Here are the slides from the presentation on Food and Climate at the WMYCS 2019! I'm also including links to the data I cited throughout the slides in case you want to learn more, as well as info on how you can ask the government to include sustainability in the food guidelines.
Resources from the talk:
Intergovernmental Panel on Climate Change Special Report on Land (SRCCL)
Summary of agricultural part of the report from ICN, from Nature, and from WRI
Land use map of US
Summary of a great study on environmental impacts of food. Research was by Poore and Nemecek.
Link to the study from slide 11 on the emissions of different types of food.
Data on food miles and emissions.
Food Empowerment Project- lots of great info on climate, worker's rights, growing food, etc.
InsideClimate coverage of food issues, and their Harvesting Peril series on farms and climate (I didn't have time to cover this in the talk, but it has interesting info).
In the US, food guidelines aren't required to take sustainability into account, even though the panel of experts from the last round of updates to the guidelines proposed that it should. The next round of guidelines is now being formulated and the public is allowed to comment on what they want to see changed. Submitting a public comment is a way to make your voice heard even if you can't vote yet.
Union of Concerned Scientists explanation of dietary guidelines in the US and their informational page on food and sustainability.
Here is a research study (cited in the slides) showing how not including sustainability and climate impacts in dietary guidelines makes it very hard for us to meet the Paris Agreement goals.
