Coastal Paper-bark

Coastal paper-bark (Melaleuca halmaturorum) is a shrub or small tree in the family Myrtaceae, native to southern Australia, particularly South Australia and southwestern Victoria. It grows in coastal and inland saline environments, including salt marshes, samphire flats, brackish wetlands, and the margins of ephemeral lakes. The species is highly salt-tolerant, often forming dense thickets that provide critical habitat for waterbirds, including migratory shorebirds. Its distinctive bark peels in papery layers, a hallmark of the Melaleuca genus, while small white bottlebrush-like flowers attract native insects and honeyeaters. Reaching up to 5 metres in height, it can persist through seasonal flooding and drought cycles. Coastal paper-bark plays an important ecological role in stabilising saline soils, reducing erosion along shorelines, and filtering nutrients from adjacent agricultural land. The IUCN lists it as Least Concern, reflecting its wide distribution across southern Australia. It is also cultivated as an ornamental in gardens tolerant of poor drainage and is considered valuable for ecological restoration in degraded coastal wetlands.

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.
