Dining on 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.

Scientists at the University of Helsinki have produced a study saying there'd be big environmental benefits if those who can move their diets towards novel foodstuffs -- grown in labs, derived from algae, fungi and powdered seaweed - did so, rather than consuming dead animals or animal by-products.

Rachel Mazac, one of the authors behind the report, told Newshour's Tim Franks more about the investigation and the impact switching to food like cultured meats and milk could have.
