Why is Biodiversity Important

The intricate network of ecosystems, habitats and species comprising biodiversity provides the support systems that sustain human existence.

Biodiversity gives us many of the essentials of life - oxygen, water, food, clothing, health and relaxation. The value of biodiversity ranges from the spiritual benefits to be gained from contact with nature, to the economic value of crops and livestock. The potential of wild species to provide us with new sources of food or medicines is vast.

However, the world is losing biodiversity at an ever-increasing rate as a result of human activity. In the UK we have lost over 100 species this century, with many more species and habitats in danger of disappearing. On a world scale the rate of loss is now recognised to be a cause for serious concern, requiring concerted international action to prevent continued loss of species and habitats. If we do’t take action, we shall suffer from a loss of the benefits listed above, but we will also pass on to future generations a planet that is much poorer than the one we were privileged to inherit.

Climate Change

Experts now agree that climate change is one of the biggest threats to both people and wildlife. By conserving and enhancing biodiversity we can reduce the impacts of climate change.

Habitats such as saltmarsh, mudflat and sand dune can provide a natural sea defence against the effects of sea level rise and stormy conditions. Habitats such as moorland and peat bogs when in good condition can act as natural sponges soaking up water and releasing it slowly to avoid floods and can also act as carbon stores, preventing carbon dioxide being released into the atmosphere. The distribution of species, particularly when studied over time, can indicate changes in climate, temperature and the seasons.
