The Impact of Invasive Species on Ecosystems and Economies
Invasive species are organisms that have been moved to a new part of the world by humans and cause significant damage to the ecosystem, economy, and even human health. They can outcompete native species, introduce diseases, and disrupt natural habitats. For example, the grey squirrel wiped out the red squirrels through disease transmission, and the floating pennywort and zebra/quagga mussels clog waterways, impacting water systems and drainage infrastructure. Invasive species cost the UK economy approximately £1.6 billion annually. While there are methods like biocontrol and genome modification being explored to manage invasive species, the potential risks and unintended consequences need thorough consideration.
