the 1960s through Paul R. Ehrlich, who highlighted potential resource shortages. While they faced criticism for predicting crises that didn’t occur, their views stress a critical point: population growth can strain our resources and ecosystems.

For instance, agricultural technology has evolved, improving food production to meet global needs. However, as the population grows, issues like climate change and biodiversity loss become more pressing. Surprisingly, recent data shows that although the population growth rate now is slower than it was in the 1960s, environmental challenges have intensified.

Looking at the economy, unified growth theory explains how societies transition from high population growth and low income to stabilized populations and increased prosperity. This transition often hinges on technological advancement. Countries investing in green technologies can improve their economies and reduce environmental footprints. Yet, upfront costs and short-term thinking can hinder progress.

The flip side is population decline. Countries facing decreases often exhibit aging populations, which can lead to economic instability. In fact, around 63 countries have already hit their population peaks, with 48 more expected to follow soon. Projections estimate the global population will hit 10.2 billion by 2100, but a rapid decline in fertility rates raises concerns about lengthy zero-growth periods.

Studies show that declining populations can lead to a slower economic output. Wealthier nations particularly feel this impact, as an increasing elderly population can diminish GDP growth. For example, the more elderly individuals in a country, the lower the overall economic output tends to be.

These challenges are compounded by a disconnected approach to addressing both population dynamics and environmental issues. In affluent countries, declining birth rates can trigger a retreat from sustainable practices. Historically, wealthy nations led innovations in green technology, but economic pressures often prompt a short-sighted focus on immediate gains over long-term solutions.

In the U.S., for example, rising anxiety about immigration and economic stability has resulted in stricter immigration policies, potentially exacerbating population decline. This reactionary stance limits the influx of younger workers who could bolster the economy. Additionally, a shift back toward fossil fuels rather than renewable energy sources raises concerns about worsening climate impacts.

Climate-related costs are already significant, amounting to 2% of global GDP. This figure may grow to between 2% to 21% of a nation’s income by the century’s end due to ongoing environmental degradation. The rise of artificial intelligence also complicates matters, as it could either replace jobs or hinder labor supply, further straining economies facing demographic shifts.

Canada faces similar hurdles. With already low fertility rates, a recent decrease in immigration targets by 19% reflects economic tension. Moves away from carbon taxes and possible extensions of pipeline infrastructure could delay crucial transitions to greener policies.

In recent elections, environmental discussions have frequently been overshadowed by economic concerns. To navigate these interconnected crises, Canada and other wealthy nations must focus on long-term solutions that blend economic growth with environmental sustainability. The United Nations Sustainable Development Goals provide frameworks for achieving these interconnected objectives, but they require a commitment to addressing population dynamics within the broader context of economic and environmental policies.

Strong momentum exists among scientists, companies, and communities advocating for sustainable development. However, the current climate of economic uncertainty must not derail this progress. Public pressure is crucial to reinvigorate discussions about long-term, sustainable strategies to tackle these urgent issues.
