What did you learn about dietary choices from using the footprint calculator? Now imagine that you could translate what you learned into an effective societal policy on food- what would it be? And how would this policy effect the need to alleviate world hunger?
925 million people on earth do not have enough to eat according to the FAO [Food and Agricultural Organization]. That's almost 1 in 7 inhabitants of our planet!

Harmful Effects of Eating Meat
Although I am not completely sure that becoming a vegetarian can save a lot of water, it can help the environment in other ways. It can help reduce carbon emission from factory farms. A lot of Cabon dioxide is emitted from factory farms along with other harmful gases. We also feed so much grain to animals when it really should go to people. in the US about 70% of grain grown is given to animals. Finally, About 30% of the Earth's land mass is used for raising animals for food alone and deforestation is occurring to clear land for animal pastures.
