Eat less meat
Sir Paul McCartney (illustration) has been a vegetarian for many years. Together with his two daughters he is backing the “meat-free Monday” campaign, which encourages people to have one day a week without meat on the menu.
Meat production is generally more damaging for the climate than the production of fruit and vegetables because farm animals emit more methane and nitrous oxide, which are far more powerful greenhouse gases than CO2. In addition, the animals eat food that people could have eaten directly. If people cut down on meat consumption, land areas could be freed up for food cultivation. This is particularly important because we will need more food in future years to feed the growing global population. The UN fears that as many as 370 million people could starve by 2050.
Greenhouse gas emissions from Norwegian agriculture consist of about half methane and half nitrous oxide.
