I would prefer people would go vegan, but this is a great first step. Go Meatless on Mondays:
If we all just commit to one day a week without eating meat, the effect will be great over the course of the year:
Our greenhouse gas emission reductions equal US switching from a car with average fuel efficiency (that’s about 22 mpg for the entire fleet) to a high efficiency car such as the Toyota Prius (50 mpg).
We will save about 1 ton of water, enough to fill up the bathtub 22 times per week
If everyone in the US did this, we’d collectively save about 12 billion gallons of gasoline
