"It's impossible to''go green' without going vegan', says Whichello, a vegetarian since birth and vegan for the past six months.
"By simply going vegan, we can help protect the Earth, our health and countless animals and can also save nearly 1 million litres of water a year."
A recent United Nations report found that the meat industry is "one of the top two or three most significant contributors to the most serious environmental problems, at every scale from local to global."
Among these environmental problems is freshwater scarcity, and the report calls the livestock sector "a key player in increasing water use" and "probably the largest sectoral source of water pollution."
On average, it takes one-third more water and land to produce animal-based foods than plant-based ones – in part because of the extra crops needed to feed farmed animals.
Also, in addition to causing animal suffering on a massive scale, eating meat, eggs and dairy products has been linked to heart disease, cancer, strokes, diabetes and obesity.
Like humans, animals are capable of suffering and have interests in leading their own lives; therefore, they are not ours to use – for food, clothing, entertainment, experimentation or any other reason.
PETA and its affiliates around the world educate policymakers and the public about cruelty to animals and promote an understanding of the right of all animals to be treated with respect.
PETA works through public education, research, legislation, special events, celebrity involvement and protest campaigns.
