# Polar Ecosystems Compared

Compare Arctic and Antarctic ecosystems — the Arctic has both terrestrial (tundra) and marine ecosystems supporting large land mammals and indigenous human communities, while the Antarctic is almost entirely marine-based with virtually no land plants or mammals; both regions have short, intense food chains anchored by phytoplankton and krill, and both are disproportionately affected by climate change and human activity
