While your burger might seem innocent, the shocking reality is that the land, water, and emissions used to produce it are quietly fueling a global environmental crisis, a fact underscored by statistics showing animal agriculture accounts for 14.5% of all human-caused greenhouse gases, uses 77% of farmland for just 18% of our calories, and consumes thousands of liters of water for a single serving.
