Rainforests cover which percentage of the earth?

Rainforests cover about four to six percent of the Earth's surface, making six percent the most accurate response within the provided options. Rainforests are crucial ecosystems, accounting for a substantial amount of the Earth's biodiversity and playing vital roles in carbon sequestration, oxygen production, and water cycling. The figure of six percent reflects a generalized estimate that acknowledges the significant presence of tropical rainforests, which are the primary focus in such discussions.

While ten, eight, and four percent are numbers that might appear plausible, they either overestimate the coverage or fall short of the more commonly accepted averages for rainforest coverage on the planet. Understanding this percentage helps in appreciating biodiversity conservation efforts and the ecological significance of these vital ecosystems.
