It is important to protect biodiversity because it is the key to a sustainable and productive ecosystem. Biodiversity enables most, if not all, of the niches of an ecosystem to be filled. It also serves to protect the food web within the ecosystem, for the higher the biodiversity the lower the effects of removing or changing a species.
