  1. Climate chat: How to cook a planet …..or not.

  2. Climate chat: Food & Climate

  3. US Greenhouse Gas Emissions

  4. World Greenhouse Gas Sources IPCC 2007

  5. Effects of GHG on Agriculture • Crops • While CO2 & higher temps may increase yields… • Overall lower crop yields • Heat waves • Drought • Flooding • Extreme weather • Increased threats from parasites and diseases • Decreases productivity

  6. Vicious Circle Agriculture produces greenhouse gasses, which leads to global warming More land used for agriculture leads to more global warming. Global warming impedes food production leading to poorer growing conditions. Because of poorer growing conditions, more agricultural land is needed to farm Because of global warming, we will need more land to produce the same amount of food.

  7. Food Production • Accounts for 19 – 29% of greenhouse gasses • 80% of agricultural emissions are from animal production, including animal methane emissions (14-18% of total GHGs – compare to all transportation @ 13%) • Most deforestation is due to agriculture (livestock production accounts for 70% of it) • Food production requires energy for: • Soil management, fertilization, pest/herb-icides • Farm machinery/irrigation • Transportation • Agriculture is responsible for most methane and nitrous oxide emissions

  8. CO2 Emissions by food Source: Environmental Working Group

  9. You think the human population is increasing? The world’s meat supply is growing faster than the population. As we become wealthier, we consume more meat. Source: UN Food & Agriculture Organization

  10. To put it in perspective… It takes the energy equivalent to 31 KWH to produce one pound of beef The average California home uses 22 KWH of electricity per day to run their home. To compare: 1.4 days of electricity for your home 1 pound of beef =

  11. 5,000 gallons of water are required to produce one pound of beef The same as filling 10 fifty-gallon water barrels. Average San Diego family uses 350 gallons of water per day. One pound of beef, 14 days of water.

  12. Is beef the hummer of the food world?

  13. Is meat is like a food factory in reverse? Start with a large of amount of animal food Animal feed fed to livestock End result, very little food produced Meat, a bad investment: 15 units of feed to produce one unit of food

  14. Food Waste • 40% of food produced is wasted. • For the average US household of four, food waste translates to $1,350 - $2,275 per year • Additional cost (and GHG’s) in disposing of food in landfills: landfill costs, refuse pickup • Rotting food creates methane gas, a GHG 21 times more potent than CO2

  15. Where food waste occurs

  16. Multiplied losses • Because of waste, more food than is consumed must be produced • On average 16.7 pounds of food must be produced for 10 pounds of food to be consumed (40% waste) • Consume less, less waste.

  17. Other Areas of Food Emissions • 24% - Packaging and Processing • 90% of food eaten is processed • 12% - Transportation • Food Miles – Railway 10X more efficient than trucking. Shipping is most efficient. Air is least efficient. • Local food can be lower GHG, but not necessarily as food grown closer to home can be less sustainably grown, transportation is often a small % of overall energy, and freight can be very efficient. • Organic – potential to be lower-GHG • Other: transportation to and from food store, cooking, refrigeration, etc.

  18. Climate chat: Discussion Food & Climate

  19. How can we lower our carbon “food-print”?

  20. Eat less(Stop eating at 80% full)

  21. 2. Eat less meat Eat less meat in whatever way works for you. Cut back in each meal, eat lower on the food chain (chicken v. beef), or try Weekday vegetarian or Meatless Mondays.

  22. Just eat healthy?

  23. Stir-Fry: 3 ways Veggie Beef Chicken

  24. 6 lbs 31 lbs 11 lbs

  25. 3. Eat fewer processed and packaged foods, fewer “empty calories”

  26. 4. Increase efficiency and decrease waste

  27. Shopping thestoryofstuffwater Think about where your food comes from… • Bring a list so you buy only what you need. • Is the food unprocessed? • Is it un- or minimally packaged? • Is it seasonal? • Is food organic? • Is it nutritious? • How was it transported? • Was it grown sustainably? • How far is the store/market?

  28. In the home • Plan your meals • Eat your leftovers • Don’t let food expire • Cook multiple dishes in the oven simultaneously • Cut down on frozen foods • Keep your Refrigerator/Freezer full • Conserve water • Eat all of the food (e.g., make soup from scraps) • Eat at home more

  29. Home Grown • Home Gardens: less water than a lawn; can control oil-based inputs (fertilizer, pesticides) • Fruit Trees: low-water, appropriate for climate • Grow in the home: sprouting, hydroponics, potted food plants • Chickens: Produce eggs; consume food scraps • Also: everyone can compost

  30. BONUS! A low-GHG diet is Healthier for you & your family Better for the environment Kinder to animals Delicious

  31. Climate chat: Discussion, What you can do

  32. What’s Next? How each of us can make a difference… Make changes in our own lives and homes Share your knowledge and your passion on climate change with family, friends, co-workers, neighbors Let your elected officials and the media know that climate change requires immediate action Volunteer with an organization working on climate change

  33. What’s SanDiego350.org? We work to increase awareness of climate change and advocate for reducing greenhouse gas emissions. All-volunteer San Diego organization loosely affiliated with 350.org Started up in 2011 after successful 350.org “Moving Planet” event in Balboa Park We believe that everyone, regardless of their skills or time available, has a role in this movement.

  35. Advocacy and lobbying for stronger climate policies Photos: Lobbying members of Congress in summer, 2012 to eliminate fossil fuel subsidies (Susan Davis, above, Duncan Hunter, right)

  36. Organizing rallies and protests to bring attention to the issues Photos: Keystone pipeline rally Feb 2013; protest of SDG&E’s proposed solar tax Jan 2012

  37. We hope you’ll join us! Monthly newsletter Monthly general membership meetings third Tuesdays 6:45-8:15 pm (next is on March 19th at St. Paul’s Cathedral, 6th and Nutmeg) Teams

  38. THANK YOU!! • World Resources Simulation Center • Ocean Beach People’s Co-op • Sierra Club San Diego • YOU
