Common Yew

<em>Taxus baccata</em>, the common yew or English yew, is a slow-growing evergreen conifer in the family Taxaceae, native to western, central, and southern Europe, northwest Africa, and southwest Asia. It is one of the longest-lived trees in the Northern Hemisphere, with some individuals estimated to be several thousand years old. The species grows in a variety of habitats including mixed deciduous woodland, calcareous scrub, chalk downlands, and rocky slopes, often as an understorey or emergent tree. Yews are dioecious; female trees produce distinctive bright red fleshy arils surrounding a single hard seed, the only non-toxic part of the plant. All other parts, including the leaves, bark, and seeds, contain highly toxic taxine alkaloids that are dangerous to humans and most animals. Average lifespan can exceed 1,000 years under suitable conditions. <em>Taxus baccata</em> is ecologically important as dense, long-lived woodland habitat and as food for birds that disperse its seeds. Medicinally, taxol derived from yew bark is used in cancer treatment. The species is assessed as Vulnerable due to habitat degradation, overgrazing, and historic overexploitation across parts of its native range, though it remains locally common.

Polar bear

지구상에서 가장 큰 육상 육식동물인 북극곰은 700kg을 넘을 수 있으며 캐나다에서 러시아까지 북극 해빙 전역에 분포한다. 고리 물범과 수염 물범을 사냥하기 위해 해빙에 의존하는 고도로 특수화된 해양 포유류이다. 광활한 거리를 헤엄쳐 다닐 수 있는 뛰어난 수영 실력을 가지고 있다. 취약종으로 등재되어 있으며, 기후 변화로 인한 급격한 북극 해빙 감소로 심각한 압력을 받고 있다.
