With a plant-based diet we would have more food to feed starving people, waters for droughts, and cleaner rivers and more natural habitats. That alone would be enough to feed each of the 60 million people who starve to death each year around the world. Half of the water used in the United States is dedicated to livestock production. Essentially, water that could be used to grow fruits, vegetables, and grains is now lost on livestock. A considerable amount of land is misappropriated for a meat-based diet.
Desertification leads to increased sediment loads in rivers, which harms wildlife.
