Bramble Cay melomys: Extinct!

The Bramble Cay melomys (Melomys rubicola) was officially recognized as the world's first mammal to have gone extinct directly due to the consequences of human-induced Climate change. This small rodent, also known as the mosaic-tailed rat, lived exclusively on Bramble Cay, a tiny island in the eastern Torres Strait near Australia, which was barely 10 feet above sea level. Life for the Bramble Cay melomyses seemed straightforward as they resided within the shelter of leafy shrubs, feeding on them and scurrying across the sandy surroundings of their secluded home. Their routine was occasionally interrupted by human visitors, birds, or occasional storms.

However, their population decline was swift and alarming. Scientific reports dating back to 1978 documented the presence of several hundred melomyses. Yet, by 1998, a survey commissioned by the Australian government recorded fewer than 100 of these rodents, signaling a significant and rapid reduction in their numbers over time. Scientists reported the disappearance of this species from its habitat due to rising sea levels, erosion, and habitat loss caused by climate change. The Cay was found to have experienced a severe loss of more than 90% of its plant life since 2004, largely caused by the flooding of seawater. This sharp decrease in vegetation undoubtedly played a major role in the extinction of the Bramble Cay melomys by significantly reducing their food sources and protective shelter. The last confirmed sighting of the Bramble Cay melomys was in 2009.

The loss of the Bramble Cay melomys highlights the vulnerability of certain species to the rapid environmental changes induced by human activities, especially in delicate ecosystems like small islands that are highly susceptible to rising sea levels and extreme weather events. Whether it is a little mammal inhabiting an island or a heavenly beast that walks Mother Earth- lives of so many precious animals are threatened and vulnerable at varied extents, all because of our actions. It is predicted that by 2100 more than half the world's species may face extinction...Yet, there is hope! There is a chance to rectify our actions, if we pledge to all join hands and start right now!
