As far as we know, the world we inhabit is one of a kind. 

Life began as single celled organisms long ago, and in the hundreds of millions of years that followed, complex life evolved. Continuous evolution and speciation through the process of natural selection, has led to a world rich in diversity and wonder. Each species is continuously adapting to the environments they face, yet accelerated climate change causes many specialised species to struggle with such quick shifts in their world. 

Biodiversity is so special and without it the world would be a dull place.
