We Ignore Thousands of Threatened Plant Species at Our Peril
Plants play an essential role in our lives, providing food, clothing, shelter, medicine, and oxygen, and supporting diverse ecosystems. Their roots promote soil health, control erosion, and improve water quality. Moreover, plants act as natural carbon sinks, absorbing carbon dioxide from the atmosphere through photosynthesis. Despite their crucial contributions, however, plants often receive less attention compared to animals. But one thing is certain: The fate of plant species is equally critical for human survival.
A study conducted by experts at the Royal Botanic Gardens in London found that over 20 percent of the world’s known plant species are at risk of extinction. Without immediate action, this figure is unlikely to improve, given the mounting challenges faced by all species on Earth.
Hawaiian tree cotton, known as kokio, is a prime example of the dire situation faced by plant species. Overgrazing by non-native animals, competition from weeds, wildfires, and habitat loss have pushed kokio to the brink of extinction. Despite efforts by organizations like the Plant Extinction Prevention Program (PEPP), which aims to protect endangered Hawaiian plants, funding reductions have hindered their conservation efforts.
Hawai’i is recognized as the “extinction capital of the world,” with 44 percent of endangered and threatened plant species in the United States originating in the state, though it comprises less than one percent of the nation’s land mass. The International Union for the Conservation of Nature’s Red List includes more than 230 endangered Hawaiian plant species.
The Kew study identified several threats to plant species, including agricultural destruction, biological resource use, residential and commercial development, invasive species, and climate change. Climate change poses a significant challenge, with extreme temperatures and precipitation events disrupting plant ecosystems and threatening pollinators.
To protect endangered plant species from extinction, we must fight for the defense and strengthening of the Endangered Species Act. Supporting conservation programs, donating, volunteering, and maintaining native plant habitats are also essential steps. Additionally, addressing climate change by reducing emissions and urging policymakers to prioritize environmental policies is vital.
The survival of threatened plant species depends on urgent action. By recognizing their significance and supporting conservation efforts, we can ensure the preservation of vital ecosystems. Protecting these species not only benefits biodiversity but also safeguards the cultural and historical heritage embedded in our environment. It is our responsibility to act now before these invaluable plants disappear forever.
