There are 1.5 billion cows on the planet that produce almost 8% of the world’s carbon emissions. In addition to methane from the cows themselves, growing and feeding cows is a major cause of deforestation, leading to habitat loss and species extinction. Eating too much red meat also creates health problems for humans due to high levels of cholesterol and saturated fat. You don’t have to be a vegetarian or a vegan to eat sustainably. Start small and add more fruits and vegetables to your diet. For your health and the health of the planet.
