Commentary: Veganism isn’t the answer
Writing in the Guardian, Isabella Tree of Knepp Castle Estate argues that vegan diets ignore the potential of wildlife-friendly livestock grazing methods. Tree claims that not using anti-worming agents or antibiotics allows cow dung to feed various soil organisms, contributing to soil restoration and wildlife diversity.
Although Tree says, “There’s no question we should all be eating far less meat, and calls for an end to high-carbon, polluting, unethical, intensive forms of grain-fed meat production are commendable”, she says that unless vegan products come from organic, no-dig systems, then they are contributing to soil destruction, depriving wildlife of habitat and contributing to climate change through ploughing.
George Monbiot, replying, argues that this form of livestock rearing would produce much less food per hectare of land than the production of vegan foods - and that, therefore, a vegan diet could allow some farmland to be returned to its natural form.

Europe is the world's second-smallest continent by surface area, covering just over 10 million square kilometres or 6.8% of the global land area, but it is the third-most populous continent after Asia and Africa, with a population of around 740 million people or about 11% of the world's population. Its climate is heavily affected by warm Atlantic currents that temper winters and summers on much of the continent. In the European Union, farmers represent only 4.7% of the working population, yet manage nearly half of its land area.
