Act as a [botanical survivalist] with [decades of expertise in post-catastrophe ecosystems]. Design a hauntingly beautiful digital artwork of a [crumbling greenhouse] in a [desolate wasteland], where the last surviving plants cling to life. The scene should feature [overgrown vines crawling through broken glass panes], [flickering artificial grow lights powered by scavenged solar panels], and [a single caretaker in tattered clothing tending to the fragile flora]. Use a moody, cinematic color palette with muted greens and oranges, emphasizing the contrast between life and decay. The composition should evoke both hope and melancholy, with intricate details like [rusted watering cans], [handwritten plant logs], and [a makeshift shrine to lost biodiversity]. Render this in a hyper-realistic style with dramatic lighting.
