What is a major threat to biodiversity today?

• A. Climate stabilization
• B. Invasive species
• C. Reforestation
• D. Increased pollinator populations

Answer: (B)

Invasive species are considered a major threat to biodiversity today because they can disrupt local ecosystems, outcompete native species for resources, and introduce diseases that native species are not equipped to handle. When non-native plants and animals establish themselves in a new environment, they often lack natural predators, which allows them to proliferate unchecked. This can lead to significant ecological imbalances, as native species may decline or be driven to extinction due to the competition for food, habitat, and other resources. Such disruptions can fundamentally alter the structure and function of ecosystems, further threatening overall biodiversity. Understanding and managing invasive species is crucial for conservation efforts aimed at preserving the complexity and diversity of ecosystems.
