Imagine an overgrown subway tunnel where vibrant vines snake along the rusting tracks, their emerald leaves bursting with life. Rays of sunlight filter through cracked ceilings, illuminating a rich tapestry of wildflowers and ferns carpeting the ground. Birds flit between the remnants of forgotten trains, while small animals peek out from their hidden nests. This once-bustling hub now echoes with the symphony of nature, reclaiming its territory.
