Veganism is a philosophy and lifestyle that seeks to avoid exploiting and causing harm to animals. The Veganuary campaign encourages people to try going vegan for the month of January, with over 3,200 people committing to participate in 2014. Veganism not only helps reduce animal suffering and benefits the environment, but also improves personal health as vegans consume more fruits and vegetables. However, vegans need to ensure they get enough vitamin B12, which is found in animal products, through supplements or fortified foods. The meat industry has a large environmental impact through greenhouse gas emissions and water use.
