Why is it important to preserve biodiversity?

Preserving biodiversity is crucial for maintaining the balance of ecosystem services. Ecosystem services are the benefits that humans derive from ecosystems, including clean air and water, pollination of crops, soil fertility, climate regulation, and habitat for wildlife. When biodiversity is high, ecosystems are generally more resilient and can better withstand environmental stressors such as climate change, disease, and invasive species.

A diverse range of species contributes to the health of an ecosystem by performing different roles, such as predators controlling prey populations or plants contributing to soil health. When species are lost, particularly keystone species, the entire ecosystem may suffer, leading to a cascade of negative effects on both ecological balance and human well-being. Thus, preserving biodiversity is essential not just for the species themselves, but for the continued provision of vital ecosystem services that support life on Earth.
