Why is biodiversity important?
Biodiversity matters. At its simplest, biodiversity is about living nature or life on Earth - different genes, species and ecologies and, as a consequence, the varying landscapes, regions and habitats in which they exist.
Biodiversity provides food, water and shelter; influences climate; controls disease; and regulates nutrient and water cycles. Biodiversity is integral to spiritual, cultural, psychological and artistic well-being. Biodiversity also has its own intrinsic worth distinct from human life. Humans are embedded in the natural world, and so a part of biodiversity.
Acting against biodiversity loss
Today, however, the Earth is losing biodiversity at rates not seen in the modern era. Human responses to stop biodiversity decline have been woefully inadequate – with targets missed at both the international and national levels. This represents a significant policy failure.
But there is hope. This year represents an important opportunity for policymakers within the UK and internationally to reflect on and respond to the significant threats to biodiversity. Key policy moments include:
- the United Nations Convention on Biological Diversity 15th Conference of the Parties in Kunming, China
- the United Nations Framework Convention on Climate Change 26th Conference of the Parties in Glasgow, UK
- the publication in February 2021 of the independent The Economics of Biodiversity: The Dasgupta Review commissioned by the UK Treasury and led by Partha Dasgupta FRS
- the G7 leaders’ summit in Cornwall, UK and the publication of a statement on biodiversity loss by the Science Academies of the G7
Exploring the science behind biodiversity loss
To strengthen the scientific evidence base on biodiversity and make this available to policymakers, the Royal Society has commissioned a series of essays from global experts in fields as diverse as conservation, ecology, environmental change, economics and population. They are intended to stimulate discussion on the problems and potential solutions to halt and reverse the decline in biodiversity. The essays are available below.
