Why Is Biodiversity Important?

Why is Biodiversity important? Does it really matter if there aren’t so many species?
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.
It has long been feared that human activity is causing massive extinctions. Despite increased efforts at conservation, it has not been enough and biodiversity losses continue. The costs associated with deteriorating or vanishing ecosystems will be high. However, sustainable development and consumption would help avert ecological problems.
Preserving species and their habitats is important for ecosystems to self-sustain themselves.
Yet, the pressures to destroy habitat for logging, illegal hunting, and other challenges are making conservation a struggle.

Rapid global warming can affect ecosystems chances to adapt naturally.
The Arctic is very sensitive to climate change and already seeing lots of changes. Ocean biodiversity is already being affected as are other parts of the ecosystem.
One type of ecosystem that perhaps is neglected more than any other is perhaps also the richest in biodiversity—the coral reefs.
Coral reefs are useful to the environment and to people in a number of ways. However, all around the world, much of the world’s marine biodiversity face threats from human and activities as well as natural. It is feared that very soon, many reefs could die off..
At the 1992 UN Conference on Environment and Development (the Earth Summit), the Convention on Biological Diversity (CBD) was born. 192 countries, plus the EU, are now Parties to that convention. In April 2002, the Parties to the Convention committed to significantly reduce the loss of biodiversity loss by 2010.
Perhaps predictably, that did not happen. Despite numerous successful conservations measures supporting biodiversity, the 2010 biodiversity target has not been met at the global level. This page provides an overview on how the attempt to prevent biodiversity loss is progressing
