Biodiversity is the entire array of living species that make up habitats and ecosystems. When that diversity is threatened - through deforestation, urban development, land-use change, or pollution - the integrity of the ecosystem is compromised. Biodiversity: Journal of Life on Earth is a peer reviewed science journal published in partnership with Taylor & Francis journals in the UK. The articles below were written over the past 10 years when I was Managing Editor and, more recently, Senior Editor for Biodiversity. I hope this information adds to the understanding of the need for wild diversity and encourages respect for all life on Earth.
