Perform economic, environmental and social benefits analysis of using plant based diet in airports and flights. Industrial meat, poultry, and dairy production has a huge footprint of resource consumption--energy, water, and land. As a result the practice produces air, water and land pollution. The practice also causes human health related deceases. A triple Bottom Line analysis of low carbon plant based food usage will be helpful to encourage the change and ultimately eliminate the use of industrial food sources. With the expected population rise and climate change, this is an important sustainability initiative.
