My Favourite Biome

There are many biomes on the earth, like grasslands, forests, deserts, taigas and tundras.  My favourite biome is tundra.  It is covered in snow and ice.  It has very long history.  Mammoth lived there before, and narwhals, polar bears and seals are living there now.   Their fats are thick and can keep them warm.  I like tundra biomes very much, because it has many interesting animals.
