Managed correctly, cows can play a role in restoring healthy soils. Cows are ruminants and have a unique digestive system that allows them to break down and digest tough plant material such as grasses and forages. By grazing on these plants, cows can help to control invasive species and promote the growth of native plants, which can lead to an increase in biodiversity. Additionally, cows can help to aerate the soil and distribute seeds through their manure, which can lead to an increase in plant growth.

Regenerative and holistic management practices, such as rotational grazing, can be used to mimic the natural grazing patterns of wild herds, which can help to improve soil health and sequester carbon in the soil. These practices can also help to improve water retention in the soil and reduce erosion, which can lead to an overall increase in soil health and fertility. Additionally, regenerative agricultural practices can also improve the well-being of the cows and other livestock, by providing them with a diverse diet, and reducing the need for feed supplements, and veterinary inputs.

It's important to note that any solution involving cows and other livestock should prioritize the well-being of animals, and ensure that the land is able to support the number of animals, so that the land is not overstocked and overgrazed, leading to destruction of natural habitats and biodiversity.
