Biodiversity:
Biological diversity, or biodiversity, refers to the variety of life on Earth. As defined by the United Nations Convention on Biological Diversity, it includes diversity of ecosystems, species and genes, and the ecological processes that support them. Natural diversity in ecosystems provides essential economic benefits and services to human society—such as food, clothing, shelter, fuel and medicines—as well as ecological, recreational, cultural and aesthetic values, and thus plays an important role in sustainable development. Biodiversity is under threat in many areas of the world. Concern about global biodiversity loss has emerged as a prominent and widespread public issue.
We recognize the importance of biodiversity conservation and support it through our values, performance, and communication and engagement.
Types of biodiversity
Genetic diversity - the genetic variability within a species.
Species diversity - the variety of species within a community.
Ecosystem diversity - the organization of species in an area into distinctive plant and animal communities
Why Is Biodiversity Important? Who Cares?
Why is Biodiversity important? Does it really matter if there aren’t so Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play.
For example, a larger number of plant species means a greater variety of crops; greater species diversity ensures natural sustainability for all life forms; and healthy ecosystems can better withstand and recover from a variety of disasters.
And so, while we dominate this planet, we still need to preserve the diversity in wildlife.
Loss of Biodiversity and Extinctions
It has long been feared that human activity is causing massive extinctions. Despite increased efforts at conservation, it has
