Tools for advancing the objectives of the Convention are well developed, and include the pro- grammes of work addressing each major biome and practical guidelines for action. Th e challenge now is to put these tools to wide use across all economic sec- tors—from fi sheries to forestry, agriculture to indus- try, planning to trade. Now is the time for cooperation and collaboration. Th e Convention has a toolkit for tackling a variety of globally-relevant issues, and the 2010 framework to guide strategies and achieve clear outcomes. It is up to the Parties to the Convention to enact national mech- anisms for sustainable development that are mindful of the three objectives of the Convention. Th e citizens of the world are increasingly aware of environmen- tal change, and concerned by all that stands to be lost. Together, we must take immediate and eff ective action. Why should all the good ideas and eff orts of over a decade of meetings under the Convention remain only on paper? Why should we restrict ourselves to dialogue only within the environmental community, when all economic sectors have a stake in halting biodiversity loss? It is time to translate our hopes and energies into action, for the sake of all life on Earth.

We examine the dimensions and nature of the Earth’s terrestrial biodiversity and review the scientific facts concerning the rate of loss of biodiversity and the drivers of this loss. The estimate for the total number of species of eukaryotic organisms possible lies in the 5–15 million range, with a best guess of 7 million. Species diversity is unevenly distributed; the highest concentrations are in tropical ecosystems. Endemisms are concentrated in a few hotspots, which are in turn seriously threatened by habitat destruction—the most prominent driver of biodiversity loss. For the past 300 years, recorded extinctions for a few groups of organisms reveal rates of extinction at least several hundred times the rate expected on the basis of the geological record. The loss of biodiversity is the only truly irreversible global environmental change the Earth faces today.

Around 1,500 living species of starfish occur on the seabed in all the world's oceans, from the tropics to subzero polar waters. They are found from the intertidal zone down to abyssal depths, 6,000m below the surface. Starfish typically have a central disc and five arms, though some species have a larger number of arms. The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates.

    31 MARCH 2021 Reversing biodiversity loss – the case for urgent action This statement has been created by the Science Academies of the Group of Seven (G7) nations. It represents the Academies’ view on the magnitude of biodiversity decline and the urgent action required to halt and reverse this trend.
