A summary of our 2025 study https://www.mdpi.com/2076-2615/15/22/3256 on the contributions of animal agriculture to climate change and broader environmental harms. The findings suggest that, globally, animal agriculture accounts for 12 - 20% of greenhouse gas emissions annually, and probably more. In light of the forecasted failure to keep warming to 1.5 °C above pre-industrial averages, policy...

56 billion animals are killed every year for their meat, but at what cost?
This documentary exposes the impact the animal agriculture industry not only has on our planet in terms of climate change & global warming, but also the millions of species we share it with.
It also sheds a light on what we can do to change this - veganism, reducing meat consumption, and being more organic in our ...

We are currently living through the sixth mass extinction since fossil records began. This video describes previous mass extinction events and the causes of the current one - mainly habitat destruction for livestock production, pollution and climate change. Some 1/3 of all species are expected to go extinct, with some ecosystems, such as coral reefs, most severely affected. People will also be ...

The human-caused (anthropogenic) rate of species extinction is already 1,000 times more rapid than the ‘natural’ rate of extinction typical of Earth’s long-term history, with the result that we are currently living through one of the very few mass extinctions to date. It is clear that climate change represents the greatest threat to life on Earth for many millennia.
Given the urgency with whi...

The human-caused (anthropogenic) rate of species extinction is already 1 000 times more rapid than the “natural” rate of extinction typical of Earth’s long-term history. It is clear that climate change represents the greatest threat to life on Earth for many millennia. Given the urgency with which we must reduce the size of our collective ecological footprint, it is remarkable that so little at...

There are around 160 million farmed animals based in New Zealand. The heavy national footprint of animal agriculture within New Zealand has had devastating impacts for its environment, public health, and animal welfare. This report describes how, and why, a transition to a cleaner, greener, plant-based future, can be achieved. Most of the concerns are applicable to any country, as are the solut...

To what extent should we protect animals’ rights? How much do animal lives matter, and why? How far should we go to protect animals? On 24th April 2022 I was asked to address these topics, within the ‘Choral contemplation’ series arranged by Somerville College at the University of Oxford. This was my presentation (albeit delivered within the beautiful surrounds of the Somerville College Chapel).
