Humans to Encroach on Over Half of Wildlife Habitats by 2070, Study Finds

Over the next five decades, human expansion into natural habitats is expected to accelerate, threatening biodiversity and raising the risk of future pandemics. Recent research reveals that by 2070, more than half of the Earth’s land will experience increased overlap between human and wildlife populations, driven primarily by population growth.

Currently, human activity has already impacted up to 75% of the planet’s land, transforming ecosystems and contributing to the ongoing biodiversity crisis. As humans encroach further into previously untouched areas, the interactions with wildlife are set to rise, intensifying pressures on species and ecosystems.

This increased proximity between humans and animals not only endangers wildlife but also heightens the potential for disease transmission. Many emerging infectious diseases, such as COVID-19, are zoonotic, meaning they originate in animals and can be transmitted to humans. The loss of biodiversity is a significant factor in these outbreaks, as disruptions in ecosystems can lead to increased contact between wildlife and human populations.

The research, conducted by scientists at the University of Michigan, highlights that the greatest expansion of human-wildlife overlap will occur in regions with already dense populations, including India, China, Africa, and South America. Conversely, some areas, particularly in Europe, may see a reduction in these interactions.
