Rewrite the essay to be more clear and understable while being high college level. The goal of this section of the essay is to explore climate change in the background and how it is a pressing issue and needs to be addressed. the literary review should focus on the 3 large causes of unsustainability in the food servcie industry: use of agriculture, food waste, and unsustainble ingridents. I would like ideas to be well developed and thought out in an academic way.
