What percentage of the Earth's surface is covered in range?

The correct answer, which states that 51% of the Earth's surface is covered in range, reflects the significant portion of land that is classified as rangeland. Rangelands are critical ecosystems that provide habitat for wildlife, grazing for livestock, and serve important roles in soil conservation and carbon sequestration. This percentage indicates the vast expanses of grasslands, shrublands, and savannas that contribute to global biodiversity and ecological health.

Understanding the scope of rangeland is essential for appreciating its importance in sustainable land management and conservation efforts. This knowledge also emphasizes the need for responsible practices to maintain these vital ecosystems amidst challenges such as climate change, land use changes, and overgrazing.

While the other percentages represent alternative land cover types, they do not accurately convey the extent to which range encompasses the Earth's surface compared to rangeland's documented contribution.
