The livestock industry is responsible for a staggering amount of greenhouse gas emissions, with a single beef burger taking up to 450 gallons of water to produce.

Conor Lennon from UN News went along to see how the new generation of meat-free meals are going down with the notoriously hard-to-please burger-loving public of New York City.
