Animal agriculture is responsible for the suffering and slaughter of trillions of animals each and every year around the globe. In addition to that the detrimental effects on human health and the environment are undeniable.
Human health: Research reveals that following this type of diet will lower your risks of heart disease, high blood pressure, Type 2 diabetes, digestive disease, cancer and obesity. Studies also show that a plant-based diet can help to lower body weight and reduce your LDL cholesterol.
“No matter when you start, a diet that is focused on plant foods will help you work toward the prevention of many illnesses and feeling better overall,” – Julia Zumpano, RD, LD 
Environmental impact: “The destructive impact of animal agriculture on our environment far exceeds that of any other technology on Earth…The greenhouse gas footprint of animal agriculture rivals that that of every car, truck, bus, ship, airplane, and rocket ship combined” 
When you accept that a plant based diet not only reduces the suffering of animals but is also better for your own health and that of the environment, how can anything other than adopting a plant based diet be a morally acceptable choice.
