Switching to futuristic foods will reduce carbon emissions and save land and water, a study suggests.
They say switching meat, dairy and other animal products for alternative foods could reduce these impacts by more than 80%, while providing a more complete range of essential nutrients than a purely vegetarian or vegan diet.But they also found that relatively low-tech solutions, such as cutting down on meat and eating more vegetables, had a similar impact on the planet.
But she said there were "similar savings in impacts in a vegan diet". And in a diet with a 75% reduction in animal-sourced foods, "you can have an approximately 75% reduction across all of your impacts". Dr Asaf Tzachor of the University of Cambridge, who was not part of the research team, said while these are "promising" findings, the unwillingness of consumers to shift their diets might "postpone, or indeed prevent, this much-needed transition".
