How much of the earth's land surface is covered with grasslands?

Grasslands cover approximately 20 to 40 percent of the Earth's land surface, making this the most accurate choice. This classification includes various types of grassland ecosystems such as prairies, savannas, and steppes, which can be found on every continent except Antarctica. Grasslands play a crucial role in the Earth's ecology, contributing to biodiversity, carbon storage, and soil health.

Understanding the extent of grasslands is important for conservation efforts and land management practices, as these ecosystems are often threatened by agricultural development, urbanization, and climate change. The significance of this range emphasizes the need for effective management strategies to protect these vital landscapes and their associated wildlife.
