The Last Hours of Ancient Sunlight by Thom Hartmann is a groundbreaking exploration of humanity's relationship with the Earth, examining how the rapid consumption of fossil fuels and natural resources is reshaping our planet and challenging the future of civilisation.
Hartmann combines environmental science, history, anthropology, economics, and politics to argue that modern society is living on vast stores of "ancient sunlight"—the energy preserved in fossil fuels over millions of years. He explores how dependence on these finite resources has transformed human culture and considers what changes may be needed to create a more sustainable future.
The book explores:
- Climate change and global environmental challenges
- Fossil fuels and energy consumption
- Sustainability and renewable resources
- Human history and civilisation
- Ecology, economics, and environmental responsibility
- Practical approaches to a more sustainable future
This title will appeal to readers interested in:

Written in an engaging and accessible style, The Last Hours of Ancient Sunlight challenges readers to reconsider humanity's impact on the natural world while offering hope through practical solutions and a renewed appreciation of ecological balance.
