Common Blue-sow-thistle

The common blue sow-thistle (<em>Lactuca macrophylla</em>) is a plant species native to Europe, with documented occurrences in the Czech Republic, Denmark, France, Iceland, and Norway. This species typically inhabits diverse terrestrial environments, adapting to a range of ecological conditions across its European range. As a member of the family Asteraceae, it often grows in disturbed habitats, roadsides, and woodland edges throughout its native range. The common blue sow-thistle has not been formally assessed on the IUCN Red List, so its global conservation status remains unevaluated at this time. This species typically forms part of the understory vegetation in temperate ecosystems. Its broad distribution across northern and central Europe suggests a degree of ecological resilience and adaptability to varying climatic conditions. Biological traits of this species remain poorly documented in the scientific literature.

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.
