Quick takeaways
Meta's $10 billion project to construct a 40,000-kilometer subsea cable network aims to enhance global connectivity while reducing reliance on third-party networks.
If humans disappeared, ecosystems would rapidly reclaim urban environments, highlighting nature's resilience and the adaptability of wildlife without human interference.
Deep dives
Nature's Reclamation After Human Absence
If humans suddenly vanished, nature would start reclaiming urban spaces almost immediately. Within days, plants would push through cracks in sidewalks and roads, demonstrating the resilience of ecosystems. Researchers highlight that urban wildlife, already adapting to human environments, would thrive in the absence of people, as seen in Bulgaria's Tirkman region where former agricultural lands have reverted to vibrant wildlife habitats after population decline. Similarly, the Chernobyl exclusion zone illustrates how wildlife can flourish without human interference, revealing that human presence may be more disruptive than environmental hazards like radiation.
The Fate of Domestic Animals and Ecosystems
The absence of humans would significantly impact domestic animals, particularly dogs, which would need to adapt to survive in a changed world. While many stray dogs currently rely on human waste, experts suggest that medium and large breeds could establish new pack structures for survival. Additionally, the oceans would witness remarkable recoveries, as evidenced by humpback whales rebounding after a ban on commercial whaling, which underscores nature's capacity to heal without human activity. Over time, human structures would deteriorate and be enveloped by vegetation, paving the way for new ecosystems, although remnants of human influence, such as plastic pollution, would remain.

Exploring Global Connectivity and the Genetics of Orange Cats
In today's episode of Discover Daily, we begin with news that Meta is embarking on an ambitious $10 billion project to construct a 40,000-kilometer subsea cable network. Nicknamed "W," this marks Meta's first exclusively owned undersea infrastructure. This massive project will connect multiple continents in a W-shaped pattern, linking the U.S. East Coast to India via South Africa, then to Australia and finally returning to the U.S. West Coast. The project, set to begin operations around 2029, represents Meta's strategic move to enhance global connectivity and reduce dependence on third-party networks.
Scientists have made a breakthrough discovery in feline genetics, identifying the specific mutation responsible for orange fur in cats. The research reveals a 5 kb deletion in the Arhgap36 gene on the X chromosome that affects how pigments are distributed in cat hair follicles. This finding explains why orange cats have RNA levels 13 times higher than cats of other colors, and why approximately 80% of orange cats are male.
Our deep dive explores the fascinating scenario of what would happen if humans suddenly vanished from Earth. Drawing from real-world examples like Bulgaria's Tyurkmen region, where abandoned settlements showcase nature's remarkable ability to reclaim spaces, we examine how quickly ecosystems would recover and adapt. From the immediate clearing of pollution to the gradual transformation of urban landscapes and the rebounding of wildlife populations, this journey through a human-free Earth reveals both challenges and opportunities for planetary recovery.
