Climate Change

The use of animals to convert plant proteins and nutrients into meat, milk, eggs and other animal products is enormously inefficient (see (1),(2)). High inputs are required (land, water, chemical fertilizers, pesticides) and high outputs are generated (greenhouse gases, acidifying gases, eutrophying substances) (see (1),(2)). On the one hand, livestock production contributes significantly to climate change through its direct greenhouse gas emissions and land lost to carbon sequestration. On the other hand, habitats are minimized, animals and plants are displaced and killed, complete ecosystems are destroyed and species are exterminated due to forest clearing, high water consumption, acidifying gases, eutrophying and toxic substances. This ultimately leads to a loss of biodiversity.

Climate change and the loss of biodiversity are closely related and mutually reinforcing (positive feedback).

 

The figures and calculations on the share of animal agriculture in climate change differ widely. The most common and at the same time smallest figure (14.5%) comes from the Food and Agriculture Organization of the United Nations (FAO). Here it must be taken into account that the FAO is steered and finan­ced by all global animal industries.

The following slides provide an overview of the individual analyses, their calculations and issues.
