What is one of the main drivers of biodiversity loss?

Invasive species introduction is a significant driver of biodiversity loss because non-native species can disrupt local ecosystems, outcompete native species for resources, and introduce new diseases. When these species are introduced, they often thrive in their new environments because they lack natural predators and regulatory mechanisms that would normally keep their populations in check. This can lead to the decline or extinction of native species, thereby reducing genetic diversity, altering habitats, and impacting the overall stability of ecosystems.

For example, in many freshwater systems, invasive fish species can decimate populations of native fish, disrupting the food web and leading to cascading effects throughout the ecosystem. Similarly, in terrestrial ecosystems, invasive plant species can outcompete native flora for sunlight and nutrients, leading to a loss of native plant diversity, which, in turn, affects the animals that rely on those plants for food and habitat.

In contrast, climate stabilization, improved conservation practices, and enhanced ecosystem management generally contribute positively to biodiversity and ecosystem health, helping to protect and restore native species and their habitats rather than contributing to their decline.
