For this is the year by which the world’s governments solemnly swore that they would be beating back the biodiversity crisis, which threatens to bring about the sixth mass extinction of species in the lifetime of our planet, and the fi rst since the disappearance of the dinosaurs 65 million years ago. To be precise, world leaders pledged, early last decade, ‘to achieve, by 2010, a signifi cant reduction of the current rate of biodiversity loss MANY SPECIES • ONE PLANET • ONE FUTURE at the global, regional and national level, as a contribution to WORLD ENVIRONMENT DAY • 5 JUNE 2010 poverty alleviation and to the benefi t of all life on Earth.’ As the pledge indicates, the biodiversity crisis is not just about vanishing species, important though that is. It is also destroying the vital services that nature provides for humanity. We depend on soils and seas for food, for example, on forests for freshwater, on trees to reduce What YOU can do pollution, on wild species for many of our medicines. And yet half of the world’s wetlands have been lost over One person alone cannot save the planet’s biodiversity, the last century; 40 per cent of its forests in just the last but each individual’s effort to encourage nature’s wealth three decades.

In October repre- sentatives of almost all the world’s nations will be in Japan for a meeting of the Convention on Biological Diversity. One of the subjects they’ll discuss is the 2010 biodiversity target, an agree- ment made eight years ago to try to stop the loss of biodiversity by 2010 – something we know we haven’t achieved. But how many people, even among those meeting in Japan, really understand biodiversity? What is it? Can we measure it? Does it really matter if we lose it, or some of it? What will happen if we do? Where is it? Some kinds of habitat have far more species than others. Those with the most are tropical rainforests; other rich habitats in clude coral reefs, and scrublands in a Mediterranean-type climate, which are particularly rich in plant species. In contrast, very cold and dry places – the Arctic and Antarctic, and deserts such as the Sahara – have very few. How much of it is there? When it comes to living organisms It’s much harder to say how many we can at least have a go at count ing different kinds of ecosystem or habi- them. We usually do this in terms of tat there are. People can’t agree on What is biodiversity? species – a kind of universal currency a way of classifying them, and in any Biodiversity is really just one way of biodiversity.
