Climate change is shrinking global habitats and threatening tens of thousands of plant species with extinction by the end of the century [3].
This loss of biodiversity threatens the stability of global ecosystems. Plants form the foundation of most food chains, and their disappearance could trigger a cascade of failures affecting insects, animals, and human food security.
A study published in the journal Science highlights the accelerating threat to plant biodiversity [4]. Researchers found that rising temperatures and shifting climate zones are reducing the areas where various species can survive. These environmental shifts are pushing plants out of their natural ranges faster than they can adapt or migrate.
The scale of the projected loss is significant. Between seven percent and 16 percent of global plant species are expected to lose more than 90 percent of their range by 2100 [1]. This suggests that one in six plant species on Earth are at risk of dying out within 75 years [2].
These risks are evident in specific regions across the globe. Researchers pointed to the West MacDonnell Ranges in Australia as an example of where shrinking habitats are impacting local flora [5]. As climate zones shift, the specialized conditions required for these plants to thrive are disappearing.
Scientists said that the danger extends to tens of thousands of species worldwide [3]. The reduction in suitable habitats is not limited to a single continent but is a global phenomenon driven by the systemic rise in temperatures [6].
“One in six plant species on Earth are at risk of dying out within 75 years.”
The potential collapse of a significant percentage of plant life represents a systemic risk to planetary health. Because plants regulate atmospheric carbon and provide the primary energy source for terrestrial life, the loss of 16% of species would likely destabilize carbon sequestration efforts and disrupt agricultural pollination, creating a feedback loop that could further accelerate warming.
