- How a mere 12% of Americans eat half the nation’s beef, creating significant health and environmental impacts. Those 12% – most likely to be men or people between the ages of 50 and 65 – eat what researchers called a disproportionate amount of beef on a given day. https://news.tulane.edu/pr/how-mere-12-americans-eat-half-nation%E2%80%99s-beef-creating-significant-health-and-environmental 4 comments environment
- A mere 12% of Americans eat half the nation’s beef, creating significant health and environmental impacts. The global food system emits a third of all greenhouse gases produced by human activity. The beef industry produces 8-10 times more emissions than chicken, and over 50 times more than beans. https://news.tulane.edu/pr/how-mere-12-americans-eat-half-nation%E2%80%99s-beef-creating-significant-health-and-environmental 1969 comments science
