Nowadays vegetarianism is a "fashion" or a trend, meaning that more and more people are vegetarians. Vegetarianism as defined by The World Book Dictionary (1989) is " The practice or principle of eating only vegetable foods and refraining from eating meat, fish, or other animal products". Therefore, limits the nutrition of plant origin. But like everything we found different degrees of vegetarianism.

For example, about 0.75 L of water is required for the production of each gram of dry soybeans, while for each gram of dry meat weight an average of 20 L of water is required, being 26 times greater. Another aspect to consider is that animal husbandry contributes to soil degradation and many areas dedicated to extensive livestock are over exploited. Thus, meat consumption contributes to soil degradation by compaction and erosion. (Sabaté J. Religion, diet and research. British Journal of Nutrition. 2004). On the one hand, according to the United Nations Food and Agriculture Organization (FAO), the meat industry is one of the most damaging to the planet. According to a new report, livestock accounts for 18% of greenhouse gas emissions. Livestock accounts for 65% of nitrous oxide emissions and this has almost 300 times the global warming effect of carbon dioxide. On the other hand, according to researchers at Carnegie Mellon University in Pittsburgh, United States, say that vegetarian diets are more harmful to the environment than high-calorie diets. The study focused on measuring the amount of water spent, the amount of energy and the emersion of gases. It was observed that diets considered to be healthy cause an energy consumption of 38% of water use (10%) and greenhouse gas emissions
