Earth Running Out Of Plants??

According to satellite data, the earth produces 53.6 petagrams of plants a year. No, a petagram isn't a letter from Josh Hutcherson, it's about 2.2 trillion lbs.
Of that, humans use about 40%, or about 24 billion tons!
That seems like a lot of salad, but it might not be enough!
