It's easy! Pledge to go meat-free one day a week in 2014. Then, pledge to go meat-free two days a week in 2015, three days a week in 2016, etc. By 2020 you will be 100% meat-free, and all the land used to grow food for the cows, pigs, and chickens you would have eaten will be available to grow food that will feed many, many more hungry people.
