Recent opinion articles advocate eliminating meat from human diets, or using artificial meat substitutes, to fight climate change. However, many experts believe that grazing animals used for meat are the key to the future health of the most altered, destroyed and endangered ecosystems on earth: grasslands.
That makes plant-based diets potential ecological disasters.
Of the 1.9 billion acres in the lower 48 U.S. states, 788 million are grassland. Globally, grazing animals and grazing land ecosystems evolved together through mutual adaptation. Human history has demonstrated that improperly grazed grasses become unhealthy, and leaving grasslands alone actually degrades them, whereas properly grazed lands become healthier.
Grasslands provide vital “ecosystem services” by sequestering carbon underground in extensive root systems, using up carbon dioxide, producing oxygen, filtering and storing water, providing habitat for other important species, and when grazed, converting cellulose that we cannot digest into high-quality protein that we can digest.
