to make more people vegetarian

You don't necessarily need people to go full vegetarian. Just eating less meat is a much easier sell. If 2 people eat 1/2 as much meat as they otherwise would, that's just as good as 1 person going full vegetarian.

The type of meat also matters. Beef is much higher in greenhouse gas emissions than any other type of meat. So if you just switch beef for, say, chicken or pork, you're already doing a lot better.

While switching to plant based food is an obvious course of action which would have drastic benefits, several other methods exist by which agricultural emissions. These include:

• Livestock diet changes to reduce methane production
• More accurate fertilizer application to reduce nitrous oxide production
• Draining rice paddies to reduce production of methane by anaerobic microbes
• No till farming to allow more carbon to be stored in the soil
• Farm equipment electrification
• Crops bred for higher yield or lower resource usage
