Food production is responsible for one-quarter of the world's greenhouse gas emissions. Therefore it seems obvious that if humans stopped eating food we would stop producing a lot of green house gases. Obviously we can't all stop eating. None of us can stop eating. But a lot of us could eat less occasionally.
A growing trend in developed nations over the last decade is the use of fasting to improve health. The theories, backed by quite a bit of science, imply that an occasional fast helps to jump start our body to burn energy differently producing positive effects.
Some fasting trends ask a person to simply skip a single meal. Many ask a person to skip all food one day a week, Fasting can be good for you, but it is also good in our fight against global warming.
I'm sure some people, and I will call them out rightly as "selfish", think that the effect of one person skipping a meal is insignificant in our battle against globabl warming. They use this opinion to justify why they are not going to make a single change in their life to combat global warming, and also because the dogma they espouse insures that global warming isn't real, or won't be all that bad, or that "scientists" will magically discover a fix to it; thus eliminating their need to take any action that may inconvenience themselves or have the appearance of replacing their own self-interest with a desire to do good for the world.
The truth is that the only way we can combat global warming is throught to summed efforts of billions of apparently trivial actions. If humans could simply each give a little, we could slow and possibly stop global warming.
If every person in developed nations, with access to plentiful food, gave up one meal a week, it would slow down global warming measurably. Possibly by as much as one percent. If those same people simply skipped eating meat for six meals a week, we could reduce global warming by two percent.
Fasting not only provides health benefits for most people, but helps our fight against global warming.
I am sure many food industries will fight against the idea of large numbers of people fasting, despite the health and environmental benefits because they might lose a few dollars. But we shouldn't let the food industries provide us guidance about what is best for our health and environment when they profit so greatly from harvesting our environment to overfeed us to the detriment of our health.

Fasting is not for everyone, but it is for most.
