This public service announcement was produced by an organization called "Let's Act Now".  The goal of the clip is to raise awareness of the incredible amount of energy that is used in the process of growing meat.  And yes, the massive volume of greenhouse gases that are emitted by the livestock themselves!  According to a recent report from the United Nations Food and Agriculture Organization,  animal farming produces more greenhouse gases than all global transportation combined.

 I just can't give up my occasional burger or steak, but I've reduced my consumption for health, budgetary, and ecological purposes.  So while I'm not fully on board with the meatless diet that Let's Act Now advocates, their PSA is effective, provocative, and worth sharing.
