In this project we will find the fact about vegetables and meat by comparing between vegetarian diet and omnivore diet in three aspects: nutrients, lifestyle and effects. We will study about health problems that may be caused by vegetables and meat. We must explore and interview people to keep the information about vegetarian aspects and non-vegetarian aspects. And we must study about people’s lifestyle of how they choose their diet. Eventually, the result of this research will answer if it is a good choice to consume a vegetarian diet?
