Humans To Push Further Into Wildlife Habitats Across More Than 50% of Land by 2070, Study Says

Over the next 50 years, people will push further into wildlife habitats across more than half the land on Earth, scientists have found, threatening biodiversity and increasing the chance of future pandemics. From a report: Humans have already transformed or occupied between 70% and 75% of the world's land. Research published in Science Advances on Wednesday found the overlap between human and wildlife populations is expected to increase across 57% of the Earth's land by 2070, driven by human population growth.

As humans and animals share increasingly crowded landscapes, the bigger overlap could result in higher potential for disease transmission, biodiversity loss, animals being killed by people and wildlife eating livestock and crops, the researchers said. Biodiversity loss is the leading driver of infectious disease outbreaks. About 75% of emerging diseases in humans are zoonotic, meaning they can be passed from animals to humans, and many diseases concerning global health authorities -- including Covid-19, mpox, avian flu and swine flu -- likely originated in wildlife.
