Why scientist concerned that currently unknown medicinal plants may never be discovered?

Scientists are concerned that currently unknown medicinal plants may never be discovered due to rapid habitat loss, deforestation, and climate change, which threaten biodiversity. As ecosystems are destroyed, unique plant species that could possess untapped medicinal properties may become extinct before they are identified and studied. Additionally, traditional knowledge about these plants, often held by indigenous communities, is at risk of being lost, further diminishing the potential for discovering new medicines. This loss could hinder advancements in pharmaceuticals and treatments for various health conditions.
