“The Facts” about sustainability, the environment and your future.

Below are the facts stated in the film Cowspiracy and their references.  Which ever side you’re on it’s good to know them.   For example, one takeaway from the ideas presented is that we can resolve environmental problems, reform economic systems and still keep our cars, if we change our diet.  If you take that with a pinch of salt (ha ha) it actually sounds quite interesting.  Anyway that’s a conversation for another day.  Here are the facts:

Animal agriculture is responsible for 18% of greenhouse gas emissions, more than all transportation combined. [i]

Fao.org. Spotlight: Livestock impacts on the environment.

Transportation is responsible for 13% of all greenhouse gas emissions.

Greenhouse gas emissions from this sector primarily involve fossil fuels burned for road, rail, air, and marine transportation.

Livestock and their byproducts account for at least 32,000 million tons of carbon dioxide (CO2) per year, or 51% of all worldwide greenhouse gas emissions.

Director’s Note:

The science and research done on the true impacts of animal agriculture is always growing. The statistics used in the film were based on the information below.

We will continually update this list with further resources as they become available.

Although there may be fluctuations in numbers from year to year and from researcher to researcher, the fact remains that animal agriculture, as a whole, requires tremendous amounts of resources and is a leader in environmental degradation.
