Can we become more eco-friendly by reducing meat consumption? Nowadays, vegetarian and vegan diets are more and more popular in the mass media, such as the press or television, and in several social networks. In the past years , this point has remained for majority of the population, altogether with which may be the causes to become a vegetarian/vegan and which are the consequences that can be carried out. In the first place, people may think changing their diets won't have any impact in the enviroment. In addition, probably it is thought that the way farms are raising the animals is more sophisticated , and animal welfare is taken more into account than years ago. However, several studies conducted by oficcial european organizacions, such as the committe FAO/OMS, had announced the large impact of the livestock farming in our planet. For example, pig slurry filtrates on the soil and contaminates ground water. What's more, to feed farm animals, it is necessary to use high amounts of soil to produce enough animal food, with the resulting water expenditure. To sum up, I think we have enough reasons to reduce meat consumption, since there are some official studies that points out all the negative consequences that livestock farming produces in the enviroment.
