There seems to be a strong focus on livestock at the moment. Greenpeace International has also entered the field now, with a new report, Ecological Livestock. Focusing on Europe, the report explores livestock production and consumption can be reduced to fit within ecological limits, such as biodiversity, climate change and water use.
The full report title is Ecological livestock: Options for reducing livestock production and consumption to fit within ecological limits, with a focus on Europe. Greenpeace Research Laboratories Technical Report.
