Biodiversity is the variety of all the different species of organisms on
earth, or within an ecosystem.
A great biodiversity ensures the stability of ecosystems by reducing
the dependence of one species on another for food, shelter and the
maintenance of the physical environment.
The future of the human species on Earth relies on us maintaining a
good level of biodiversity. Many human activities are reducing
biodiversity and only recently have measures been taken to try to
stop this reduction.
