Chapter 1: What is ecological debt and why is it important?
What is ecological debt? Thanks for asking. With World Environment Day coming up on the 5th of June 2022, let's take a moment to consider a concept which highlights both the scale of the climate crisis and equalities between different areas of the world. Discussions around ecological debt are closely linked to those of overshoot and the overuse of planet Earth's resources.
As regular listeners know, humans have now long been depleting Earth's resources far quicker than the planet is able to generate them. We discussed Earth Overshoot Day in a past episode, and it's gotten earlier and earlier every year. The only exception was 2020 due to COVID-related measures, but in 2021 the previous trend resumed.
Every year we continue to consume too many resources and pollute the planet. If we consider that as mounting ecological debt, let's say we're now paying interest It takes the form of extreme weather events, food shortages, the disappearance of other species, unremedied environmental degradation, and the buildup of CO2 in the atmosphere.
All this ecological debt is carried forward to future generations. Indeed, and it's worked its way into international debates since the 1990s when the climate crisis started gaining increased attention.
Chapter 2: How does ecological debt highlight inequalities between North and South?
It's to do with the imbalance between industrialized countries in the Northern Hemisphere and developing ones in the Southern Hemisphere. If you look back at history, many wealthier countries actually built themselves up at the expense of poorer ones, often including their former colonies.
That has taken the form of outsourcing production, depositing waste and pillaging resources for example, thereby forcing the ecological burden of their development onto other countries. How big of a North-South divide are we looking at? A recent groundbreaking study published in Lancet Planetary Health sought to assign responsibility for environmental damage over the last 50 years.
It found that high-income countries were overwhelmingly responsible for the majority of global ecological damage. The US was the worst culprit, accounting for 27% of all excess material use. The EU wasn't far behind, with a combined 25% among its member countries.
Chapter 3: What are the major contributors to global ecological damage?
That included the UK, as the analysis period was before Brexit. Other wealthy countries like Australia, Canada, Saudi Arabia and Japan also contributed significantly. But southern hemisphere countries were only responsible for 8% in total, highlighting the stark difference.
The study's authors insisted that high-income countries drastically need to reduce their resource consumption to sustainable levels. You could say they owe it to the rest of the world because of their ecological debt. It's a wrong that needs to be put right.
Chapter 4: How can high-income countries address their ecological debt?
Northern hemisphere countries developed more quickly, with others in poorer parts of the world paying the price. But the definition of ecological debt is somewhat abstract, so it's hard to put any precise figure on the damage done. That has also made it challenging to get on the political agenda with concrete measures. There you have it. Now you know what ecological debt is.
