Vegetarian diets not always the most climate-friendly, researchers say

ROME, Sept 17 (Thomson Reuters Foundation) - It may be possible to help tackle climate change while still munching on the occasional bacon sandwich or slurping a few oysters, a new study suggested on Tuesday.

Scientists found that diets in which meat, fish or dairy products were consumed only once a day would leave less of a footprint on climate change and water supplies than a vegetarian diet including milk and eggs, in 95% of countries they analysed.

That is partly because raising dairy cows for milk, butter and cheese requires large amounts of energy and land, as well as fertilisers and pesticides to grow fodder, emitting greenhouse gases that are heating up the planet, the study said.

Diets that contain insects, small fish and molluscs, meanwhile, have as similarly small an environmental impact as plant-based vegan diets but are generally more nutritious, said researchers at the Johns Hopkins Center for a Livable Future.
