Range

Widely distributed across Africa (12 countries), Asia (7 countries), Europe (16 countries), North America (6 countries), Oceania and the Pacific (Australia, New Zealand), and South America (8 countries).

Polar bear

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and boreal forests and taiga, among 4 distinct biome types within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Found in Norway. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Chufa (Edible Variety)

Chufa, also known as Tiger Nut or Earth Almond (Cyperus esculentus), is a cosmopolitan sedge in the family Cyperaceae valued for the edible, starchy tubers produced on its underground stolons. Originating in Africa, it was cultivated by ancient Egyptians and has spread to virtually all inhabited continents, thriving in warm to temperate regions with sufficient moisture. In Spain, chufa is commercially grown in Valencia for the production of horchata de chufa, a traditional sweet, milky non-dairy beverage made from soaked and ground tubers. The plant grows 20–90 cm tall with triangular stems characteristic of sedges, producing dense, grass-like foliage and small umbrella-shaped floral clusters. The pea-sized tubers are high in starch, sugars, fat, and dietary fiber. While valued as a food crop in some regions, Cyperus esculentus is considered an invasive weed in many agricultural contexts, particularly in maize, soybean, and sugar cane fields worldwide, where its deeply buried tubers make eradication difficult. The species is listed as Not Evaluated by the IUCN. Its global distribution and weedy habits make population-level threats essentially irrelevant in the conventional conservation sense.

Polar bear

The largest land carnivore on Earth, polar bears can exceed 700 kg and are found across Arctic sea ice from Canada to Russia. Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.
