In some countries, meat is expensive and seen as a delicacy. In countries such as the U.S., meat is available at fast-food chains at a low cost, making it easier to consume more meat. Eating more meat raises cholesterol levels in the body, builds up plaque in blood vessels, and increases risk of heart attack and stroke. Raising animals contributes to deforestation and methane production. Deforestation contributes to the displacement of indigenous people. All of these practices directly contribute to climate change, which impacts human health in many ways such as air pollution, heat waves, and sea level rise.
