• Scientists divide the planet into several major ecozones based on climate and wildlife.
• The Palearctic ecozone includes much of Europe and northern Asia.
• Each ecozone has adapted species that thrive in its unique environmental conditions.
• Conservation efforts often focus on protecting entire ecozones rather than individual species.
• The boundaries between ecozones are not always sharply defined in nature.
