Biodiversity refers to the variety of life on Earth and can be observed at genetic, species, and ecosystem levels. The main threats to biodiversity are habitat loss, climate change, overexploitation, invasive species, and pollution. Some actions that can help address these threats include educating others, reducing pollution and energy use, sustainable practices, protecting habitats, and preventing invasive species spread. A case study from Kokkare Bellure, India shows how local people have protected endangered birds that bring benefits, demonstrating coexistence of humans and wildlife. All species have a right to survive on Earth.
