Once a week, is not too much at all
Each year, millions of animals are slaughtered on factory farms for human consumption. Factory farming is a leading cause of global warming because it increases the levels of gases such as carbon dioxide, methane, and nitrous oxide. Because meat is produced on factory farms, those that consume meat on a daily basis, or have a diet that depends heavily on meat and poultry contribute greatly to the amounts of greenhouse gases in the atmosphere. Adopting a vegetarian or vegan diet, or even just opting to go vegetarian once a week, which can be as easy as choosing a salad for lunch, can decrease the levels of greenhouse gases, in the atmosphere.
