A host of non-conventional foods are being developed with the aim of providing food rich in protein and other nutrients, while being gentle on the planet by using less water and land. 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. Dining on the likes of lab-grown meat or ground-up insects could lead to big savings in carbon emissions and water, as well as freeing up land for nature. Do you think that the meat is health for human consumption ?
