Climate Science

Climate change today is happening because human activities are sending greenhouse gases (GHG) into the atmosphere, disrupting a delicate balance that has supported life on earth for millions of years.

Animal agriculture in the U.S. accounts for as much as 51% of all greenhouse gases and is the leading cause of climate change. Animal agriculture on any scale cannot adequately sequester in the soil biology the Carbon Dioxide (CO2), Methane (CH4), and Nitrous Oxide (N2O) it produces. Methane is 25-100 times more destructive than CO2 on a 20 year timeframe. Nitrous oxide is 300 times more destructive to the atmosphere than CO2. The time taken for methane released into the atmosphere to reduce by approximately two-thirds is twelve years. Carbon dioxide takes 100 years or more to clear. Methane has increased in the atmosphere from 1,700 to 1,850 nanomoles since measurements were first taken in the 1980’s; that is 1,600 parts per billion (ppb) up to 1,800 ppb. Reducing animal ags’ greenhouse gas footprint is an urgent strategic step toward reversing climate change.

a vegan diet saves:
1100 gallons of water
45 lbs. of grain
30 sq. ft. of forested land
20 lbs. of CO2 equivalent
and 1 animal’s life!

In order to strengthen 350Marin’s broader mission to end the urgent climate crisis threatening life on our planet, the 350Marin Climate-Diet Team works to raise awareness of animal agriculture as a leading driver of climate change, and the importance of acting to quickly decrease its destructive greenhouse gas.

We invite everyone who is interested in this topic to join with us to:

  • present information about the ecological and social justice consequences of animal agriculture
  • educate about the environmental benefits of a plant-based diet
  • promote sustainable plant-based food production
  • engage in visionary and direct action

Climate-Diet Connections – What Others Say

The Guardian Newspaper, UK
UN urges global move to meat and dairy-free diet
“Lesser consumption of animal products is necessary to save the world from the worst impacts of climate change.”

Chalmers University of Technology, Sweden
The importance of reduced meat and dairy consumption for meeting stringent climate change targets Targeting the fossil fuel industry alone is insufficient because “the agricultural emissions … may be too high. Thus we have to take action in both sectors.”

Chatham House: The Royal Institute of International Affairs
Left Unchecked, Western Diets Could Derail Climate Action
“If the energy sector is successfully decarbonized by 2050, our diets can make the difference between the two-degree scenario in which dangerous climate change is averted and the four-degree scenario described by the World Bank as one of ‘cataclysmic’ climate change.”

Oxford University
Dietary greenhouse gas emissions of meat-eaters, fish-eaters, vegetarians and vegans in the UK
“… dietary GHG emissions in self-selected meat-eaters are approximately twice as high as those in vegans.”

Science Illustrated
Will we be restricted to a vegetarian diet by 2050?
“Animal protein-rich food consumes five to 10 times more water than a vegetarian diet, and one third of the world’s arable land is used to grow crops to feed animals.”

National Geographic
Water Conservation Tips
“The water it takes to produce the average American diet alone—approximately 1,000 gallons per person per day—is more than the global average water footprint of 900 gallons per person per day for diet, household use, transportation, energy, and the consumption of material goods.”

Upcoming Events/Actions

Climate-Diet Team on Post Carbon Radio

Team members at the time, Emile Olson and Zhenya Spake, were interviewed on KWMR‘s Post-Carbon Radio program on June 22, 2015. You can listen to the podcast, “Agriculture and Climate Change”  HERE.

Post-Carbon Radio covers the climate crisis from a range of perspectives centered on Northern California. Climate change is the ultimate inter-related issue, so the show includes news and perspectives on clean and dirty energy, the economy, social justice, and even war and peace by featuring people, movements and new ideas about climate change from around the world and in West Marin County.
