Book review – Planetary Accounting: Quantifying How to Live Within Planetary Limits at Different Scales of Human Activity

7-minute read

What I am about to write is probably going to upset many people, but… I am growing frustrated with the narrative of much of the environmental movement. Taking to the streets to protest and demand change, to “do something!”, is all fine and dandy, but it is also a bit hypocritical. It fosters a narrative in which the onus is always on others and it begs the counter-question: “what are you willing to give up?”. That is the hard question.

As a colloquial term that is all snazzy, but are we actually leaving a tangible trace in the rock record to signal a transition to a new period?

Book review – Slime: How Algae Created Us, Plague Us, and Just Might Save Us

6-minute read

In Algae We Trust. That might just as well have been the subtitle of this book. In Slime (published in the UK as Bloom, but I read the US version), author Ruth Kassinger writes of the many fundamental, often eye-opening roles that algae play in our ecosystems. But she also travels around the world to talk to farmers, scientists, and inventors. From food to plastics to fuel, entrepreneurs are discovering that these little green powerhouses hold immense biotechnological potential.
