Producing nearly 15% of the Earth’s greenhouse gas emissions, the meat industry is one of the top contributors to climate change. Slowly, very slowly, movements like Meatless Mondays and Vegan Before 6 have demonstrated the value, and deliciousness, of adopting a vegan diet, but a carnivorous diet is still seen as evidence of prosperity.
In 2009, researchers at the Netherlands Environmental Assessment Agency calculated that global veganism would reduce agriculture-related carbon emissions by nearly 17%, methane emissions by 24%, and nitrous oxide emissions by 21% by 2050.
The researchers discovered that worldwide veganism, or even just worldwide vegetarianism, would achieve gains at a much lower cost that an energy intervention, like carbon taxes, for instance.
The study demonstrated tremendous value of a vegan or vegetarian diet in staving off climate change, but there are so many other benefits as well. Antibiotic resistance stemming from the meat consumed that has been pumped full of antibiotics would plummet. Pollution rates would drop significantly as factory farms, the biggest polluters in the meat industry, became a thing of the past. General human health and well-being would rise from a plant-based diet free from cholesterol and pharmaceuticals.
By 2050, the global population is predicted to reach a staggering 9 BILLION people.
