The Veganuary campaign has grown significantly since launching in 2014, with over 59,500 people participating in 2017, more than double the number from the previous year. Adopting a vegan diet can provide health benefits by reducing risks of diseases like heart disease and diabetes. It also helps the environment by reducing greenhouse gas emissions and water usage associated with industrial animal agriculture. While vegans must ensure they obtain key nutrients like vitamin B12, a vegan diet when planned properly can meet all nutritional needs.
