Christplant

The Christ plant (Euphorbia milii) is a woody succulent shrub in the family Euphorbiaceae, native to Madagascar. It is one of the most popular ornamental succulents globally, widely cultivated for its bright floral bracts — actually modified leaves surrounding small, inconspicuous true flowers — which appear in red, pink, yellow, or white in wild and cultivated forms. The stems are densely covered with stout spines, contributing to another common name, crown of thorns, derived from the legend that Jesus's crown of thorns was made from this species, though the plant is native to Madagascar and this association is symbolic rather than historical. Euphorbia milii is extremely drought-tolerant and thrives in warm, dry conditions with minimal watering, making it well suited to indoor cultivation and tropical to subtropical outdoor gardens. Like all Euphorbia species, it produces a milky latex sap that is irritating to skin and toxic if ingested, requiring careful handling. The species is a member of one of the largest and most diverse plant genera, Euphorbia, which spans succulents, shrubs, and trees across multiple continents. In Madagascar, wild populations are affected by ongoing deforestation, though the species is widespread in cultivation globally.

Polar bear

地球上で最大の陸上肉食動物であるホッキョクグマは700kgを超えることがあり、カナダからロシアまでの北極海氷域全体に分布する。ワモンアザラシとヒゲアザラシを狩るために海氷に依存する高度に特化した海洋哺乳類である。広大な距離を泳ぐことができる優れた泳者でもある。脆弱種に指定されており、気候変動による急激な北極海氷の消失で個体群が深刻な圧力を受けている。
