The Global Oil Supply: Implications for Biodiversity?

The following is an overview of my recent lecture to the Linnean Society of London, which is named in honour of Carl Linneus, who among many other accolades has been described as “The father of modern taxonomy”, and is also considered as one of the founders of modern ecology. It is the world’s oldest active society for the biological and environmental sciences, and the roll call of its Fellows includes such great names as Charles Darwin and Alfred Russel Wallace.

The link between the global oil supply and biodiversity is not directly causal; rather, the two are elements of a broader and more integrated picture. Of the energy used by humans on Earth, crude oil represents the lion’s share (33%), followed closely by coal (30%), with gas in third place at 24%. Traversing the gamut of energy sources, we find nuclear energy (4%) and hydro-power (7%), with renewable energy (wind and solar) entering the final furlong at just above 2% of total energy use, meaning that around 88% of our energy is furnished by the fossil fuels. 100 years ago, oil could be produced at an EROEI of 100, while this is now nearer to 17 as a global average, and falling, as unconventional oil sources increasingly make up for the decline in conventional production. So it’s becoming increasingly harder to maintain the oil flow into global civilization.
