    Chef’s Table With Dan Barber: A Sustainable Food Systems Film Review
    This episode of Chef’s Table (found on Netflix) discussed the idea of cooking in the world that we live in today through the lens of Dan Barber, the head chef of the Blue Hill Restaurants in Hudson Valley, New York (Stone Hill Farm) and in New York City.

On one of the more productive occasions, I turned my rage into a letter to the CEO of Hilton. Due to the fact that my dad is a Hilton Honors member, I realized that Hilton hotels give out two complimentary plastic water bottles to each of their honors guests. Upon noticing this, I pointed the issue out to my dad and began one of my rants about single-use plastic, the horrors of Nestle, etcetera. My dad, as usual, stopped my rant and cleverly redirected my anger toward the idea of writing a letter to Hilton about the issue. Together we brainstormed about alternatives for the plastic water bottles, and after some thought and research, I finished writing this letter to the CEO of Hilton. more
