Humans must adopt vegetarian or vegan diets to stop climate change, UN report warns (veg group)

The world must turn towards healthy plant-based diets to stop climate change, a UN-backed report has warned.

Cows, pigs and other farm animals release huge amounts of methane into the atmosphere. While there is less methane in the atmosphere than other greenhouse gases, it is around 25 times more effective than carbon dioxide at trapping heat.

Raising livestock also means converting forests into agricultural land, meaning CO2-absorbing trees are being cut down, further adding to climate change. More trees are cut down to convert land for crop growing, as around a third of all grain produced in the world is used to feed animals raised for human consumption.

Factory farms and crop growing also requires massive amounts of water, with 542 litres of water being used to produce just a single chicken breast.

As well as this, the nitrogen-based fertiliser used on crops adds to nitrous oxide emissions. Nitrous oxide is around 300 times more effective at trapping heat in the atmosphere. These fertilisers can also end up in rivers, further adding to pollution.

Overall, studies have shown that going vegetarian can reduce your carbon emissions from food by half. Going vegan can reduce this further still.
