Archive 2009 Forum Paul Mahony Some Environmental Impacts of Animal Agriculture

BCCAG member Paul Mahony provides an overview of the issue and presents the facts as they are in his well-researched articles on “Some Environmental Impacts of Animal Agriculture”.


BCCAG member Paul Mahony has been presenting around Melbourne on the enormous and often overlooked, climate change impacts of animal agriculture.

Some key items from his presentation are:


  • Climate change is real
  • Humans are having a massive impact


  • Inherent inefficiency
  • Scale
  • Greenhouse gases and other warming agents
  • Deforestation
  • Nutrition

Livestock needs to be part of the “main game”, because if we ignore it, all other efforts to overcome climate change will be futile.

A set of handouts from his comprehensive presentation can be found HERE .

Two of Paul’s earlier articles, relating to some of the material in the presentation, can be found here:

At the 2009 Sustainable Living Festival in Melbourne, Vegetarian Network Victoria (VNV) launched its new booklet highlighting the effects of animal-based food products on our planet.

The 16 page report deals with the issues of climate change, land exhaustion, water usage, species extinction, ocean depletion and others stemming from human dietary choices.

VNV President Mark Doneddu said, “Never before in our history have we been faced with so many environmental problems as right now. The simplest way for us to address this is to switch to a plant-based diet.” The report contains information from leading research bodies including the CSIRO, the Food and Agriculture Organization of the United Nations, and the Intergovernmental Panel on Climate Change, and can be accessed here: ‘Eating up the World: the Environmental Consequences of Human Food Choices’.
