Invasive seaweed can have devastating ecological impacts on marine habitats, often outcompeting native species for resources. These invasive species can alter nutrient dynamics, shading out light-dependent organisms and disrupting biodiversity. Furthermore, they can smother coral reefs and other critical habitats, leading to declines in fish populations that depend on these ecosystems. The domination of invasive seaweed can also affect local fisheries and economic activities reliant on healthy marine environments. Effective management strategies are necessary to prevent their spread and mitigate these ecological disruptions.
